WaveRunner 8000 Oscilloscopes Instruction Manual

Operating Environment
Temperature: 5 to 40° C.
Humidity: Maximum relative humidity 90 % for temperatures up to 31° C, decreasing linearly to 50%
relative humidity at 40° C.
Altitude: Up to 3,000 m at or below 30° C.

Cooling
The instrument relies on forced air cooling with internal fans and vents. Take care to avoid restricting the
airflow to any part. In a benchtop configuration, leave a minimum of 15 cm (6 inches) around the sides
between the instrument and the nearest object. The feet provide adequate bottom clearance. Follow
rackmount instructions for proper rack spacing.
Caution: Do not block the cooling vents.
The instrument also has internal fan control circuitry that regulates the fan speed based on the ambient
temperature. This is performed automatically after start-up.

Cleaning
Clean only the exterior of the instrument using a soft cloth moistened with water or an isopropyl alcohol
solution. Do not use harsh chemicals or abrasive elements. Under no circumstances submerge the
instrument or allow moisture to penetrate it. Dry the instrument thoroughly before connecting a live
voltage source.
Caution: Unplug the power cord from the AC inlet before cleaning to avoid electric shock. Do not
attempt to clean internal parts. Refer all maintenance to qualified service personnel.

Safety

Power
AC Power
The instrument operates from a single-phase, 100-240 Vrms (± 10%) AC power source at 50/60 Hz (± 5%)
or a 100-120 Vrms (± 10%) AC power source at 400 Hz (± 5%). Manual voltage selection is not required
because the instrument automatically adapts to the line voltage.

Power Consumption
Maximum power consumption with all accessories installed (e.g., active probes, USB peripherals, digital
leadset) is 375 W (375 VA) for non-"M" models and 500 W (500 VA) for "M" models. Power consumption in
Standby mode is 15 W.

Ground
The AC inlet ground is connected directly to the frame of the instrument. For adequate protection again
electric shock, connect to a mating outlet with a safety ground contact.
Caution: Use only the power cord provided with your instrument. Interrupting the protective
conductor (inside or outside the case), or disconnecting the safety ground terminal, creates a
hazardous situation. Intentional interruption is prohibited.

Front Panel
Front panel controls duplicate functionality available through the
touch screen and are described here only briefly.
Knobs on the front panel function one way if turned and another if
pushed like a button. The first label describes the knob’s “turn”
action, the second label its “push” action. Actions performed from
the front panel always apply to the active trace.
Many buttons light to show the active traces and functions.

Trigger Controls
The front panel Level knob changes the trigger threshold level
(V). The number is shown on the Trigger descriptor box. Pushing
the knob sets the trigger level to the 50% point of the input signal.
The READY indicator is lit when the trigger is armed. TRIG'D is lit
momentarily when a trigger occurs.
Setup opens the Trigger Setup dialog. Press it again to close the
dialog.
Auto sets Auto mode, which triggers the oscilloscope after a set
time, even if the trigger conditions are not met.
Normal sets Normal mode, which triggers the oscilloscope each
time a signal is present that meets the trigger conditions.

meets the trigger conditions.

Single sets Single trigger mode. The first press readies the
oscilloscope to trigger. The second press arms and triggers the
oscilloscope once (single-shot acquisition) when the input signal

Stop prevents the scope from triggering on a signal. If you boot up the instrument with the trigger in Stop
mode, a "No trace available" message is shown. Press the Auto button to display a trace.

Horizontal Controls
Turn the Delay knob to change the Trigger Delay value (S). Push the knob to reset Delay to zero.
If the trace source is an input channel, turn the Horizontal Adjust knob to set the Time/division (S) of the
oscilloscope acquisition system. The value is shown on the Timebase descriptor box. When using this
control, the oscilloscope allocates memory as needed to maintain the highest sample rate possible for the
timebase setting. If the trace source is a zoom, memory or math function, turn the knob to change the
horizontal scale of the trace, effectively "zooming" in or out. The value is shown on the corresponding
descriptor box. Push the knob to change the setting in fine increments; push it again to return to 1, 2, 5, 10step increments.

Oscilloscope Overview

Vertical Controls
Offset knob adjusts the zero level of the trace (this makes it appear to move up or down relative to the
center axis of the grid). The value appears on the trace descriptor box. Push it to reset Offset to zero.
Gain knob sets Vertical Gain (V/div). The value appears on the trace descriptor box. Push it once to adjust
V/div in fine increments; push it again to adjust in 1, 2, 5, 10-step increments.
The Channel buttons (1-4) turn on a channel that is off, or activate a channel that is already on. When the
channel is active, pushing its channel button turns it off. A lit button shows the active channel.
Dig button enables digital input on -MS models.

Math, Zoom, and Mem Buttons
The front panel Zoom button creates a quick zoom of each open channel trace. The resulting zoom traces
are 1/10 of the channel timebase and centered on the display. Touch the zoom trace descriptor box to
display the zoom controls and adjust this. Touch the Zoom button again to turn off the zooms.
The Math and Mem(ory) buttons open the corresponding setup dialogs.

Cursor Controls
Cursors identify specific voltage and time values on the waveform. The white cursor markers help make
these points more visible, as well as provide a simple way to reposition them. A readout of the values
appears on the trace descriptor box.
There are five preset cursor types, each with a unique appearance on the display. These are described in
more detail in the Cursors section.
Press the front panel Type button to apply or remove cursors. Continue pressing to cycle through all cursor
types until the desired type is found ("no cursors" will appear in the cycle).
Turn the Cursor knob to reposition the selected cursor line. Push it to select a different cursor line to
adjust.

Adjust & Intensity
The front panel Adjust knob changes the value in active (highlighted) data entry fields that do not have
dedicated knobs. Pushing Adjust toggles between coarse (large increment) or fine (small increment)
adjustments when the knob is turned.
The Intensity button sets the Adjust knob to control the trace intensity. When more data is available than
can actually be displayed, the Intensity button helps to visualize significant events by applying an algorithm
that dims less frequently occurring samples. This feature can also be accessed from the Display Setup
dialog.

Oscilloscope Overview

Signal Interfaces
The instrument offers a variety of interfaces for using probes or other devices to input analog or digital
signals. See the product page at teledynelecroy.com for a list of compatible devices.

Analog Inputs
A series of connectors arranged on the front of the instrument are used to input analog signals on
channels 1-4. EXT can be used to input an external trigger pulse or sample clock signal.
WaveRunner 8000 channel connectors use the ProBus interface. The ProBus interface contains a 6-pin
power and communication connection and a BNC signal connection to the probe. It includes sense rings
for detecting passive probes and accepts a BNC cable connected directly to it. ProBus offers 50 Ω and 1
MΩ input impedance and control for a wide range of probes.
The channel interfaces power probes and completely integrate the probe with the channel. Upon
connection, the probe type is recognized and some setup information, such as input coupling and
attenuation, is performed automatically. This information is displayed on the Probe Dialog, behind the
Channel (Cx) dialog. System (probe plus instrument) gain settings are automatically calculated and
displayed based on the probe attenuation.

Probes
The oscilloscope is compatible with the included passive probes and most Teledyne LeCroy ProBus active
probes that are rated for the instrument’s bandwidth. Probe specifications and documentation are
available at teledynelecroy.com/probes.

Passive Probes
The passive probes supplied are matched to the input impedance of the instrument but may need further
compensation. If using other passive probes, be sure to perform a low frequency calibration using the Cal
signal available from the front panel before using them to measure signal. Follow the directions in the
probe instruction manual to compensate the frequency response of the probes.

Active Probes
Most active probes match probe to oscilloscope response automatically using probe response data stored
in an on-board EEPROM. This ensures the best possible combined probe plus oscilloscope channel
frequency response without the need to perform any de-embedding procedure.
Be aware that many active probes require a minimum oscilloscope firmware version to be fully
operational. See the probe documentation.

WaveRunner 8000 Oscilloscopes Instruction Manual

Digital Leadset
The digital leadset provided with -MS model
oscilloscopes enables input of up-to-16 lines of
digital data. Lines can be organized into four
logical groups and renamed appropriately.
The digital leadset features two digital banks with
separate Threshold controls, making it possible to
simultaneously view data from different logic
families.

Connecting/Disconnecting the Leadset
The digital leadset connects to the Mixed Signal interface on the front of the instrument.
To connect the leadset to the instrument, push the connector into the Mixed Signal interface below the
front panel until you hear a click.
To remove the leadset, press and hold the buttons on each side of the connector, then pull out to release.

Grounding Leads
Each flying lead has a signal and a ground connection. A variety of ground extenders and flying ground
leads are available for different probing needs.
To achieve optimal signal integrity, connect the ground at the tip of the flying lead for each input used in
your measurements. Use either the provided ground extenders or ground flying leads to make the ground
connection.

Oscilloscope Set Up

Oscilloscope Set Up
Powering On/Off
Press the Power button to turn on the instrument. The X-Stream application loads automatically
when you use the Power button.
Caution: Do not change the instrument’s Windows® Power Options setting from the default Never
to System Standby or System Hibernate. Doing so can cause the system to fail.
Caution: Do not power on or calibrate with a signal attached.
The safest way to power down the oscilloscope is to use the File > Shutdown menu option, which will
always execute a proper shut down process and preserve settings. Quickly pressing the power button
should also execute a proper shut down, but holding the Power button will execute a “hard” shut down (as
on a computer), which we do not recommend doing because it does not allow the Windows operating
system to close properly, and setup data may be lost. Never power off by pulling the power cord from the
socket or powering off a connected power strip or battery without first shutting down properly.
The Power button does not disconnect the instrument from the AC power supply. The only way to fully
power down the instrument is to unplug the AC power cord.
We recommend unplugging the instrument if it will remain unused for a long period of time.

Software Activation
The operating software (firmware and standard applications) is active upon delivery. At power-up, the
instrument loads the software automatically.

Firmware
Free firmware updates are available periodically from the Teledyne LeCroy website at:
teledynelecroy.com/support/softwaredownload
Registered users can receive an email notification when a new update is released. Follow the instructions
on the website to download and install the software.

Purchased Options
If you decide to purchase an option, you will receive a license key via email that activates the optional
features. See Options for instructions on activating optional software packages.

Using MAUI

Using MAUI
MAUI, the Most Advanced User Interface, is Teledyne LeCroy's unique oscilloscope user interface. MAUI is
designed for touch—all important controls for vertical, horizontal, and trigger are only one touch away.

Touch Screen
The touch screen is the principal viewing and control center. The entire display area is active: use your
finger or a stylus to touch, drag, swipe, or draw a selection box.
Many controls that display information also work as “buttons” to access other functions. If you have a
mouse installed, you can click anywhere you can touch to activate a control; in fact, you can alternate
between clicking and touching, whichever is convenient for you.
The touch screen is divided into the following major control groups:
l

Menu bar

Grid area

Descriptor boxes

Dialogs

Message Bar

Menu Bar
The top of the window contains a complete menu of functions. Making a selection here changes the
dialogs displayed at the bottom of the screen.
While many common operations can also be performed from the front panel or launched via the
descriptor boxes, the menu bar is the best way to access dialogs for Save/Recall (File) functions, Display
functions, Status, LabNotebook, Pass/Fail setup, and Utilities/Preferences setup.
You will see a Q-Scape
control added to the menu bar when the Q-Scape option is
installed. This allows you to choose different tabbed display configurations. See Display.
If an action can be “undone”, a small Undo
button appears at the far right of the menu bar. Click this
to restore the oscilloscope to the state prior to the action.

WaveRunner 8000 Oscilloscopes Instruction Manual

Grid Area
The grid area displays the waveform traces. Every grid is 8 Vertical divisions representing 256 Vertical
levels and 10 Horizontal divisions each representing acquisition time. The value represented by Vertical
and Horizontal divisions depends on the Vertical and Horizontal scale of the traces that appear on the grid.

Multi-Grid Display
The grid area can be divided into multiple grids showing different types and numbers of traces (in Auto
Grid mode, it will divide automatically as needed). Regardless of the number and orientation of grids, every
grid always represents the same number of Vertical levels. Therefore, absolute Vertical measurement
precision is maintained.

Different types of traces opening in a multi-grid display.

Q-Scape Tabs
On instruments with the Q-Scape option installed, Tabs 1-4 appear along the top of the grid area. Each tab
is a distinct multi-grid display. See Display for more information about using Q-Scape.

Using MAUI

Grid Indicators
These indicators appear around or on the grid to mark important points on the display. They are matched
to the color of the trace to which they apply. When multiple traces appear on the same grid, indicators
refer to the foreground trace—the one that appears on top of the others.
Axis labels mark the times/units represented by a grid division. They update dynamically as you pan the trace
or change the Vertical/Horizontal scale. Originally shown in absolute values, the labels change to show delta
from 0 (center) when the number of significant digits grows too large. The number of labels that appear on
each grid depends on the total number of grids open. To remove them, go to Display > Display Setup and
deselect Axis Labels.
Trigger Time, a small triangle along the bottom (horizontal) edge of the grid, shows the time of the trigger.
Unless Horizontal Delay is set, this indicator is at the zero (center) point of the grid. Delay time is shown at the
top right of the Timebase descriptor box.
Pre/Post-trigger Delay, a small arrow to the bottom left or right of the grid, indicates that a pre- or post-trigger
Delay has shifted the Trigger Position indicator to a point in time not displayed on the grid. All Delay values
are shown on the Timebase Descriptor Box.
Trigger Level at the right edge of the grid tracks the trigger voltage level. If you change the trigger level when
in Stop trigger mode, or in Normal or Single mode without a valid trigger, a hollow triangle of the same color
appears at the new trigger level. The trigger level indicator is not shown if the triggering channel is not displayed.
Zero Volts Level is located at the left edge of the grid. One appears for each open trace on the grid, sharing
the number and color of the trace.
Cursor markers appear over the grid to indicate specific voltage and time values on the waveform. Dragand-drop cursor markers to quickly reposition them.

Grid Intensity
You can adjust the brightness of the grid lines by going to Display > Display Setup and entering a new Grid
Intensity percentage. The higher the number, the brighter and bolder the grid lines.

WaveRunner 8000 Oscilloscopes Instruction Manual

Descriptor Boxes
Trace descriptor boxes appear just beneath the grid whenever a trace is turned on. They function to:
l

Inform—descriptors summarize the current trace settings and its activity status.
Navigate—touch the descriptor box once to activate the trace, a second time to open the trace
setup dialog.

Arrange—drag-and-drop descriptor boxes to move traces among grids.

Configure—drag-and-drop descriptor boxes to change source or copy setups.

Besides trace descriptor boxes, there are also Timebase and Trigger descriptor boxes summarizing the
acquisition settings shared by all channels, which also open the corresponding setup dialogs.

Channel Descriptor Box
Channel trace descriptor boxes correspond to analog signal inputs. They show
(clockwise from top left): Channel Number, Pre-processing list, Coupling, Vertical Scale
(gain) setting, Vertical Offset setting, Sweeps Count (when averaging), Vertical Cursor
positions, and Number of Segments (when in Sequence mode).
Codes are used to indicate pre-processing that has been applied to the input. The short
form is used when several processes are in effect.

Other Trace Descriptor Boxes
Similar descriptor boxes appear for math (Fx), zoom (Zx), and memory (Mx) traces. These descriptor
boxes show any Horizontal scaling that differs from the signal timebase. Units will be automatically
adjusted for the type of trace.

Trace Context Menu
Touch and hold ("right-click") on the trace descriptor box until a white circle appears to open the trace
context menu, a pop-up menu of actions to apply to the trace such as turn off, move to next grid or label.

Timebase and Trigger Descriptor Boxes
The Timebase descriptor box shows: (clockwise from top right) Horizontal Delay, Time/div, Sample Rate,
Number of Samples, and Sampling Mode (blank when in real-time mode).
Trigger descriptor box shows: (clockwise from top right) Trigger Source and Coupling, Trigger Level (V),
Slope/Polarity, Trigger Type, Trigger Mode.

Horizontal (time) cursor readout, including the time between cursors and the frequency, is shown beneath
the TimeBase and Trigger descriptor boxes. See the Cursors section for more information.

WaveRunner 8000 Oscilloscopes Instruction Manual

Dialogs
Dialogs appear at the bottom of the display for entering setup data. The top dialog will be the main entry
point for the selected functionality. For convenience, related dialogs appear as a series of tabs behind the
main dialog. Touch the tab to open the dialog.

Right-Hand Subdialogs
At times, your selections will require more settings than can fit on one dialog, or the task commonly invites
further action, such as zooming a new trace. In that case, subdialogs will appear to the right of the dialog.
These subdialog settings always apply to the object that is being configured on the left-hand dialog.

Action Toolbar
Several setup dialogs contain a toolbar at the bottom of the dialog. These buttons enable you to perform
commonplace tasks—such as turning on a measurement—without having to leave the underlying dialog.
Toolbar actions always apply to the active trace.

Measure opens the Measure pop-up to set measurement parameters on the active trace.
Zoom creates a zoom trace of the active trace.
Math opens the Math pop-up to apply math functions to the active trace and create a new math trace.
Decode opens the main Serial Decode dialog where you configure and apply serial data decoders and
triggers. This button is only active if you have serial data software options installed.
Store loads the active trace into the corresponding memory location (C1, F1 and Z1 to M1; C2, F2 and Z2
to M2, etc.).
Find Scale performs a vertical scaling that fits the waveform into the grid.
Next Grid moves the active trace to the next grid. If you have only one grid displayed, a new grid will be
created automatically, and the trace moved.
Label opens the Label pop-up to annotate the active trace.

Using MAUI
Histogram, Trend, and Track buttons appear at the bottom of the Parameter (Px) dialogs. They allow you
to create a Math function to plot the parameter while remaining on the measurement dialogs.

Message Bar
At the bottom of the oscilloscope display is a narrow message bar. The current date and time are
displayed at the far right. Status, error, or other messages are also shown at the far left, where "Teledyne
LeCroy" normally appears.

You will see the word "Processing..." highlighted with red at the right of the message bar when the
oscilloscope is processing your last acquisition or calculating.

This will be especially evident when you change an acquisition setting that affects the ADC configuration
in Normal or Auto trigger mode, such as changing the Vertical Scale, Offset, or Bandwidth. Traces may
briefly disappear from the display while the oscilloscope is processing.

WaveRunner 8000 Oscilloscopes Instruction Manual

OneTouch Help
Touch, drag, swipe, pinch, and flick can be used to create and change setups with one touch. Just as you
change the display by using the setup dialogs, you can change the setups by moving different display
objects. Use the setup dialogs to refine OneTouch actions to precise values.
As you drag & drop objects, valid targets are outlined with a white box. When you're moving over invalid
targets, you'll see the "Null" symbol ( Ø ) under your finger tip or cursor.
Note: Many actions shown here—such as Activate, Position Cursors, Change Trigger, Move Trace,
Scroll, Pan left/right, and Drag to Create Zoom—can be done on all MAUI instruments, even those
without the OneTouch features. Some examples below may show features not available on your
oscilloscope.

Turn On
To turn on a new channel, math, memory, or zoom trace, drag any descriptor box of the same type to the
Add New ("+") box. The next trace in the series will be added to the display at the default settings. It is now
the active trace.

If there is no descriptor box of the desired type on the screen to drag, touch the Add New box and choose
the trace type from the pop-up menu.
To turn on the Measure table when it is closed, touch the Add New box and choose Measurement.

Activate
Touch a trace or its descriptor box to activate it and bring it to the foreground. When the descriptor box
appears highlighted in blue, front panel controls and touch screen gestures apply to that trace.

Using MAUI

Copy Setups
To copy the setup of one trace to another of the same type (e.g., channel to channel, math to math),
drag-and-drop the source descriptor box onto the target descriptor box.

To copy the setup of a measurement (Px), drag-and-drop the source column onto the target column of
the Measure table. You can do the same for a qualifier (Qx) on the Pass/Fail readout table.

Change Source
To change the source of a trace, drag-and-drop the descriptor box of the desired source onto the target
descriptor box. You can also drop it on the Source field of the target setup dialog.

To change the source of a measurement, drag-and-drop the descriptor box of the desired source onto
the parameter (Px) column of the Measure table. You can do the same to a qualifier (Qx) on the Pass/Fail
readout table.

WaveRunner 8000 Oscilloscopes Instruction Manual

Position Cursors
To change cursor measurement time/level, drag cursor markers to new positions on the grid. The cursor
readout will update immediately.

To place horizontal cursors on zooms or other calculated traces where the source Horizontal Scale has
forced cursors off the grid, drag the cursor readout from below the Timebase descriptor to the grid where
you wish to place the cursors. The cursors are set at either the 5 (center) or 2.5 and 7.5 divisions of the
grid. Cursors on the source traces adjust position accordingly.

Change Trigger
To change the trigger level, drag the Trigger Level indicator to a new position on the Y axis. The Trigger
descriptor box will show the new voltage Level.

To change the trigger source channel, drag-and-drop the desired channel (Cx) descriptor box onto the
Trigger descriptor box. The trigger will revert to the coupling and slope/polarity last set on that channel.

Using MAUI

Store to Memory
To store a trace to internal memory, drag-and-drop its trace descriptor box onto the target memory (Mx)
descriptor box.

Move Trace
To move a trace to a different grid, drag-and-drop the trace descriptor box onto the target grid. If you are
in a multi-tabbed Q-Scape display mode, you can move traces between tabs this way.

Scroll
To scroll long lists of values or readout tables, swipe the selection dialog or table in an up or down
direction.

WaveRunner 8000 Oscilloscopes Instruction Manual

Pan Trace
To pan a trace, activate it to bring it to the forefront, then drag the waveform trace right/left or up/down. If
it is the source of any other trace, that trace will move, as well. For channel traces, the Timebase
descriptor box will show the new Horizontal Delay value. For other traces, the zoom factor controls show
the new Horizontal Center.

Tip: If you are using the multi-zoom feature, all time-locked traces will pan together.
To pan at an accelerated rate, swipe the trace right/left or up/down.

Using MAUI

Zoom
To create a new zoom trace, touch then drag diagonally to draw a selection box around the portion of the
trace you want to zoom. Touch the Zx descriptor box to open the zoom factor controls and adjust the
zoom exactly.

To "zoom in" on any trace, unpinch two fingers over the trace horizontally.

To "zoom out" on any trace, pinch two fingers over the trace horizontally.

Note: Pinch gestures do not create a separate zoom (Zx) trace, they only adjust the Horizontal
Scale. When you pinch a channel (Cx) trace, the Timebase for all channels changes. If the trace is
the source of any other, all its dependent traces change, as well.

WaveRunner 8000 Oscilloscopes Instruction Manual

Turn Off
To turn off a trace, flick the trace descriptor box toward the bottom of the screen.

To turn off a measure parameter or Pass/Fail qualifier, flick the Px or Qx cell toward the bottom of the
screen. If it's the last active cell of the table, the table will close.

Using MAUI

Working With Traces
Traces are the visible representations of waveforms that appear on the display grid. They may show live
inputs (Cx, Digitalx), a math function applied to a waveform (Fx), a stored memory of a waveform (Mx), a
zoom of a waveform (Zx), or the processing results of special analysis software.
Traces are a touch screen object like any other and can be manipulated. They can be panned, moved,
labeled, zoomed, and captured in different visual formats for printing/reporting.
Each visible trace will have a descriptor box summarizing its principal configuration settings. See
OneTouch Help for more information about how you can use traces and trace descriptor boxes to modify
your configurations.

Active Trace
Although several traces may be open, only one trace is active and can be adjusted using front panel
controls and touch screen gestures. A highlighted descriptor box indicates which trace is active. All
actions apply to that trace until you activate another. Touch a trace descriptor box to make it the active
trace (and the foreground trace in that grid).

Active trace descriptor (left), inactive trace descriptor (right).

Whenever you activate a trace, the dialog at the bottom of the screen automatically switches to the
appropriate setup dialog.

Active descriptor box matches active dialog tab.

Foreground Trace
Since multiple traces can be opened on the same grid, the trace shown on top of the others is the
foreground trace. Grid indicators (matched to the input channel color) represent values for the foreground
trace.
Touch a trace or its descriptor box to bring it to the foreground. This also makes it the active trace.
Note that a foreground trace may not be the same as the active trace. A trace in a separate grid may
subsequently become the active trace, but the indicators on a given grid will still represent the foreground
trace in that group.

WaveRunner 8000 Oscilloscopes Instruction Manual

Turning On/Off Traces
Analog Traces
From the front panel, press the Channel button (1-4) to turn on the trace; press again to turn it off.
To turn on the trace from the touch screen, touch the Add New box and select Channel, or drag another
Channel (Cx) descriptor box to the Add New box.
To turn off a channel trace from the touch screen, do any of the following:
l

Flick the trace descriptor box toward the bottom of the screen.
Touch-and-hold (right-click) on the descriptor box until a white circle appears, then from the context
menu select Off.
Clear the "On" box on the Channel Setup or Cx dialogs.
Note: The default is to display each trace in its own grid. Use the Display menu to change how
traces are displayed.

Digital Traces
From the front panel, turn on the trace by pressing the Dig button, then checking Group on the Digitalx
trace dialog.
To turn on the trace from the touch screen, choose Vertical > Digitalx Setup then check Group on the
Digitalx dialog.
Clear the Group checkbox to turn off the trace, or flick the trace descriptor box toward the bottom of the
screen.

Other Traces
From the front panel, touch the Zoom button to create quick zooms of all open traces. Press the button
again to turn them off.
From the touch screen, touch the Add New box and select the trace type, or drag another descriptor box
of that type to the Add New box. Turn off the trace the same as you would a channel trace.

Adjusting Traces
To adjust Vertical Scale (gain or sensitivity) and Vertical Offset, just activate the trace and use the front
panel Vertical knobs. To make other adjustments—such as channel pre-processing or the math function
definition—touch the trace descriptor box twice to open the appropriate setup dialog.
Many entries can be made by selecting from the pop-up menu that appears when you
touch a control. When an entry field appears highlighted in blue after touching, it is active
and the value can be modified by turning the front panel knobs. Fields that don't have a
dedicated knob (as do Vertical Level and Horizontal Delay) can be modified using the
Adjust knob.

Using MAUI
If you have a keyboard installed, you can type entries in an active (highlighted) data entry field. Or, you can
touch again, then "type" the entry by touching keys on the virtual keypad or keyboard.
To use the virtual keypad, touch the soft keys exactly as you would a calculator. When you touch OK, the
calculated value is entered in the field.

Moving Traces
Use any of these methods to move traces from grid to grid. See OneTouch Help for ways to pan traces
within the same grid.

Drag-and-Drop
You can move a trace from one grid to another by dragging its descriptor box to the desired grid. This is a
convenient way to quickly re-arrange traces on the display.

If you are in Q-Scape display mode, you can drag the descriptor box to a grid on another tab, provided the
grid is visible while you are moving the trace. For example, you cannot drag descriptors across tabs in QScape Single mode, because the target grids aren't visible, but you can in Q-Scape Dual or Q-Scape
Mosaic modes. This is true even in extended display. For more information, see Display.

Next Grid Button
Touch twice on the descriptor box of the trace you want moved to open the setup dialog, then touch the
Next Grid action toolbar button at the bottom of the dialog. You can also touch and hold (right-click) the
trace descriptor box and choose Next Grid from the context menu.
Note: If only one grid is open, a second grid opens automatically when you select Next Grid.

WaveRunner 8000 Oscilloscopes Instruction Manual

Labeling Traces
The Label function gives you the ability to add custom annotations to the trace display. Once placed,
labels can be moved to new positions or hidden while remaining associated with the trace.

Create Label
1. Select Label from the context menu, or touch the Label Action toolbar button on the trace setup
dialog.

2. On the Trace Annotation pop-up, touch Add Label.
3. Enter the Label Text.
4. Optionally, enter the Horizontal Pos. and Vertical Pos. (in same units as the trace) at which to
place the label. The default position is 0 ns horizontal. Use Trace Vertical Position places the label
immediately above the trace.

Reposition Label
Drag-and-drop labels to reposition them, or change the position settings on the Trace Annotation pop-up.

Edit/Remove Label
On the Trace Annotation pop-up, select the Label from the list. Change the settings as desired, or touch
Remove Label to delete it.
Clear View labels to hide all labels. They will remain in the list.

Using MAUI

Zooming
Zooms magnify a selected region of a trace by altering the Horizontal Scale relative to the source trace.
Zooms may be created in several ways, using either the front panel or the touch screen. You can adjust
zooms the same as any other trace using the front panel Vertical and Horizontal knobs or the touch screen
zoom factor controls.
The current settings for each zoom trace can be seen on the Zx dialogs, while the Zoom dialog is a
convenient panel for turning on/off zooms or changing the zoom source.
The MultiZoom feature creates time-locked zoom traces for only the waveforms that you choose to
include. The zooms are of the same X-axis section of each waveform. As you scroll through a waveform,
all included zooms scroll in unison. For more information, refer to MultiZoom.

Zoom Dialog
Zoom controls appear throughout the X-Stream software wherever it is likely you may wish to change the
display scale of a trace, sometimes as a main dialog, sometimes as a subdialog, such as when setting up:
l

Math traces on Fx dialogs

Memory traces on Mx dialogs

To display the zoom controls, choose Math > Zoom Setup from the menu bar, or touch a zoom descriptor
box.
The main Zoom dialog contains selection boxes for turning on/off and changing the source of a zoom.
There are also options to:
l

Reset All, return all zooms to x1 magnification.
Quick Zoom, create a corresponding zoom trace for each open channel trace, same as using the
front panel Zoom button.
MultiZoom

WaveRunner 8000 Oscilloscopes Instruction Manual

Zx Dialog
Behind the main Zoom dialog is a separate tab for each potential zoom trace (Z1-Zx). Each Zx dialog
reflects the center and scale for that zoom. Use it to adjust the zoom magnification.

Trace Controls
Trace On shows/hides the zoom trace. It is selected by default when the zoom is created.
Source lets you change the source for this zoom to any channel, math, or memory trace while maintaining
all other settings.

Segment Controls
These controls are used in Sequence Sampling Mode.

Zoom Factor Controls
l

Out and In buttons increase/decrease zoom magnification and consequently change the Horizontal
and Vertical Scale settings. Touch either button until you've achieved the desired level.
Var.checkbox enables zooming in single increments.
Horizontal Scale/div sets the time represented by each horizontal division of the grid. It is the
equivalent of Time/div in channel traces, only unlike that setting, it may differ for each zoom trace.
Vertical Scale/div sets the voltage level represented by each vertical division of the grid; it's the
equivalent of V/div in channel traces.
Horizontal/Vertical Center sets the time/voltage at the center of the grid. The horizontal center is
the same for all zoom traces.
Reset Zoom returns the zoom to x1 magnification.

Using MAUI

Creating Zooms
Any type of trace can be "zoomed" by creating a new zoom trace (Zx) following the procedures here.
Note: On instruments with OneTouch, traces can be "zoomed" by pinching/unpinching two fingers
over the trace, but this method does not create a separate zoom trace. With channel traces,
pinching will alter the acquisition timebase and the scale of all traces. Create a separate zoom
trace if you do not wish to do this.
All zoom traces open in the next empty grid, with the zoomed portion of the source trace highlighted. If
there are no more available grids, zooms will open in the same grid as the source trace.

Zoomed area of original trace highlighted. Zoom in new grid below.

Quick Zoom
Use the front panel Zoom button to quickly create one zoom trace for each displayed channel trace.
Quick zooms are created at the same vertical scale as the source trace and 10:1 horizontal magnification.
To turn off the quick zooms, press the Zoom button again.

Manually Create Zoom
To manually create a zoom, touch-and-drag diagonally to draw a selection box
around any part of the source trace.
The zoom will resize the selected area to fit the full width of the grid. The degree
of vertical and horizontal magnification, therefore, depends on the size of the
rectangle that you draw.
Alternatively, you can drag any Zx descriptor box over the Add New box, or touch
the Add New box and choose Zoom from the pop-up menu. The next available
zoom trace opens with its Zx dialog displayed for you to modify scale as needed.
Finally, you can touch-and-hold (right-click) on the descriptor box of the trace you
wish to zoom until a white circle appears, then choose Math from the context
menu. Select the Zoom operator to create a zoom in the next open math function. This method creates a
new Fx trace, rather than a new Zx trace, but it can be rescaled in the same manner. It is a way to create
more zooms than you have Zx slots available on your instrument.

WaveRunner 8000 Oscilloscopes Instruction Manual

Adjust Zoom Scale
The zoom's Horizontal units will differ from the signal timebase because the zoom is showing a calculated
scale, not a measured level. This allows you to adjust the zoom factor using the front panel knobs or the
zoom factor controls however you like without affecting the timebase (a characteristic shared with math
and memory traces).

Close Zoom
New zooms are turned on and visible by default. If the display becomes too crowded, you can close a
particular zoom and the zoom settings are saved in its Zx slot, ready to be turned on again when desired.
To close the zoom, touch-and-hold (right-click) on the zoom descriptor box until the white circle appears,
then from the context menu choose Off.

MultiZoom
MultiZoom creates time-locked zoom traces for only the waveforms that you choose to include. The
zooms are of the same X-axis section of each waveform. As you scroll through a waveform, all included
zooms scroll in unison.

Set Up MultiZoom
1. Choose Math > Zoom Setup... to open the Zoom dialog, then touch the MultiZoom tab or
MultiZoom Setup... button.
2. On the MultiZoom dialog, check On.
3. Select all the traces that are In the MultiZoom group.

Scroll Waveforms
The Auto-Scroll controls appear at the right of the MultiZoom dialog. They work similarly to A/V controls to
allow you to continuously scroll all the selected zoom traces in time-locked steps from the beginning to the
end of the acquisition.

Using MAUI

Print/Screen Capture
The front panel Print button captures an image of the display and outputs it according to your Print
settings. It can be used to save a LabNotebook, create an image file of waveform traces, or send the
display to a networked printer, etc.
The Printer

icon at the right of the Print dialog will also execute your print setting.

Print may be used as a screen capture tool by going to File > Print Setup and selecting to print to File,
then choosing a graphical format and naming scheme with your Screen Image Preferences. Once
configured, just press the Print button or Printer icon, and optionally annotate the image.
You can also use the touch screen to generate a screen capture by choosing File > Save > Screen image
and touching Save Now at the right of the dialog. The file is saved using your latest Screen Image
Preferences settings.

WaveRunner 8000 Oscilloscopes Instruction Manual

Acquisition

Acquisition
The acquisition settings include everything required to produce a visible trace on screen and an acquisition
record that may be saved for later processing and analysis:
l

Vertical axis scale at which to show the input signal and probe characteristics that affect the signal,
such as attenuation and deskew time

Horizontal axis scale at which to represent time, and acquisition sampling mode and sampling rate

Acquisition trigger mechanism

Optional acquisition settings include bandwidth filters and pre-processing effects, vertical offset, and
horizontal trigger delay, all of which affect the appearance and position of the waveform trace.
To avoid aliasing and other waveform distortions, it is advisable (per Nyquist) to acquire at a sample rate at
least twice the bandwidth of the input signal. It can be shown that a sample rate 10 times the acquisition
bandwidth is preferable in order to over sample fast signal rise times consistent with the oscilloscope
bandwidth.
Those with higher speed acquisition systems may need to manually adjust Bandwidth, Time/div, Sample
Rate, and the number of Active Channels to achieve the optimal result. Most Teledyne LeCroy
oscilloscopes have a Fixed Sample Rate option, which uses whatever memory is required for the
acquisition time, until none remains.

Auto Setup
Auto Setup quickly configures the essential acquisition settings based on the first input signal it finds,
starting with Channel 1. If nothing is connected to Channel 1, it searches Channel 2 and so forth until it
finds a signal. Vertical Scale (V/div), Offset, Timebase (Time/div), and Trigger are set to an Edge trigger on
the first, non-zero-level amplitude, with the entire waveform visible for at least 10 cycles over 10 horizontal
divisions.
To run Auto Setup:
1. Either press the front panel Auto Setup button or choose Auto Setup from the Vertical, Timebase,
or Trigger menus. All these options perform the same function.
2. Press the Auto Setup button again or use the touch screen display to confirm Auto Setup.
After running Auto Setup, you'll see the words "Auto Setup" next to an Undo button at the far right of the
menu bar. This allows you to restore the settings in place prior to the Auto Setup.
Note: You will undo all new measurements or math function definitions entered since the Auto
Setup when you Undo the Auto Setup. Perform this work when the instrument is not in the Auto
Setup mode if you wish for it to persist.

WaveRunner 8000 Oscilloscopes Instruction Manual

Viewing Status
All instrument settings can be viewed through the various Status dialogs. These show all existing
acquisition, trigger, channel, math function, measurement and parameter configurations, as well as which
are currently active.
Access the Status dialogs by choosing the Status option from the Vertical, Timebase, Math, or Analysis
menus (e.g., Channel Status, Acquisition Status).

Vertical
Vertical, also called Channel, settings usually relate to voltage level and control input channel traces (C1Cx) along the Y axis.
Note: While Digital settings can be accessed through the Vertical menu on -MS model
instruments, they are handled quite differently. See Digital.
The amount of voltage displayed by one vertical division of the grid, or Vertical Scale (V/div), is most
quickly adjusted by using the front panel Vertical knob. The Cx descriptor box always shows the current
Vertical Scale setting.
Detailed configuration for each trace is done on the Cx dialogs. Once configured, channel traces can be
quickly turned on/off or modified using the Channel Setup dialog.

Channel Setup Dialog
Use the Channel Setup dialog to quickly make basic Vertical settings for all analog input channels. To
access the Channel Setup dialog, choose Vertical > Channel Setup from the menu bar.

To show/hide the channel trace, select/deselect the checkbox next the channel number.
To change the channel trace color, touch the color block next to the channel number, then choose the
new color from the pop-up menu.

Acquisition
To change any other Vertical settings, touch the input field and enter the new value.
On instruments with OneTouch, drag-and-drop the source channel descriptor box onto the target channel
descriptor box to copy settings from one channel to another
You can also touch Copy Channel Setup, then select the channel to Copy From and all the channels to
Copy To.

Cx (Channel) Dialog
Full vertical setup is done on the Cx dialog. To access it, choose Vertical > Channel <#> Setup from the
menu bar, or touch the Channel descriptor box.

The Cx dialog contains:
l

Vertical settings for scale, offset, coupling, bandwidth, and probe attenuation

Rescale settings

Pre-processing settings for pre-acquisition processes such as noise filtering and interpolation.

If a Teledyne LeCroy probe is connected, its Probe dialog appears to the right of the Cx dialog.

Vertical Settings
The Trace On checkbox turns on/off the channel trace.
Vertical Scale sets the gain (sensitivity) in the selected Vertical units, Volts by default. Select Variable
Gain for fine adjustment or leave the checkbox clear for fixed 1, 2, 5, 10-step adjustments.
Offset adds a defined value of DC offset to the signal as acquired by the input channel. This may be helpful
in order to display a signal on the grid while maximizing the vertical height (or gain) of the signal. A negative
value of offset will "subtract" a DC voltage value from the acquired signal (and move the trace down on the
grid") whereas a positive value will do the opposite. Touch Zero Offset to return to zero.
A variety of Bandwidth filters are available. To limit bandwidth, select a filter from this field.
Coupling may be set to DC 50 Ω, DC1M, AC1M or GROUND.
Caution: The maximum input voltage depends on the input used. Limits are displayed on the body
of the instrument. Whenever the voltage exceeds this limit, the coupling mode automatically
switches to GROUND. You then have to manually reset the coupling to its previous state. While the
unit does provide this protection, damage can still occur if extreme voltages are applied.

WaveRunner 8000 Oscilloscopes Instruction Manual

Probe Attenuation and Deskew
Probe Attenuation and Deskew values for third-party probes may be entered manually on the Cx dialog.
The instrument will detect it is a third-party probe and display these fields.
When a Teledyne LeCroy probe is connected to a channel input:
l

Passive probe Attenuation is automatically set, and this field is disabled on the Cx dialog.
For active voltage and current probes, a tab is added to the right of the Cx tab. The Attenuation field
becomes a button to access the Probe dialog. Enter Attenuation on the Probe dialog.

Pre-Processing Settings
Average performs continuous averaging or the repeated addition, with unequal weight, of successive
source waveforms. It is particularly useful for reducing noise on signals drifting very slowly in time or
amplitude. The most recently acquired waveform has more weight than all the previously acquired ones:
the continuous average is dominated by the statistical fluctuations of the most recently acquired
waveform. The weight of old waveforms in the continuous average gradually tends to zero (following an
exponential rule) at a rate that decreases as the weight increases.
Interpolate applies (Sinx)/x interpolation to the waveform. The selection of None applies Linear
interpolation, which inserts a straight line between sample points and is best used to reconstruct straightedged signals such as square waves. (Sinx)/x interpolation, on the other hand, is suitable for
reconstructing curved or irregular wave shapes, especially when the sample rate is 3 to 5 times the
system bandwidth. Choose an upsample factor of 2 or 45 points.
Note: 10 point Sinx/x interpolation can be set by sending the command via IEEE 488.2 remote
control or COM Automation.
Deskew adjusts the horizontal time offset by the amount entered in order to compensate for propagation
delays caused by different probes or cable lengths. The valid range is dependent on the current timebase
setting. The Deskew pre-processing setting and the Deskew math function perform the same action.
Noise Filter applies Enhanced Resolution (ERes) filtering to increase vertical resolution, allowing you to
distinguish closely spaced voltage levels. The tradeoff is reduced bandwidth. The functioning of the
instrument's ERes is similar to smoothing the signal with a simple, moving-average filter. It is best used on
single-shot acquisitions, acqusitions where the data record is slowly repetitive (and you cannot use
averaging), or to reduce noise when your signal is noticeably noisy but you do not need to perform noise
measurements. It also may be used when performing high-precision voltage measurements and zooming
with high vertical gain, for example. See Enhanced Resolution.
Invert inverts the trace.
Cable De-Embedding (available as an option) allows you to remove the effects of cables used in the test
setup. Select the checkbox, then enter the attenuation constants or cable characteristics (provided by the
cable manufacturer) on the Cable De-Embedding dialog that appears. See Cable De-Embedding.

Acquisition

Probe Dialog
The Probe Dialog immediately to the right of the Cx dialog displays the probe attributes and (depending on
the probe type) allows you to AutoZero, DeGauss and make tip selection for probes from the touch screen.
Other settings may appear, as well, depending on the probe model.
Caution: Remove probes from the circuit under test before initializing Auto Zero or DeGauss.

Auto Zero Probe
Auto Zero corrects for DC offset drifts that naturally occur from thermal effects in the amplifier of active
probes. Teledyne LeCroy probes incorporate Auto Zero capability to remove the DC offset from the
probe's amplifier output to improve the measurement accuracy.

DeGauss Probe
The Degauss control is activated for some types of probes (e.g., current probes). Degaussing eliminates
residual magnetization from the probe core caused by external magnetic fields or by excessive input. It is
recommended to always Degauss probes prior to taking a measurement.

Tip Select
If using one of the modular WaveLink probes, specify the type of tip/lead you're using by touching the Tip
Select control and making the appropriate selection.
Note: It's crucial to make the tip selection on this field as it results in the amplifier and tip
combination having the response calibrated for at the factory. Failure to do so may result in
inaccurate measurements.

WaveRunner 8000 Oscilloscopes Instruction Manual

Cable De-Embedding Option
Losses in the cables used in the test setup can reduce the accuracy of your signal (for example, signal
amplitude and risetime), as well as introduce Inter-Symbol Interference. These cable effects can
dramatically alter measurements and potentially create mask test violations.
Cable De-Embedding, available as an option, allows you to quickly specify the characteristics of the cables
(typically found on the cable's data sheet) in your test setup and analyze your signal with the effects of the
cables removed. The compensated signal is a more accurate representation of what was actually
transmitted.
When Cable De-Embedded is installed and selected from the channel pre-processing settings, the Cable
De-Embedding dialog will appear for you to describe the cable being used on the channel.

1. Touch Vertical > Channel # Setup... from the menu bar.
2. On the Cx dialog, check Cable De-Embeddingto display the Cable De-Embedding tab.
3. On the Cable De-Embedding dialog, touch Cable Specified by and choose either:
Attenuation Constants. Enter the cable loss model constants (provided by the manufacturer) in
Cable A1 and Cable A2.
Or
Attenuation Table. Enter the first set of Frequency and Attenuation values. Touch Add to continue
adding rows as needed.

To edit a row in the table, select the row, change values, then touch Change. To delete a row, select
the row and touch Delete.
4. Touch Delay Specified by and choose from Propagation Velocity, Nominal Delay, or Dielectric
Constant. Enter the value in the field of the same name.
5. Enter the Cable Length in inches.

Acquisition
6. Click Apply to initiate the cable de-embedding for the signal on this channel so that the effects of
the cable are removed.
7. To save this cable configuration for future use, touch File Name [DefaultCable] and enter a name,
or touch Browse and select a file to overwrite. To reload previously saved configurations, browse to
the file, then touch Load.

WaveRunner 8000 Oscilloscopes Instruction Manual

Digital (Mixed Signal)
The digital leadset (standard with -MS model oscilloscopes) inputs up-to-16 lines of digital data. Leads are
organized into two banks of eight leads each, and you assign each bank a standard Logic Family or a
custom Threshold to define the digital logic of the signal.
When a Mixed Signal input device is connected to the oscilloscope, digital input setup options are added to
the Vertical menu. There are four set up dialogs for each of four possible digital groups, which correspond
to buses: Digital1 to Digital4. You choose which lines make up each digital group, what they are named,
and how they appear on the display.

Digital Traces
When a digital group is enabled, digital Line traces (the Expanded view) show which lines are high, low, or
transitioning relative to the threshold. You can also view a digital Bus trace that collapses all the lines in a
group into their Hex values.

Four digital lines displayed with a Vertical Position +4.0 (top of grid) and a Group Height 4.0 (divisions).

Activity Indicators
Activity indicators at the bottom of the Digitalx dialogs show which lines are High (up arrow), Low (down
arrow), or Transitioning (up an down arrows) relative to the Logic Threshold value. They provide a quick
view of which lines are active and of interest to display on screen.

Collapse collapses the lines in a group into their Hex values.

3. In Vertical Position, enter the number of divisions (positive or negative) relative to the zero line of
the grid where the display begins.The top of the first trace appears at this position.
4. In Line Height, enter the total number of grid divisions each line should occupy.
The example above shows a group of four Expanded traces each occupying a Line Height of 1.0
division.
To close digital traces, uncheck the Trace On box on the Digitalx dialog.
Tip: Because a new grid opens to accommodate each enabled group, you may wish to enable
groups one or two at a time when they have many lines to maximize the total amount of screen
space available for each. Closing the set up dialogs will also increase available screen space.

Renaming Digital Lines
The labels used to name each line can be changed to make the user interface more intuitive.
1. Set up the digital group.
2. Touch the Line number field below the corresponding checkbox. If necessary, use the Left/Right
Arrow buttons to switch between banks.
3. Use the virtual keyboard to enter the new name, then press OK.
Any active line traces are renamed accordingly.

Acquisition

Timebase
Timebase, also known as Horizontal, settings control the trace along the X axis. The timebase is shared by
all channels.
The time represented by each horizontal division of the grid, or Time/Division, is most easily adjusted
using the front panel Horizontal knob. Full Timebase set up, including sampling mode and clock source
selection, is done on the Timebase dialog, which can be accessed by either choosing Timebase >
Horizontal Setup from the menu bar or touching the Timebase descriptor box.

Timebase Set Up
Use the Timebase dialog to select the sampling mode, memory and number of active channels. You can
also use it instead of the Front Panel to modify the Time/Div and horizontal Delay. There are related
dialogs for Clock Source.

Sampling Mode
Choose from Real Time, Sequence, RIS, or Roll mode.

Timebase Mode
Time/Division is the time represented by one horizontal division of the grid. Touch the Up/Down Arrow
buttons on the Timebase dialog or turn the front panel Horizontal knob to adjust this value. The overall
length of the acquisition record is equal to 10 times the Time/Division setting.
Delay is the amount of time relative to the trigger event to display on the grid. Raising/lowering the Delay
value has the effect of shifting the trace to the right/left. This allows you to isolate and display a
time/event of interest that occurs before or after the trigger event.
l

Pre-trigger Delay, entered as a negative value, displays the acquisition time prior to the trigger event,
which occurs at time 0 when in Real Time sampling mode. Pre-trigger Delay can be set up to the
instrument's maximum sample record length; how much actual time this represents depends on the
timebase. At maximum pre-trigger Delay, the trigger position is off the grid (indicated by the arrow at
the lower right corner), and everything you see represents 10 divisions of pre-trigger time.
Post-trigger Delay, entered as a positive value, displays time following the trigger event. Post-trigger
Delay can cover a much greater lapse of acquisition time than pre-trigger Delay, up to the equivalent
of 10,000 divisions after the trigger event occurred (it is limited at slower time/div settings and in Roll
mode sampling). At maximum post-trigger Delay, the trigger point is off the grid far left of the time
displayed.

Set to Zero returns Delay to zero.

WaveRunner 8000 Oscilloscopes Instruction Manual

Real Time Sampling Rate
These controls specify how the instrument samples when in Real Time mode.
Maximum Sample Points is the number of samples taken per acquisition when you choose to Set
Maximum Memory. It changes to show Sampling Rate, the number of samples taken per time division,
when using a Fixed Sampling Rate.
Set Maximum Memory, the default setting on MAUI oscilloscopes, automatically adjusts the sampling
rate to take the maximum number of samples possible given the amount of pre- or post-trigger Delay and
the Time/div, up to the maximum record length. This optimizes the sample rate for fast timebases when in
Real Time mode.
Fixed Sampling Rate activates the Sampling Rate field for you to set your own rate. Lowering the rate
can extend the acquisition to accommodate slower timebases or longer delays.

Active Channels (Dual-Channel Acquisition)
The Active Channels settings allow you to combine the acquisition capabilities of the leftmost pair of
channels (C1 and C2) and the rightmost pair of channels (C3 and C4) to result in two channels with
maximum sample rate and memory.
In 4-channel mode, all channels remain active at the default sample rate ().
To combine channels, under Active Channels, choose 2 or Auto:
l

2-channel mode turns off waveform acquisition on Channels 1 and 4, although they can still be used
for trigger input. Channels 2 and 3 acquire at doubled sample rate and memory ().
In Auto mode, the oscilloscope will allot the maximum memory and sample rate possible based on
the activity within each pair of channels. As long as only one channel in each of the C1-C2 and C3-C4
pairs is turned on, the maximum rate is used. Turning on both channels in either pair has the same
effect as selecting 4 Active Channels.

Example: In Auto mode, C1 can operate with either C3 or C4 at higher sample rate and memory
since they belong to different pairs, and likewise C2. However, C1 cannot operate with C2 without
dropping the sample rate, nor can C3 operate with C4.
Refer to Acquisition System in the product datasheet for maximum sample rates.

Sampling Modes
The Sampling Mode determines how the instrument samples the input signal and renders it for display.

Real Time Sampling Mode
Real Time sampling mode is a series of digitized voltage values sampled on the input signal at a uniform
rate. These samples are displayed as a series of measured data values associated with a single trigger
event. By default (with no Delay), the waveform is positioned so that the trigger event is time 0 on the grid.
The relationship between sample rate, memory, and time can be expressed as:
Capture Interval = 1/Sample Rate X Memory
Capture Interval/10 = Time Per Division
52

Acquisition
Usually, on fast timebase settings, the maximum sample rate is used when in Real Time mode. For slower
timebase settings, the sample rate is decreased so that the maximum number of data samples is
maintained over time.

Roll Sampling Mode
Roll mode displays, in real time, incoming points in single-shot acquisitions that appear to "roll"
continuously across the screen from right to left until a trigger event is detected and the acquisition is
complete. The parameters or math functions set on each channel are updated every time the roll mode
buffer is updated as new data becomes available. This resets statistics on every step of Roll mode that is
valid because of new data.
Timebase must be set to 100 ms/div or slower to enable Roll mode selection. Roll mode samples at ≤ 5
MS/s. Only Edge trigger is supported.
Note: If the processing time is greater than the acquire time, the data in memory is overwritten. In
this case, the instrument issues the warning, "Channel data is not continuous in ROLL mode!!!" and
rolling starts again.

RIS Sampling Mode
RIS (Random Interleaved Sampling) allows effective sampling rates higher than the maximum single-shot
sampling rate. It is available on timebases ≤ 10 ns/div.
The maximum effective RIS sampling rate is achieved by making multiple single-shot acquisitions at
maximum real-time sample rate. The bins thus acquired are positioned approximately 5 ps (200 GS/s)
apart. The process of acquiring these bins and satisfying the time constraint is a random one. The relative
time between ADC sampling instants and the event trigger provides the necessary variation.
Because the instrument requires multiple triggers to complete an acquisition, RIS is best used on
repetitive waveforms with a stable trigger. The number depends on the sample rate: the higher the sample
rate, the more triggers are required. It then interleaves these segments (as shown in the following
illustration) to provide a waveform covering a time interval that is a multiple of the maximum single-shot
sampling rate. However, the real-time interval over which the instrument collects the waveform data is
much longer, and depends on the trigger rate and the amount of interleaving required.
Note: RIS is not available when the oscilloscope is operating in fixed sample rate Mode.

Sequence Sampling Mode
In Sequence Mode sampling, the completed waveform consists of a number of fixed-size segments. The
instrument uses the Timebase Sequence settings to determine the capture duration of each segment.
The desired number of segments, maximum segment length, and total available memory are used to
determine the actual number of samples or segments, and time or points.
Sequence Mode is ideal when capturing many fast pulses in quick succession or when capturing few
events separated by long time periods. The instrument can capture complicated sequences of events
over large time intervals in fine detail, while ignoring the uninteresting periods between the events.
Measurements can be made on selected segments using the full precision of the timebase.

WaveRunner 8000 Oscilloscopes Instruction Manual
Sequence Mode Set Up
The Sequence dialog appears only when Sequence Mode sampling is selected. Use it to define the
number of fixed-size segments to be acquired in single-shot mode.

1. From the menu bar, choose Timebase > Horizontal Setup..., then Sequence Sampling Mode.
2. On the Sequence tab under Acquisition Settings, enter the Number of Segments to acquire.
Note: The number of segments displayed can be less than the total number acquired.
3. To stop acquisition in case no valid trigger event occurs within a certain timeframe, check the
Enable Timeout box and provide a Timeout value.
Note: While optional, Timeout ensures that the acquisition completes in a reasonable
amount of time and control is returned to the operator/controller without having to
manually stop the acquisition, making it especially useful for remote control applications.
4. Touch Display mode and select a sequence display mode from the pop-up menu:
Adjacent

Overlay

Waterfall (cascaded)

Perspective

Mosaic (tiled)

5. Touch one of the front panel Trigger buttons to begin acquisition.

Acquisition
Tip: You can interrupt acquisition at any time by pressing the front panel Stop button. In this
case, the segments already acquired will be retained in memory.
View Sequence Segments
When in Sequence sampling mode, you can view individual segments easily using the front panel Zoom
button. A new zoom of the channel trace defaults to Segment 1.
You can view other segments by changing the First and total Num(ber) of segments to be shown on the
Zx dialog. Touch the Zx descriptor box to display the dialog.
Tip: By setting the Num value to 1, you can use the front panel Adjust knob to scroll through each
segment in order.
Channel descriptor boxes indicate the total number of segments acquired in sequence mode. Zoom
descriptor boxes show the first segment displayed and total number of segments displayed ([#] #). As with
all other zoom traces, the zoomed segments are highlighted on the source trace.

Example: You have acquired 10 segments. You choose to display segments 4 to 6—or, a total of 3
segments beginning with segment 4. The Cx descriptor box reads 10. The Zx descriptor box reads
[4]3, meaning you are displaying a total of 3 segments, starting with segment 4.
Besides using the Zoom feature, you can also create a Math (Fx) trace to display individual segments.
1. From the menu bar, choose Math > Math Setup...
2. Touch a Function (Fx) tab to display its corresponding dialog.
3. On the dialog, touch Operator1 and select the Segment button from the pop-up menu.
4. Touch the Select subdialog tab.
5. Touch First Selected and choose the first segment to display.
6. Touch Number of Selected and enter the total number of segments to display.
To view time stamps for each segment:
1. From the Sequence dialog, choose Show Sequence Trigger Times.
Or
From the menu bar, choose Timebase > Acquisition Status, then open Trigger time .
2. Under Show Status For, choose Time.

WaveRunner 8000 Oscilloscopes Instruction Manual

Clock Source Settings
An external reference clock, applied via the REF In input, is used to synchronize the instrument's internal
timebase to an external frequency source. This allows multiple instruments to lock their timebases to a
common source.
An external sampling clock, applied via the EXT input, replaces the internal timebase as the sampling
clock. This means that the external sampling clock controls when the digitizers sample the input
waveforms.
Since the external sampling clock uses the EXT input, an external trigger cannot be used when the
external sampling clock is in use.

Clock Frequencies
The signal types, frequency ranges, and levels accepted for an external reference clock or sampling clock
are model dependent. See the product specifications at teledynelecroy.com.

Reference Clock
The default setting is to use the instrument's Internal 10 MHz clock. To use an external reference clock:
1. Connect a clock source to the Ref In 10 MHz input using a BNC cable.
2. Go to Timebase > Horizontal Setup and choose Real-Time Sampling Mode.
3. On the Clock Source tab under Reference Clock choose External.

Sample Clock
The default setting is to use the instrument's Internal clock. To use an external sample clock:
1. Connect a clock source to the EXT input using a BNC cable.
2. Go to Timebase > Horizontal Setup and choose Real-time Sampling Mode.
3. On the Clock Source tab under Sample Clock choose from 0V, ECL, or TTL pulse types.
4. Choose an External Coupling that matches the clock source input impedance.

Acquisition

History Mode
History Mode allows you to review any acquisition saved in the history buffer, which automatically stores
all acquisition records until full. Not only can individual acquisitions be restored to the grid, you can "scroll"
backward and forward through the history at varying speeds to capture individual details or changes in the
waveforms over time.
Each record is indexed and time-stamped, and you can choose to view the absolute time of acquisition or
the time relative to when you entered History Mode. In the latter case, the last acquisition is time zero, and
all others are stamped with a negative time. The maximum number of records stored depends on your
acquisition settings and the total available memory.
Press the front panel History Mode button, or choose Timebase > History Mode to access this feature.
Entering History Mode automatically stops new acquisitions. To leave History Mode, press the History
Mode button again, or restart acquisition by pressing one of the front panel Trigger Mode buttons.
Note: History Mode does not work with Sequence Mode acquisitions, pre-processor Interpolation
set on the input channel, or channel interleaving.

WaveRunner 8000 Oscilloscopes Instruction Manual

Replay Acquisition History
This is a good way to begin using History Mode. Watching a "movie" of the history allows you to see
waveform changes that are invisible during real-time acquisition.
Select View History to enable the display, then use the Navigation buttons or the slider bar at the bottom
of the dialog to "scroll" the history of acquisitions.
l

The top row buttons scroll: Fast Backward, Slow Backward, Slow Forward, Fast Forward.
The bottom row buttons step: Back to Start, Back One, Go to Index (row #), Forward One, Forward to
End.

Press Pause when you see something of interest, then use the History table to find the exact Index.

Select Single Acquisition
1. Select View History to enable the display, and View Table to show the index of records.
2. Optionally, select to show Relative Times on the table.
3. View individual acquisitions by selecting the row from the table or entering its Index number on the
dialog.

Acquisition

Trigger
Triggers define the event around which digitized information is displayed on the grid.
Different Trigger Types are used to select different events in the trigger source waveforms: edge voltages,
pulse widths, high/low states, etc. These may be a single channel event or a complex pattern of events
across several channels. On instruments with Mixed Signal capabilities, many triggers can be set on either
analog channels, including the External Trigger input, or digital lines.
In addition to the type, the Trigger Mode determines how the instrument behaves as it encounters trigger
events: take a single acquisition and stop, holding on to the display of the last acquisition, or continuously
take and display acquisitions.
In both cases, when the previous acquisition has completed processing, the oscilloscope is again ready to
acquire and the READY indicator is lit. If, while READY, the trigger circuit detects a signal that matches the
trigger conditions, the oscilloscope triggers on the next matching event, and the TRIG'D indicator is lit.
Unless modified by a pre- or post-trigger Delay, the trigger event appears at time 0 at the horizontal center
of the grid, and a period of time equal to five divisions of the timebase is shown to the left and right of it.
Delay shifts the trigger position on screen, displaying a different portion of the pre- or post-trigger
waveform.
An additional condition of Holdoff by time or events is available for Edge and Pattern triggers, including
those that appear within MultiStage triggers. Holdoff arms the trigger on the first matching event, inserts
the holdoff count, then triggers on a subsequent event. Often, especially with repetitive signals, the initial
arming event appears to the left of the trigger in "negative" acquisition time.

Trigger Modes
The Trigger Mode determines how often the instrument acquires. It is equivalent to how analog
oscilloscopes "sweep," or refresh, the display. Trigger Mode can be set from the Trigger menu or from the
front panel Trigger control group.
In Single mode, when you choose Trigger > Single or press the front panel Single button, the oscilloscope
readies, arms, and triggers provided all trigger conditions (including Holdoff) are met. It then stops and
continues to display the last acquisition until a new one is taken. The oscilloscope remains armed unless
manually stopped or triggered, and if a valid trigger does not occur, invoking Single a second time will force
a trigger and display the acquisition.
In Normal mode, operation is the same as in Single, except that the trigger automatically re-arms after the
previous acquisition is complete, and data is continuously refreshed on the touch screen.
Auto operates the same as Normal mode, except that a trigger is forced if the trigger event has not
occurred within a preset timeout period.
Stop ceases acquisition processing until you select one of the other three modes. The arming and Holdoff
counters are cleared, even if there has not yet been a trigger since the previous acquisition.

WaveRunner 8000 Oscilloscopes Instruction Manual

Trigger Types
The Trigger Type sets the triggering conditions. Special MultiStage types allow one set of conditions for
arming and another (same or different) set for triggering.
If a type is part of a subgroup (e.g., Smart), first choose the subgroup to display all the trigger options.

Basic Types
Edge triggers upon a achieving a certain voltage level in the positive or negative slope of the waveform.
Width triggers upon finding a positive- or negative-going pulse width when measured at the specified
voltage level.
Pattern triggers upon a user-defined pattern of concurrent high and low voltage levels on selected inputs.
In Mixed-Signal oscilloscopes, it may be a digital logic pattern relative to voltage levels on analog channels,
or just a digital logic pattern omitting any analog inputs. Likewise, if your oscilloscope does not have MixedSignal capability, the pattern can be set using analog channels alone.
TV triggers on a specified line and field in standard (PAL, SECAM, NTSC, HDTV) or custom composite
video signals.
Serial triggers on the occurrence of user-defined serial data events. This type will only appear if you have
installed protocol-specific serial data trigger and decode options.
Measurement is not technically a trigger, per se, but permits the instrument to stop and display acquisition
based on a post-processing measurement result, similar to a trigger.

MultiStage Types
MultiStage triggers establish dependencies between two or more distinct events, some that "qualify" or
arm, and others that trigger. The individual events are defined exactly as are the basic types (Edge, Width,
Pattern, etc.).
Cascaded establishes a succession of criteria in Stages A-D. The trigger occurs when stages B through
D—or whatever is the last defined event—are achieved. In Normal trigger mode, it automatically resets
after finding the last defined event. You may apply additional Holdoff by time or number of events between
each stage in the cascade.
QualFirst arms the oscilloscope on the A event, then triggers on all subsequent B events, saving each as a
Sequence Mode segment.
Note: This trigger is only enabled when using Sequence sampling mode.
Qualified arms on the A event, then triggers on the B event. In Normal trigger mode, it automatically resets
after the B event, and re-arms upon the next matching A event.
Note: This functionality is identical to Teledyne LeCroy's previous Qualify and State triggers, but
presented through a different user interface.

Acquisition

Smart Triggers
Smart triggers allow you to apply Boolean logic conditions to the basic signal characteristics of level, slope,
and polarity to determine when to trigger.
Glitch triggers upon finding a pulse-width that is less than a specified time or within a specified time range.
Window triggers when a signal enters or exits a window defined by voltage thresholds.
Interval triggers upon finding a specific interval, the time (period) between two consecutive edges of the
same polarity: positive to positive or negative to negative. Use the interval trigger to capture intervals that
fall short of, or exceed, a specified range.
Dropout triggers when a signal loss is detected. The trigger is generated at the end of the timeout period
following the last trigger source transition. It is used primarily in Single acquisitions with pre-trigger Delay.
Runt triggers when a pulse crosses a first threshold, but fails to cross a second threshold before recrossing the first. Other defining conditions for this trigger are the edge (triggers on the slope opposite to
that selected) and runt width.
SlewRate triggers when the rising or falling edge of a pulse crosses an upper and a lower level. The pulse
edge must cross the thresholds faster or slower than a selected period of time.

Trigger Set Up
To access the Trigger setup dialog, press the front panel Trigger Setup button or touch the Trigger
descriptor box.
Different controls will appear depending on the Trigger Type selected (e.g., Slope for Edge triggers).
Complete the settings shown after making your selection.
The trigger condition is summarized in a preview window at the far right of the Trigger dialog. Refer to this
to confirm your selections are producing the trigger you want.

Source
For most triggers, the Source is the analog channel or digital line to inspect for the trigger conditions.
Tip: When triggering on analog channels, the source can be easily set by dragging the desired
source channel descriptor box onto the Trigger descriptor box. Note that the trigger coupling and
slope/polarity will revert to whatever was last set on that channel.
Pattern triggers may utilize multiple sources (such as a mix of analog and digital signals), and likewise
MultiStage triggers may use different sources for the arming and triggering events.

WaveRunner 8000 Oscilloscopes Instruction Manual

Coupling
For analog triggers, specify the type of signal Coupling at the input.
l

DC - All the signal’s frequency components are coupled to the trigger circuit for high frequency bursts
or where the use of AC coupling would shift the effective trigger level.
AC - The signal is capacitively coupled. DC levels are rejected, and frequencies below 50 Hz are
attenuated.
LFREJ - The signal is coupled through a capacitive high-pass filter network, DC is rejected and signal
frequencies below 50 kHz are attenuated. For stable triggering on medium to high frequency signals.
HFREJ - Signals are DC coupled to the trigger circuit, and a low-pass filter network attenuates
frequencies above 50 kHz (used for triggering on low frequencies).

Slope/Polarity
For some triggers, such as Edge, you will be asked to select the waveform Slope (rising vs. falling) on
which the triggering event may occur.
For others, such as Width, the equivalent selection will be Polarity (positive vs. negative).

Level
For analog triggers, enter the voltage Level at which the triggering condition must occur. Use the Find
Level button to set the level to the signal mean.
Trigger types that require multiple crossings to define the triggering condition—such as Window, SlewRate
and Runt— will have Upper Level and Lower Level fields.
For digital triggers, the level is determined by the Logic Family that is set on the digital group. This can also
be specified by a custom (User-Defined) crossing Threshold and Hysteresis band. Usually, there will be a
separate Logic dialog tab for these triggers.

Hysteresis
For Edge triggers, you may select to Optimize for HF. When this box is unchecked, the trigger circuit's
hysteresis is set quite high to eliminate any potential trigger instability from high-frequency noise riding on
a low-frequency input signal. Because HF signal amplitudes tend to be smaller, the Optimize for HF setting
reduces the hysteresis value to make the trigger more sensitive. The effect this will have on trigger
behavior depends on the signal's spectral and noise content rather than just fundamental frequency, so it's
overall effect is difficult to quantify.

Conditions (Smart Triggers)
Smart triggers all allow you to apply Boolean logic to refine the triggering condition beyond simply Level
and Slope/Polarity.
The values that satisfy the operators of Less Than, Less Than or Equal To, Greater Than, etc. can be set
by entering an Upper Value and/or Lower Value.

Acquisition

In some cases, it is possible to set a range of values that satisfy the condition. The values may be In Range
that is bounded by the upper/lower values or Out Range.
The extent of the range can often also be specified by using a Nominal and Delta value, rather than an
absolute upper and lower value. In this case, the Nominal value sets the center of the range, and the Delta
determines how many units plus/minus the Nominal value are included in the range.
For Dropout triggers, the default is to Ignore Opposite Edge, setting the trigger to dropout of the Positive
or Negative edge within the given timeframe. Deselecting it has the effect of setting the trigger to dropout
on Both edges.

Patterns
A triggering pattern of low/high states across multiple inputs is used by the Pattern type and MultiStage
types that include Patterns as either the arming or triggering event. Patterns may be set on analog
channels, digital lines, or a combination or both when Mixed-Signal capabilities are available.
Digital Pattern

The Logic Bus method simplifies pattern set up by utilizing digital groups and logic you have already
defined on the Digital Setup dialogs. A digital pattern is set on a single bus (group) manually or by applying
a hexadecimal value, while the remaining lines are disabled ("Don't Care").
If you have not set up digital groups, you can set a digital pattern line by line using the Logic method. All
available lines remain active for selection.
1. On the Trigger dialog, select Pattern trigger type. Open the Digital Pattern dialog.

2. At the far right of the dialog, choose either Logic Bus or Logic.
3. Optionally, deselect Filter Out Unstable Conditions. This default filter ignores short glitches in logic
state triggers that last less than 3.5 ns.
4. If using Logic Bus, touch Source and select the digital group. Any lines that are not in this group will
now be disabled.
5. To apply a digital logic pattern, either:
l

Enter the hexadecimal value of the pattern in Hex or Value. Lines will take a logical 1, 0, or X
("Don't Care") according to the pattern. Disabled lines will remain X.
Touch the Dx button for each active line, and select whether it must be High or Low compared
to the logic threshold. Depending on your selection, a logical 1 (High) or 0 (Low) now appears
on the dialog. Leave X selected for any line you wish to exclude from the pattern. Use the Left
and Right Arrow buttons to display lines in other digital banks.

WaveRunner 8000 Oscilloscopes Instruction Manual
Note: As an alternative to a pattern, you may set edge conditions on any line. Touch the Dx
button and choose the edge. Edge conditions always assume a logical OR in the overall
trigger criteria.
As you work, the checkboxes along the bottom of the dialog will change to show the pattern. You
can also use these checkboxes to make selections.
6. If you have not already set a logic threshold, open the Levels dialog and select a Logic Family for
each digital bank from which you've selected lines. To set a custom logic threshold, choose Logic
Family User Defined, then enter the Threshold voltage and Hysteresis.
Note: Digital lines inherit the Logic Setup made when defining digital groups. However, you
can change the logic threshold on the Levels dialog. The two settings are linked and always
reflect whatever was last selected. Logic thresholds can only be set per lead bank, not
individual line.
Analog Pattern

Tip: With the Mixed-Signal option, you can also use the Digital Pattern dialog to set an analog state
pattern. Touch Set All To... and select Don't Care. This will eliminate any meaningful digital pattern
and activate all the Boolean operators. Use the Left Arrow button to display the C1-EXT group of
inputs, and follow the procedure below to set the low/high pattern on each input.
1. On the Trigger dialog, select the Pattern trigger type.

2. Select the Boolean Operator (AND, NAND, OR, or NOR) that describes the relationship among
analog inputs (e.g., C1 must be High AND C2 must be Low).
3. For each input to be included in the trigger pattern, select what State it must be in (High, Low, or
Don't Care) compared to the threshold Level you will set. Leave "Don't Care" selected for any input
you wish to exclude.
4. For each input included in the trigger, enter the voltage threshold Level.
5. If you've included EXTERNAL as an input, open the Ext tab and enter the external trigger
Attenuation.

Acquisition

MultiStage Triggers
MultiStage types arm on the A event, then trigger on a subsequent event. The options for the triggering
event depend on the type of arming event.
See Cascaded, QualFirst and Qualified.

Measurement Trigger
Measurement is not technically a trigger, but permits the instrument to stop and display acquisition based
on a post-processing measurement result, similar to a trigger. The available measurements depend on
your model instrument and the options installed, and each will offer a different method for specifying the
"trigger" conditions, based on the type of measurement. Generally, you will be able to specify a triggering
value or range of values, and for @level parameters, the voltage level at which the measurement is taken.
A measurement can be defined as a standalone trigger condition or as the final condition in a multistage
Cascaded trigger.

TV Trigger
TV triggers on a specified line and field in standard (PAL, SECAM, NTSC, HDTV) or custom composite
video signals.

1. Choose the Source signal input.
2. Choose the signal TV Standard. To use a custom signal, also enter the Frame Rate , # of Fields per
line, # of Lines, and Interlace ratio.
3. Choose the Line and Field upon which to trigger.

WaveRunner 8000 Oscilloscopes Instruction Manual

Serial Trigger
The Serial trigger type will appear if you have installed serial data trigger and decode options. Select the
Serial type then the desired Protocol to open the serial trigger setup dialogs. For setup instructions, see
the software instruction manual at teledynelecroy.com/support/techlib under Manuals > Software
Options.
Note: Certain software serial triggers can only be input on certain channels; the set up dialog will
instruct you which channel to use. A 3.125 Gb/s Serial Trigger hardware option is available for
WaveRunner oscilloscopes. This option provides capability for 8b/10b symbol triggering. The
trigger hardware is factory installed and is permanently connected internally to C4. Complete
information on the operation of the hardware serial trigger can be obtained in the High Speed Serial
Triggers Instruction Manual.

Acquisition

Qualified Trigger
A Qualified trigger arms on the A event, then triggers on the B event. In Normal trigger mode, it
automatically resets after the B event, and re-arms upon the next matching A event. Unlike a basic Edge or
Pattern trigger with Holdoff, the A and B events can occur in different signals, allowing you to use the state
of one signal to "qualify" the trigger on another.
On the Trigger dialog, select MultiStage > Qualified trigger type to display the controls.
On the Trigger dialog, select MultiStage trigger type and choose Qualified.

On the Qualified dialog, choose the A and B events.

Besides an Edge or Pattern, two special conditions may be selected as the arming event (A):
l

State, an analog or digital High/Low state ocurring on a single input.

PatState, a pattern of analog or digital High/Low states across multiple inputs.

When B is an Edge or Pattern, a time window may be added to the trigger conditions by using the When B
Occurs buttons:
l

Any Time triggers if B occurs any time after being qualified by A.

Less Than triggers only if B occurs before the time set once qualified.

Greater Than triggers only if B occurs after the time set once qualified.

Events triggers on the next B event after the specified N Events once qualified.

As with regular Holdoff, the counter may begin from the Acquisition Start or the Last Trigger Time.
Once you've selected the A and B events on the Qualified dialog, set up the conditions on the respective
"Event" dialogs exactly as you would a single-stage trigger.

WaveRunner 8000 Oscilloscopes Instruction Manual

QualFirst Trigger
The QualFirst trigger, which is used in Sequence sampling mode, is set up exactly like the Qualified trigger.
The only difference is that the "B" event is captured as a series of sequence segments, rather than a single
acquisition.

Cascaded Trigger
A Cascaded trigger type establishes a succession of criteria in Stages A-D. The trigger occurs when
stages B through D—or whatever is the last defined event—are achieved. In Normal trigger mode, it
automatically resets after finding the last defined event. You may apply additional Holdoff by time or
number of events between each stage in the cascade.
On the Trigger dialog, select MultiStage trigger type and choose Cascaded.

Then, on the Cascaded dialog choose the A through D events.

You may apply additional Holdoff at each stage by time or number of events:
l

Time and Events work exactly as they do in other Holdoff counts.
Time & Reset sets a Holdoff time between cascaded events, but resets to the beginning of the
cascade if no valid trigger occurs before the reset time expires.

Once you've selected the A through D events on the Cascade dialog, set up the conditions on the
respective sub-dialogs exactly as you would a single-stage trigger.

Acquisition

Trigger Holdoff
Holdoff is either a period of time or an event count that may be set as an additional condition for Edge and
Pattern triggers. Holdoff disables the trigger temporarily, even if the other conditions are met. Use Holdoff
to obtain a stable trigger for repetitive, composite waveforms. For example, if the number or duration of
sub-signals is known, you can disable them by setting an appropriate Holdoff value.
Note: Qualified operates using time or event conditions similar to Holdoff, but arm and trigger
differently.

Hold Off by Time
This is a period of time to wait after the arming event before triggering on the next event. The maximum
allowed time is 20 seconds; the Holdoff time would otherwise be limited only by the input signal, the
coupling, and the instrument's bandwidth.
When a Holdoff by time is counted from the start of the acquisition, the oscilloscope readies, arms on the
first event, holds for the specified time, then triggers on the next event. After one full acquisition has
completed, the oscilloscope again readies, arms, holds, and triggers for the following acquisition.

Positive Edge trigger with Holdoff by time counted from the start of acquisition.

When a Holdoff by time is counted from the last trigger time, the oscilloscope immediately re-arms on the
first event following the trigger and begins counting the Holdoff, rather than wait to complete the full
acquisition. The Holdoff count continues even during the very brief time between acquisitions while the
oscilloscope is processing. As soon as the Holdoff is satisfied and the oscilloscope is again ready, it triggers
on the next event. The re-arming and Holdoff may occur in one acquisition, and the trigger in the next.

Positive Edge trigger with Holdoff by time counted from the last trigger time.

WaveRunner 8000 Oscilloscopes Instruction Manual
Note: Because there is only one trigger per acquisition, the trigger event will always belongs to the
new acquisition. The processing time shown here is for purposes of illustration only.
Regardless of where in the acquisition record the trigger event was found (first edge or last), the display
will show time pre- and post-trigger based on your Time/Div and Delay settings.

Hold Off by Events
Events refers to the number of times the trigger conditions have been met following the arming event.
For example, if the Holdoff is two edges counted from the start of the acquisition, the oscilloscope readies,
arms on the first edge, holds off for the next two, triggers on the fourth edge, then completes the
acquisition. Because there must always be a first arming edge, the Holdoff appears to be "Holdoff plus
one."

Positive Edge trigger with Holdoff by events counted from start of acquisition.

As with Holdoff by time, when a Holdoff by events is counted from the last trigger time, the oscilloscope rearms immediately following the trigger and begins the Holdoff count. If the count is satisfied by the time
the oscilloscope is again ready, the trigger occurs on the next event at the start of the new acquisition.

Software Assisted Trigger
Software Assisted Trigger is used to find the trigger-level crossing point closest to the hardware trigger
point. It then adjusts the time offset of the waveform so that it is aligned with the specified trigger level
and slope.
In the following figure, the white trace is the waveform at the input to software-assisted trigger
processing. The red trace shows it after processing, aligned with the trigger point indicated by the red
marker below the grid.

Note: This feature can only be used with an Edge trigger type in Normal trigger mode.
1. From the menu, choose Triggers > Trigger Setup, then touch the Software Assisted Trigger tab.

2. Touch Enable.
3. Create a trigger window by entering a Hysteresis value. This value sets a boundary above and
below the main trigger level to exclude noise.
4. Choose Auto or Normal mode; this determines the trigger behavior when trigger crossings are not
found in the trigger source waveform.
l
l

Auto mode allows all waveforms through the channel.
Normal mode allows waveforms only with a trigger crossing within the horizontal gate region
through the channel.

5. Set Start and Stop time values on the Horizontal Gate part of the Software Assisted Trigger tab.
These values control where in the waveform the software-assisted trigger processing searches for
trigger crossings.

Acquisition

TriggerScan
TriggerScan is a debugging tool that helps you quickly discover waveform anomalies by automating the
process of building triggers designed to find rare events in an acquisition. TriggerScan:
l

Trains the system by looking at normal acquired waveforms. During the training, TriggerScan
analyzes the waveforms to determine what waveforms normally look like. Using this information, it
generates a list of smart triggers to isolate abnormal situations.
Loads the trigger setups from the Trainer and cycles them. As triggers occur, they are overlaid on the
screen. All acquisition settings are preserved, and you can use other tools to find the root cause of
these anomalies such as WaveScan, Histograms, etc.

Training TriggerScan
The TriggerScan Trainer inspects the current acquisition and automatically builds a list of trigger setups
that could potentially be used to find events of interest.
Note: Run the Trainer if you want to change the trigger types or if you change the channel or
signal. You must acquire and display at least 3 cycles of a signal before running the Trainer.
1. Touch Trigger > Trigger Setup... from the menu bar, then open the TriggerScan tab.
2. Touch the Trainer button.
3. On the TriggerScan Trainer pop-up, choose the Source channel on which to train and trigger, and
select all the trigger types you want to set up.
4. Touch the Start Training button. When training is complete, a list of smart trigger setups is
displayed in the Trigger List.

Modifying Trigger List
Follow these steps to change the triggers created by TriggerScan. Once you have finalized the Trigger
List, you are ready to start scanning.
1. Choose Trigger > Trigger Setup... from the menu bar, then open the TriggerScan tab.

2. Make any of the following modifications to the Trigger List:
l

Add new trigger: touch the Trigger descriptor box and set up the new trigger as desired on the
Trigger dialog. Then, back on the TriggerScan dialog, touch the Add New button to append
the new trigger to the Trigger List.

WaveRunner 8000 Oscilloscopes Instruction Manual
l

Replace a trigger with one manually set up on the Trigger dialog: highlight the setup in the
Trigger List and touch the Update Selected button.
Delete a trigger: highlight the setup in the Trigger List and touch the Delete Selected button.
All trigger setups can be deleted in one step by touching the Delete All button.

3. Optionally:
l

Enter a Dwell Time the time instrument should wait before loading the next trigger.
Check the Stop On Trigger checkbox. You can use this to isolate events as the triggers find
them.
Note: If you have Persistence enabled, all trigger events are recorded on the display.

Saving TriggerScan Setups
You can preserve the Trigger List by saving it to a setup file. The current Trigger List is not preserved after
exiting the application unless you manually save it.
1. On the TriggerScan dialog, touch Setup File Name and enter a file name, or touch the Browse
button and select a location and file name.
2. Touch the Save Setup... button.
To reload a saved Trigger List, touch the Browse button, locating the file, then touch Load Setup....

Running TriggerScan
When the Trigger List is set, touch the Start Scan button on the Trigger Scan dialog. The instrument
automatically cycles through all the triggers in the list.
To run only a single trigger, select it from the Trigger List and touch Load Selected. The trigger settings
are copied to the Trigger dialog and will be used when you start acquisition.

Display

Display
Display settings affect the number and style of grids that appear on screen and some of the visual
characteristics of traces, such as persistence.

Multi-Grid Display
WaveRunner 8000Zi series oscilloscopes feature multi-grid display, where each separate grid represents
the full number of 256 vertical levels.
Auto Grid Mode is enabled by default. This feature adds a grid each time a new trace is opened, up to 16
grids, until no more grids are available. There are display options to show all traces on a Single Grid, or to
manually divide the display into different numbers and orientations of grids. The Grid Mode icon shows
what the result of the selection will be.

Multi-grid display.

WaveRunner 8000 Oscilloscopes Instruction Manual

Q-Scape Multi-Tabbed Display
Available with the Q-Scape option, the Q-Scape Display Modes divide the screen into multi-tab displays,
each of which can be configured with a different multi-grid display mode. Many of the same functions you
can perform in Normal mode, such as moving traces by drag-and-drop, you can also perform in Q-Scape
modes.
The Display Mode setting determines whether the touch screen has a single display area ("Normal" mode)
or tabs each representing a separate display (the various "Q-Scape" modes). The Grid Mode setting
determines how grids are configured within the display area and what kind of traces they show (for
example, XY or VT). Normal Display Mode (a single display) is the default.

Multi-tab display with different grid styles.

Display

Display Set Up
To access the Display dialog, choose Display > Display Setup.

Display Mode (Q-Scape only)
The Display mode determines the number and layout of display tabs. Choose Normal (default), a single
display with no tabs, or one of the three Q-Scape display modes:
l

Q-Scape Single, a single set of four tabs stacked so that only one at a time is visible. Each tab can
have any style of grid mode, same or different.

Q-Scape Dual, two sets of four stacked tabs. Equivalent tabs in each set share the same grid mode,
but can display different traces. You can simultaneously view one tab from each set, but they must
be different numbered tabs (e.g., Tab 1 from set one and Tab 3 from set two).

WaveRunner 8000 Oscilloscopes Instruction Manual
l

Q-Scape Mosaic, a single set of four tabs arranged so that all are viewed simultaneously.

In Q-Scape modes, channel, math, memory, and zoom descriptors appear in the tab where the trace is
open, while Timebase and Trigger descriptors remain outside the tabs, since they are not associated with
any one trace.
Note: If you switch from Normal mode into any Q-Scape mode, all traces will move to Tab 1, from
which you can drag-and-drop to redistribute them to other grids. In Q-Scape Single mode, you will
not be able to drag-and-drop traces across tabs, only to other Tab1 grids.
To rename Q-Scape tabs after they open:
1. Touch-and-hold (right-click) on the Tab <#> until Rename pops up.
2. Touch Rename.
3. Enter the New Alias, then touch OK.

Extended Display
Note: The "Extend Grids..." option only appears when a second monitor is connected. Minimize the
oscilloscope window and use the standard Windows Display controls to make the instrument the
primary display. It should be extended, not duplicated.
To take advantage of an extended display in Q-Scape mode:
1. On the Display dialog, select Extend Grids Onto 2nd Monitor. The Select Grid pop-up opens.
2. Switch to the Extended Display submenu and choose a Grid style. Tab 1 and the external monitor
will share the same grid style.
Tip: Drag-and-drop descriptor boxes to place traces on the desired grids.To take full advantage of
Q-Scape on the larger display, choose File > Windowed on the instrument, then grab the window
title bar and drag it to the external monitor screen. Drag the Extended Display window to the
instrument screen.

Grid Intensity
To dim or brighten the background grid lines, touch Grid Intensity and enter a value from 0 to 100.
Grid on top superimposes the grid over the waveform.
Note: Some waveforms may be hidden from view with the grid on top.
Axis labels display the values represented by each division of the grid, based on your vertical scale and
timebase. Turned on by default, they may appear as absolute values or delta from center (0). Deselect the
checkbox to remove them from the display.

WaveRunner 8000 Oscilloscopes Instruction Manual

Trace Intensity
Choose a line style for traces: solid Line or disconnected sample Points.
When more data is available than can actually be displayed, Trace Intensity helps to visualize significant
events by applying an algorithm that dims less frequently occurring samples. Touch Intensity and enter a
value from 0 to 100.

Intensity 40% (left) dims samples that occur ≤ 40% of the time to highlight the more frequent samples,
vs. intensity 100% (right) which shows all samples the same.

XY Plots
XY plots display the phase shift between otherwise identical signals. They can be used to display either
voltage or frequency on both axes, each axis now corresponding to a different signal input, rather than a
different parameter. The shape of the resulting pattern reveals information about phase difference and
frequency ratio.
Note: The inputs can be any combination of channels, math functions, or memories, but both
sources must have the same X-axis scale.
Choose an XY grid mode and select the sources for Input X and Input Y.

Sequence Display Mode
Use these settings to select the Display Mode used when sampling in Sequence mode.

Display

Persistence Display
The Persistence feature retains waveform traces on the display for a set amount of time before allowing
them to gradually "decay," similar to the analog-style display of old, phosphor screen oscilloscopes.
The display is generated by repeated sampling of events over time and the accumulation of the sampled
data into "persistence maps". Statistical integrity is preserved because the duration (decay) is proportional
to the persistence population for each amplitude or time combination in the data.
The different persistence modes show the most frequent signal path in three-dimensional intensities of
the same color (Analog), or in a graded spectrum of colors (Color).
The Ptrace math functions compute a vector trace based on a persistence map that can be used for
further analysis. The Phistogram math function can be used to statistically represent the frequency of
samples within a vertical and/or horizontal slice of a persistence map.
Access the Persistence dialog from the Display dialog or by choosing Display > Persistence Setup.

Apply Persistence
1. Check Persistence On.
2. To set up all traces together, touch All Locked. This constrains all input channels to the same
persistence settings.To set up traces individually, touch Per Trace.
3. Use the buttons to select a persistence mode:
Color Mode persistence works on the same principle as Analog
persistence, but instead uses the entire color spectrum to map signal
intensity: violet for minimum population, red for maximum population. In
this mode, all traces use all colors, which is helpful for comparing
amplitudes by seeking like colors among the traces.
In Analog Mode, as a persistence data map develops, different intensities
of the same color are assigned to the range between a minimum and a
maximum population. The maximum population automatically gets the
highest intensity, the minimum population gets the lowest intensity, and
intermediate populations get intensities in between these extremes. The
information in the lower populations (for example, down at the noise level) could be of greater
interest to you than the rest. The Analog persistence view highlights the distribution of data so that
you can examine it in detail.

WaveRunner 8000 Oscilloscopes Instruction Manual
3d Mode persistence creates a topographical view of your waveform from a selection of shadings,
textures, and hues. The advantage of the topographical view is that areas of highest and lowest
intensity are shown as peaks and valleys, in addition to color or brightness. The shape of the peaks
(pointed or flat) can reveal further information about the frequency of occurrences in your
waveform. You choose the Quality of the 3D display:
Solid quality can be either color or monochrome. Saturation is set at 50%,
with hotter colors indicating highest intensity.
In the monochrome view of solid, the lightest areas indicate highest
intensity, corresponding to the red areas in the color view.
In shaded (projected light) quality, the shape of the pulses is emphasized.
This quality is monochrome only.
In wire frame quality, lines of equal intensity are used to construct the
persistence map. This display can be either color or Monochrome.
In 3d mode, X Axis Rotation and Y Axis Roation can range 180° from -90° to +90°. In the examples
above, the X-axis is rotated 60° an the Y-axis 15°.
Tip: To quickly rotate the graph, grab a corner of the persistence map and drag it in the
desired direction.
4. Select the Saturation level as a percentage of the maximum population. All populations above the
saturation population are assigned the highest color intensity: that is, they are saturated. At the
same time, all populations below the saturation level are assigned the remaining intensities. Data
populations are dynamically updated as data from new acquisitions is accumulated. A saturation
level of 100% spreads the intensity variation across the entire distribution; at lower saturation levels
the intensity will saturate (become brighter) at the percentage value specified. Lowering this
percentage causes the pixels to be saturated at a lower population and makes visible those events
rarely seen at higher saturation levels.
5. In Persistence Time, enter the duration of time (in seconds) after which persistence data is erased
from the display.
6. Choose to superimpose the last waveform over the persistence display by selecting Show Last
Trace (not available in 3d mode).
7. To display persistence traces as a continuous line (instead of a series of sample points), select Dot
Joined.

Remove Persistence
To turn off persistence and return to the regular trace style, clear Persistence On or select an individual
trace's None (left-most) persistence mode button.

Math and Measure

Math and Measure
Teledyne LeCroy offers a rich set of standard, pre-programmed tools for the "quickest time to insight" into
the characteristics of acquired waveforms. Most instruments calculate measurements for all samples in
an acquisition, enabling you to rapidly and thoroughly calculate thousands or millions of parameter values
and apply a variety of mathematical functions to the input waveform trace.

Cursors
Cursors are markers (lines, cross-hairs, or arrows) that identify voltage and time values on the waveform.
Use cursors to make fast, accurate measurements of specific points in the waveform. There are five,
standard cursor types available.
Vertical (amplitude) cursor readouts appear the trace descriptor box; Horizontal (time) cursor readouts
appear below the Timbebase descriptor box.
Cursors can be placed on math functions whose X-axis has a dimension other than time, such as an FFT.
When there is at least one non-time-domain math trace open, the Standard Cursors dialog contains an XAxis control where you can choose the units measured by the horizontal cursors. The options will be
appropriate to the types of function traces open; for example, if there is an FFT trace, there is an option for
Hz. The cursor lines are placed on the traces that normally display X-axis values in the selected units.

Horizontal Relative cursors.

WaveRunner 8000 Oscilloscopes Instruction Manual

Cursor Types
Horizontal (Time) cursors intersect points on the horizontal axis.
l

Horizontal Abs displays a single, dashed, vertical line. The readout shows the absolute value at the
cursor location.
Horizontal Rel displays two, dashed, vertical lines. The readout may be in absolute values or a delta
of the two points, depending on the Show option selected.

Vertical (Amplitude) cursors intersect points on the vertical axis.
l

Vertical Abs displays a dashed, horizontal line. The readout shows the absolute value at the cursor
location.
Vertical Rel displays two dashed, horizontal lines. As with Horizontal Relative cursors, the readout
may show absolute values or a delta.

The Both Rel(ative) option places both Vertical and Horizontal Relative cursors together.

Apply and Position Cursors
Apply Cursors
To turn on cursors, either:
l

From the menu bar, choose Cursors and select the desired cursor type from the drop-down list.
On the front panel, press the Cursor Type button repeatedly to cycle through all the cursor types.
Stop when the desired type is displayed.
Note: There must be a waveform on the grid for cursors to execute, although acquisition may be in
process or stopped when you turn them on.

To turn off cursors, choose Cursors > Off, or continue cycling the button until they disappear.

Position Cursors
The easiest way to reposition a cursor is to drag-and-drop the cursor marker to a new position. Indicators
outside the grid show to which trace the cursor belongs when you have multiple traces on one grid.
Alternatively, turn the front panel Cursors knob. If both vertical and horizontal cursors are turned on, push
the knob until the correct line is selected, then turn to move it. When there are multiple traces each with its
own cursors on the same grid, bring the desired trace to the foreground by touching the trace or its
descriptor box. The Cursors knob will only operate on the foreground trace.
If Horizontal cursors are applied to a source trace but do not appear on its dependent traces (e.g., a zoom)
because of differences in scale, drag-and-drop the cursor readout from below the Timebase descriptor
box onto the target trace or its descriptor box. This applies the same cursors at the 5 (single cursor) or 2.5
and 7.5 (relative cursors) division mark of the target trace and adjusts source cursors accordingly.

Math and Measure
Note: Horizontal Relative cursors are initially placed one on the negative side of the X-Axis (marked
by ⇓) and one on the positive side (marked by ⇑). If you move the negative cursor to the right of
the positive cursor, or vice versa, the delta is shown in negative increments.

Standard Cursors Dialog
These controls can be used instead of the front panel controls to set cursors or to refine the cursor
position. Access the dialog by choosing Cursors > Cursors Setup from the menu bar.

Cursors On displays or hide cursor lines. When first checked, the last selected cursor type is displayed.
Cursor Type buttons select the type of cursor displayed on the grid.
The Show controls determine which values are shown in the readout, particularly when using relative
cursors:
l

Absolute shows specific voltages for the two cursor locations.

Delta shows the difference between the specific voltages at the cursor locations.

Abs+Delta shows both the absolute and delta readouts.

Slope (Horizontal Relative only) shows the slope of the waveform between the cursor locations.

The Position controls at the right-side of the Standard Cursors dialog display the current cursor location
and can be used to set a new location. The options available depend on the Cursor Type and Show
settings.
l

X 1 (negative) and X 2 (positive) sets time from the zero point.
Y 1 (negative) and Y 2 (positive) sets number of divisions from the zero level. May be a fraction of a
division.
Track locks cursor lines so they move together, maintaining their same relative distance from each
other.

XY Cursors Dialog
If your Grid Mode selection includes an XY trace display, an XY Cursors dialog appears behind the
Standard Cursors dialog. Use it to exactly position and track the cursors on the XY trace, the same as you
use the settings on the Standard Cursors dialog for VT traces. The functionality is the same.

WaveRunner 8000 Oscilloscopes Instruction Manual

Measure
Measurement parameters are tools that give you access to a wide range of waveform properties. Use
them to analyze many attributes of your waveform such as rise-time, rms voltage, and peak-to-peak
voltage. Measurements can also be graphed as a histrogram, track, or trend for statistical analysis.
The instrument offers a quick selection of standard horizontal and vertical measurements, or you can
create a custom set of parameters (My Measure) drawn from all available measurements.

Measure Table
Measurement readouts appear in a table below the grid. The value row shows the measurements taken
for each parameter on the last cycle of the last acquisition. Other rows show optional statistics.

Measurement Status Indicators
Symbols in the status row of the Measure table indicate the following:
Symbol Description
Problem with the signal or the setup. Touch cell to see explanation in message bar.
Valid value returned.
Unable to determine top and base; however, measurement may still be valid.
Underflow condition.
Overflow condition.
Simultaneous underflow and overflow condition.

Navigating with the Table
Close setup dialogs when the Measure table is displayed to maximize the touch screen area available for
viewing waveforms. The table itself can be used to quickly access setup dialogs. To open the Parameter
Setup (Px) dialog, touch the Px cell of the table. Touch the far left Measure column to open the Measure
dialog and modify the table contents. The table is static when using the standard measurements, as these
cannot be changed.

Quick Table Setup
Any parameter can be copied by dragging the cell onto the target cell of the table. Then, drag the desired
measurement source descriptor box onto the new parameter. Touch the cell to make any other
modifications on the Px dialog.

Math and Measure

Measure Dialog
The Measure Dialog gives quick access to measurement features. Besides turning on/off parameters, use
the Measure dialog to display Statistics, Histicons, or Help Markers for standard and user-defined
parameter sets. You can also Gate the standard parameter sets to limit the horizontal scope of the
measurement. All standard parameters will share the same gate. (Use the Px dialogs to gate user-defined
parameters.)

Select Measurements
1. To open the Measure dialog, touch the Add New box and select Measurement, or choose Measure
> Measure Setup from the menu bar.
2. Check Show Table to display the measurement readout on screen.
3. Check the selection box for each measurement you wish to display. Touch the Px button to define
a new measurement.

Standard Parameter Sets
Pre-configured standard parameter sets are available for quick display. Choose either:
l

Std Vertical: mean, sdev, max., min., ampl, pkpk, top, base.

Std Horizontal: freq, period, width, rise, fall, delay, duty, num points.

To define your own parameter set, choose My Measure. Open the Px dialogs to define new parameters.
Once parameters are configured, select the On checkbox next to each parameter to turn on the
measurement.
To quickly begin a new parameter set based on the standard vertical or horizontal sets, touch Quick
Setups and choose the set to copy. Refine the settings on the Px dialogs.Touch Clear All to remove all
measurement definitions.
Caution: Definitions cannot be restored after clearing, you must repeat measurement set up.

Statistics
Checking Statistics On adds the measures mean, min., max., sdev, and num(ber of measurements
computed) to the table.
For any parameter that computes on an entire waveform (like amplitude, mean, minimum, maximum,
etc.) the num statistic represents the number of sweeps.

WaveRunner 8000 Oscilloscopes Instruction Manual
For any parameter that computes on every event, the num statistic represents the number of events per
acquired waveform. If x waveforms were acquired, num is x times the number of cycles per waveform.
To reset the statistics counter, touch Clear Sweeps on the display or front panel.

Histicons
Histicons are miniature histograms of measurement parameters that appear on the measurement table.
These thumbnail histograms let you see at a glance the statistical distribution of each parameter. Select
the Histicons checkbox to turn on histicons.
Tip: You can quickly display a full histogram by touching the histicon you want to enlarge.

Help Markers
Help Markers clarify measurements by displaying lines, labels and hysteresis bands to mark the points
being measured on the trace. For "@Level" parameters, markers make it easier to see where your
waveform intersects the chosen level.
You can choose to use Simple markers, which are only the lines, or Detailed markers, which include the
measurement point labels.
You also have the option, by means of the Always On checkbox, to leave the markers displayed over
traces after you have closed the Measure dialogs or readout table. If you change the set of parameters
displayed, the markers will change, as well.
Note: Unlike regular cursors, which are white and can be moved, help markers are blue and only
augment the display; they cannot be moved, and they do not reset the measurement points. Some
optional analysis software packages include markers designed specially for that domain of
reference, which are documented in the option manual.

Detailed Help Markers on standard horizontal parameters.

Gate measurements (limit the horizontal scope of the measurement)

Qualify measurements (accept only measurements that meet additional conditions)

WaveRunner 8000 Oscilloscopes Instruction Manual

Gating Measurements
By using gates, you can narrow the span of the waveform on which to perform tests and measurements,
allowing you to focus on the area of greatest interest. For example, if you "gate" five rising edges of the
waveform, rise time calculations are performed only on the five pulses bounded by the gate posts.
The default starting positions of the gate posts are 0 div and 10 div, which coincide with the left and right
ends of the grid. Therefore, the gate initially encloses the entire waveform.
The quickest way to set a gate is to drag the gate posts from the far left and right of the grid to the desired
positions. You can refine this setting down to hundredths of a division by using the Gate Start and Stop
fields on the Gate subdialog.
Touch the Default button to return gates to the width of the trace.

Qualified Measurements
Some measurements can be constrained to a vertically or horizontally limited range of samples, or to
samples "gated" by the state of a second waveform. Both constraints can operate together. This
capability enables you to exclude unwanted characteristics from your measurements. It is much more
restrictive than a measure gate, which is used only to narrow the span of analysis along the horizontal axis.
Note: Since this feature operates on only a subset of the data, possible alerts or status indicators
concerning the measurement (such as "Data range too low") are not displayed.
If the measurement supports this feature, you will see the Accept subdialog next to the Px dialog for you to
define your constraints.

Math and Measure
Note: The correct units for the measurement (V, s, Hz, dB, etc.) are automatically
displayed. If you select a simple ratio parameter that yields a dimensionless number (such
as power factor) , units are omitted.

Waveform Gated Parameters
1. From the menu bar, choose Measure > Measure Setup, then touch the Px tab to open the
parameter setup dialog.
2. On the Accept subdialog, select Values Based on Waveform State.
3. Touch When Wform and select the gating waveform. It can be any waveform active at the same
time as the measurement source waveform.
4. Touch State Is and select High or Low from the pop-up menu. Measurements will only be taken
when the gating waveform is in the selected state.
5. Touch Level Type and select Absolute (voltage) or Percent (of amplitude) from the pop-up menu.
6. Enter the crossing Level value at which you want measurements to begin.
You can also touch the Find Level button to automatically set the level at 50% of the gating

Using Custom Scripts
On instruments installed with the Advanced Customization option (XDEV), custom scripts may be used to
define a measure parameter, math function, or math on parameters. Several scripting "languages" are
supported besides VBScript ( the instrument's "native tongue"), depending on the application. You can find
these options in the Custom submenu of the Measure/Math Selector. Scripts may be imported or written
in the instrument's Script Editor window and saved for future use. See Using P Script for a description of
the process.

Math on Parameters
In addition to measuring waveforms, you can set up a parameter that performs mathematical operations
on other parameters. Math on parameters differs from math functions in that the input and the output are
still numerical values that display in the measurement readout table. Math functions, on the other hand,
input and output waveform traces that appear on the grid.
The setup for math on parameters is much like that for other parameters. Some parameters can be
qualified on the Accept subdialog using value ranges or gating waveforms, as can regular waveform
measurements. If you have the Advanced Customization (XDEV) option, there is functionality for applying
custom scripts to calculate the results.

Exclusions
l

Multiplication and division of parameters that return logarithmic values

Source parameters that are the result of other parameter math operations

Setting Up Math on Parameters
1. From the menu bar, choose Measure > Measure Setup....
2. Choose Measure Mode My Measure and open a parameter setup (Px) dialog.
3. Touch the Math on Parameters button.
4. Touch Math Operator and choose an operation from the Select Measurement menu.
5. Touch the Source fields and select the parameters that are the inputs to the measurement.
6. Check On to enable the new output parameter and add it to the measurement readout.

Using P Script (Custom Math on Parameters)
On instruments installed with the Advanced Customization option (XDEV), you can write your own
VBScript or JavaScript to apply a mathematical operation to one or two input parameters. Choose the
Math Operator P Script. Scripting can be done directly on the instrument in the Script Editor window, or
you can import an existing script.
Note: Param Script is a VBScript or JavaScript that performs a measurement on one or two
waveforms to output a parameter. P Script, which is Math on Parameters, is a VBScript or
JavaScript that inputs one or two parameter values and performs a math operation on them to
output another parameter.

Using Web Editor
Whereas with Math on Parameters you can apply a single math operation to a measurement parameter,
the Web Editor enables you to create processes that potentially chain many operations and inputs,
including custom math and measurements (with the XDEV option). These processes are integral to the
operation of the instrument; there is no need to export data to other programs.
Processes are "programmed" in the X-Stream application simply by dragging and dropping a series of
blocks representing different math functions or measurements and connecting them to form a flow
chart—a "processing web." The terminal parameters and functions represent the final output of this
process.

Create Processing Web
1. From the menu bar, choose Measure > Measure Setup.
2. On the Measure dialog, choose Measure Mode My Measure.
3. Open the Px dialog and select Advanced Web Edit.

4. Touch the Show Processing Web button. You will see a "peg board" display with potential input
sources aligned along the left, and a terminal marked with the parameter number to the far right.

Math and Measure
5. On the Source Filter subdialog, deselect any types (e.g., zooms) that you do not want to use in the
process. This simplifes the display and reduces the need to scroll.
6. On the Wed Editor dialog, choose the type of process to add to the flow. You can Add Math, Add
Measure, or Add Param Math (Math on Parameters).
7. From the pop-up, choose the operation or measurement that will occur at that node. A new block
appears on the display. Drag the block to a location in the flow.
Tip: Touch the location to place a green plus sign before adding the node. Then, the new
block will be created at this spot. Otherwise, blocks may cover one another until moved.
8. The process block will have a input "pin" on the left. If a waveform is required, the pin is blue; if a
number is required, the pin is purple. Touch and drag a matching colored pin from the sources on
the left of the screen to the block. Choose as many sources as there are input pins on the block.
Tip: You may need to use the scrollbar to see all the available sources. For convenience,
the Math and Measure dialogs behind the Web Editor dialog summarize what is currently
configured for those sources.
When you drop the pin, a line is drawn from the source to the process. If a source is incompatible
with a process, you will not be able to pin it.

9. If the process requires additional configuration, a subdialog appears next to the Web Editor dialog.
Use it to enter the values to apply to that processing node.

WaveRunner 8000 Oscilloscopes Instruction Manual
10. Continue to add processes as needed, pinning the output of each block to the input of the next
block in the flow. The final process should be the same type as the terminal (in this example, a
measurement).
Note: The flow does not need to be strictly sequential, as many processes can accept
multiple inputs that may or may not have undergone other processes. The only
requirement is that the outputs are pinned to acceptable inputs. The color of the
input/output arrows indicates which connections are compatible.
11. Drag the output pin from the final process block to the input pin on the terminal.

Preview Outputs
You can add preview "windows" to see the output of a process at any stage in the flow. These previews
apply only to the Web Editor.
Select the output pin of the processing block you wish to preview. It will turn bright green. Then, on the
Web Editor dialog choose Add Preview.

Delete Process/Connection
To delete any process from the web, select the block then touch Delete. All the connections to/from it are
automatically deleted.
To remove a connection between process blocks, touch the line. A scissor icon appears above it. Confirm
whether or not to "cut" the connection.

Add Other Terminals to Processing Web
Other measurements or math functions can share the same processing web. For example, you may wish
to create a math function of the waveform that would result from a sub-processing node, while the final
output of the full process is a measurement parameter.
To add a terminal:
1. Open the Math or Measure dialog behind the Web Editor dialog.
2. Touch the Web Edit icon following the location (Px or Fx). The summary changes to Web Edit, and a
new terminal block appears on the Web Editor peg board.
3. Connect the output pin of the desired process to the input pin of the terminal. You can select
outputs that are already pinned to other blocks.

Math and Measure

Graphing Measurements
Measurements can be viewed in graphical formats to facilitate your analysis:
l

Histograms display the distribution of measured values for a given parameter as a bar chart.
Tracks provide a time-correlated view of a measurement parameter compared to other acquired
channels or calculated math traces. A common usage for track is to observe the modulation of a
signal, such as amplitude, frequency, or pulse width modulation.
Trends provide a view of a measurement parameter over an extended period of time and over
multiple acquisitions.

Action buttons at the bottom of the the Parameter (Px) dialogs let you quickly draw these plots for the
respective measurement.

Although these graphs plot measurement values, they are generated on the display as math functions (Fx)
and can be set up through either the Measure or Math dialogs.

Histogramming
Histograms graphically divide data points into intervals, or bins. These bins are plotted on a bar chart such
that the bar height relates to the number of data points within each bin.
Histograms are usually created to visualize the distribution of waveform parameter
values over one or more acquisitions. The Phistogram function creates a histogram of
values falling within a vertical or horizontal "slice" of a persistence map. Whatever the
source, histograms are always created as a math function. The number of sweeps (k#)
used to calculate the histogram is shown on the histogram function descriptor box.
Because the shape of histogram distributions is particularly interesting, additional histogram
measurements (found in the Statistics sub-menu of the Measure Selector) are available for analyzing
these distributions. They are generally centered on one of several peak value bins.
Thumbnail versions of parameter histograms are called Histicons. They are available as a checkbox option
on the Measure dialog. Histicons appear on the Measure table, rather than as a new math trace.

WaveRunner 8000 Oscilloscopes Instruction Manual
Plot Histogram
Conventional histograms are statistical tools that graph the occurrence of measured events in waveform
parameters such as amplitude, frequency, or pulse width. The histogram bar charts are divided into
intervals, or bins, where each bin contains a class of similar parameter values.
For a histogram of...

Use...

Different interval widths present in a long data stream

Histogram of Horizontal Parameter Period@level

Cumulative jitter on a long record of a clock signal

Histogram of Jitter Parameter TIE@level

Cycle-to-cycle jitter

Histogram of Horizontal Parameter Dperiod@level

To plot a histogram of a measurement:
1. Open the parameter setup (Px) dialog for the measurement you wish to histogram. A quick way to
do this is to touch the Measure table cell.
2. Touch the Histogram action button at the bottom of the Px dialog and choose the function (Fx) in
which to draw the histogram.
3. Touch the new hist descriptor box to display the Fx dialog, then open the Histogram subdialog.

4. Enter the maximum #Values in one bin of the histogram. This determines the number of samples
that are represented by the bar at full height.
5. Touch #Bins and enter the number of bins that comprise the histogram. This determines how
many bars appear in the histogram.
6. To let the software determine the range of values represented by each bin/bar, check Enable Auto
Find, then touch the Find Center and Width button. To set your own range, enter Center and Width
values.
7. Choose a Vertical Scale method:
l

Linear allows the histogram to build vertically as data accumulates. When the histogram
reaches the top of the display, it rescales the vertical axis to keep it on screen
LinConstMax keeps the histogram at near full scale and rescales the vertical axis as data is
accumulated.

Math and Measure
Optimizing Histograms
Histograms are dynamically computed using the last N events in the parameter buffer (# Values), up to 2
billion. If the number of bins or values is modified, the histogram is redrawn using the last N events
required. If the source of the histogrammed parameter is a memory, storing new data to memory
effectively acts as an acquisition trigger/sweep and updates the parameter buffer and the histogram.
When the ideal range required to form a good distribution is not apparent, the instrument's range finding
function can be used to calculate an optimal range and redraw the histogram using it. The instrument
gives a running count of where values fall relative to the range, and if any fall above or below it, the range
finder can recalculate the histogram using those values while still in the buffer.
Determining peak value bins, or histogram peaks, is very useful because they indicate dominant values of
a signal. However, signal noise and the use of a high number of bins relative to the number of parameter
values acquired can yield a spiky histogram, making meaningful peaks hard to distinguish. An optimal bin
number is one where the change in bin value is insignificant, and the histogram distribution does not have
a jagged appearance. The instrument analyzes histogram data to identify peaks from background noise
and histogram definition artifacts such as small gaps, which are due to very narrow bins.
Histogram bins represent a sub-range of waveform parameter values, or events. The events represented
by a bin may have a value anywhere within its sub-range. However, measurements of the histogram itself
assume that all events in a bin have a single value. The instrument uses the center value of each bin’s subrange in all its histogram measurements. The greater the number of bins used to subdivide a histogram’s
range, the less the potential deviation between actual event values and those values assumed in
histogram measurements. Nevertheless, using more bins may require a greater number of waveform
parameter measurements (from a greater number of sweeps) to populate the bins sufficiently for the
identification of a characteristic histogram distribution.
As with all measurements, the events used to calculate histograms correspond to the portion of the
waveform visible on the display, or bounded by the measure gates (the default gates are at the 0 and 10
div positions, enclosing the entire grid, or one full sweep).
In Sequence sampling mode, an acquisition for each segment occurs prior to parameter calculations, and
a sweep is equivalent to acquisitions for all segments. If a single segment is selected for viewing, the
histogram will be recalculated for only the displayed/gated events in that segment.
For non-segmented waveforms, an acquisition is identical to a sweep. Measurements that yield only one
value per acquisition (Amplitude, Area, Base, Cycles, Delay, Delta Delay, Dtime@level, Duration, First, Last,
Maximum, Mean, Median, Minimum, Nb Phase, Nb Power, Overshoot+, Overshoot-, Peak-Peak, Phase,
Points, RMS, Std Dev., etc.) may not produce the best histograms unless you allow sweeps to accumulate
over many acquisitions.

Plot Track
A Track is a plot composed of parameter measurements that is time synchronous with the source
waveform. The vertical units are those of the source parameter and the horizontal units are seconds. In
order to maintain time synchronism, the parameter values are posted at the sampling rate.
In general, Track is the tool to use if you want to capture a continuous stream of data spaced closely
together. Track values are redundant in that the same value is repeated every sample period until the
measurement changes.
1. Open the parameter setup (Px) dialog for the measurement you wish to track. A quick way to do
this is to touch the Measure table cell.
2. Touch the Track toolbar button at the bottom of the Px dialog and choose the function (F1-Fx) in
which to draw the plot. The track opens in a new grid along with its function descriptor box.
3. Touch the new Track descriptor box to display the Fx dialog, then open the Track subdialog.

Math and Measure
4. On the Track subdialog, use Find Scale to automatically find suitable values, or uncheck Auto Find
Scale and enter a custom Center and Height/div.
5. Choose a line Connect function of either Interpolate or Extend.
Plot Trend
A Trend is a plot composed of a series of parameter measurements in the order the measurements were
taken. The vertical units are those of the source parameter, the horizontal unit is measurement number.
The Trend contains a single value for each measurement. Think of Trend as a strip chart recorder for your
instrument.
Trends are especially useful for visualizing the history of a parameter over an extended period of time or
over multiple acquisitions. Trend can be used if your data is spaced widely apart and longer than the deadtime between acquisitions.
1. Open the parameter setup (Px) dialog for the measurement you wish to histogram. A quick way to
do this is to touch the Measure table cell.
2. Touch the Trend button at the bottom of the Px dialog and choose the function (Fx) in which to
draw the plot. The Trend opens in a new grid along with its function descriptor box.
3. Touch the new Trend descriptor box to display the Fx dialog, then open the Trend subdialog.

4. Choose a computation Mode of All (plots multiple points per acquisition) or Average (plots one point
per acquisition). Enter the number of measured Values to Trend.
5. To rescale the Trend, use Find Scale to automatically find suitable values, or uncheck Auto Find
Scale and enter custom Center and Height/div values.

WaveRunner 8000 Oscilloscopes Instruction Manual

Calculating Measurements
The instrument uses the following methods to calculate measurements.

Determining Top and Base Lines
Proper determination of the top and base reference lines is fundamental for ensuring correct parameter
calculations. The analysis begins by computing a histogram of the waveform data over the time interval
spanned by the left and right measurement gates. For example, the histogram of a waveform transitioning
in two states will contain two peaks (see figure). The analysis will attempt to identify the two clusters that
contain the largest data density. Then the most probable state (centroids) associated with these two
clusters will be computed to determine the top and base reference levels: the top line corresponds to the
top and the base line to the bottom centroid.

Determining Rise and Fall Times
Once top and base are estimated, rise and fall times are calculated. The appropriate threshold levels are
automatically determined by the instrument, using the amplitude (ampl) parameter.
Threshold levels for rise or fall time can also be selected using absolute or relative settings ( if @level
measurements are included with your model). When absolute settings are chosen, the rise or fall time is
measured as the time interval separating the two crossing points on a rising or falling edge. When relative
settings are chosen, the vertical interval spanned between the base and top lines is subdivided into a
percentile scale (base = 0 %, top = 100 %) to determine the vertical position of the crossing points. The
time interval separating the points on the rising or falling edges is then estimated to yield the rise or fall
time. These results are averaged over the number of transition edges that occur within the observation
window.

Math and Measure
Rising Edge Duration

Falling Edge Duration

Where Mr is the number of rising edges found, Mf the number of falling edges found,
rising edge i crosses the x% level, and

the time when

the time when falling edge i crosses the x% level.

Determining Time Parameters
Time parameter measurements such as width, period and delay are carried out with respect to the mesial
reference level, located halfway (50%) between the top and base reference lines or with respect to the
specified level for @level parameters.
Time-parameter estimation depends on the number of cycles included within the observation window. If
the number of cycles is not an integer, parameter measurements such as rms or mean will be biased.
However, only the last value is actually displayed, the mean being available when statistics are enabled. To
avoid these bias effects, cyclic parameters can be chosen, including crms and cmean, that restrict the
calculation to an integer number of cycles.

Determining Differential Time Measurements
The instrument enables accurate differential time measurements between two traces: for example,
propagation, setup and hold delays.
Parameters such as Skew require the transition polarity of the clock and data signals to be specified. A
hysteresis range may be specified to ignore any spurious transition that does not exceed the boundaries of
the hysteresis interval. In the figure below, Skew measures the time interval separating the falling edge of
Source1 from the rising edge of Source2.

Math and Measure

Math
Math traces (Fx) display the result of applying a mathematical operation to a source trace. The output of a
math function is always another trace, whereas the output of a measurement parameter is a tabular
readout of the measurement.
Math can be applied to any channel (Cx), zoom (Zx), or memory (Mx) trace. It can even be applied to
another math trace, allowing you to chain operations (for example, trace F1 can show the average of C1,
while trace F2 provides the integral of F1). Functions such as Trend can be applied to measurement
parameters (Px) to plot the history of the measurement.
In addition to the extensive math capabilities that are standard with every instrument, enhanced math
analysis tools customized for various industries and applications are offered through optional software
packages. To learn about math tools available in each optional package, see the product datasheets at
teledynelecroy.com.
If you have installed software options, the new capabilities are usually accessed through the Analysis
menu, rather than the Math menu, although special measure parameters and math functions will be
available when using Measure and Math dialogs.

Math Function Set Up
Use the Function dialog to set up math function traces. Math functions take as input one or more channel,
zoom, memory or math traces and output a new function trace (Fx). Any additional settings required for
the operator will appear on a subdialog at the right of the screen.
Single functions perform one operation on one or two input sources.
Dual functions chain two operations to arrive at a single result. This saves you the effort of having to chain
two separate math functions. As with single functions, the number of sources required will vary based on
the operation. You may need only one source for Operator1, but two for Operator2 (the result of the first
operation counts as one source).

Setting Up New Functions
1. From the menu bar choose Math > Math Setup, or press the front panel Math button.
2. Choose a location by touching one of the Fx tabs.
If you know which function location you'll be using, you can select Fx Setup right from the Math
menu.

3. Choose a single f(x) or dual g(f(x) operator function.

109

WaveRunner 8000 Oscilloscopes Instruction Manual
You can also choose Web Edit, in which case this function is added as a terminal to the processing
web. See the instructions for Using Wed Edit to set up the function.
4. In Operator1, choose the math operation to perform.
Note: On instruments with the Advanced Customization (XDEV) option, the Operator can be
a custom script written in one of several scripting "languages." Choose from the Custom
submenu and import or write the script in the Script Editor. See Using PScript for a
description of the process.
5. The choice of operator drives the number of Source fields you will see displayed. Make a selection
in each field, or drag the source channel descriptor box to the field.
A Summary of the function you are building appears on the dialog. Refer to this to be sure your
sources are in the proper order to yield the function you want (e.g., C1-C2 vs. C2-C1).
6. If the operator you've selected has any other configurable settings, you'll see a subdialog of the
same name as the operator. Touch the tab to open the dialog and make any further settings. These
are explained on the dialog.
7. If you're creating a dual function, repeat the procedure for the second operator.

Graphing
The Graph button on the Function (Fx) dialogs allows you to simultaneously apply a measurement
parameter to the function trace and plot the results using histogram, track, or trend. See Histogramming
and Track and Trend.
Tip: The plots are the same as those created using the toolbar on the Parameter (Px) dialog.
As with other math functions, configurable settings will appear on subdialogs after the plot is selected.

Adjusting Memory or Math Traces
Unlike channel traces, the scale of memory (Mx) or math function (Fx) traces can be adjusted directly
without having to create a separate zoom trace. The same set of zoom factor controls used for zoom
traces appear on the Zoom subdialog, but in this context they only rescale the active math or memory
trace rather than create a new zoom. This applies to any trace that is created as a math function (Fx)
trace, including traces generated through analysis options and graphs.
You can, if you wish, create a separate zoom trace from a memory or function trace the same as you
would normally create a zoom (draw a selection box, Add New Zoom, etc.). In this case, you choose one of
the zoom locations (Zx) in which to draw the trace, but the source trace remains at the original scale.

110

Math and Measure

Math Dialog
Once a math function has been created and saved on the Function (Fx) dialog, use the main Math dialog
to quickly enable/disable it. You can also use this dialog to quickly turn on/off zoom traces.

To open the Math dialogs, touch the front panel Math button, or from the menu bar choose Math > Math
Setup. Select the On checkbox next to each function you wish to display.
To modify a function, touch the Fx button.
To erase all functions from their locations, touch Reset All.
To restart the counter on cumulative functions (like Average), touch Clear Sweeps.

Average Function
Setting Up Averaging
To apply Continuous or Summed Averaging as a Math function:
1. Follow the usual steps to set up a math fuction, selecting Average from the Basic Math submenu.
2. On the Average subdialog, choose Summed or Continuous.
3. Touch Sweeps and provide a value. The valid range is 1 to 1,000,000 sweeps.
Tip: To quickly set up Continuous Averaging (only), access the channel setup dialog (Cx) and enter
the number of sweeps to average in Averaging. The valid range is 1 to 1,000,000 sweeps.

Summed Averaging
Summed Averaging is the repeated addition, with equal weight, of successive source waveform records. If
a stable trigger is available, the resulting average has a random noise component lower than that of a
single-shot record. Whenever the maximum number of sweeps is reached, the averaging process stops. In
Summed averaging, you specify the number of acquisitions to be averaged. The averaged data is updated
at regular intervals.
An even larger number of records can be accumulated simply by changing the number in the dialog.
However, the other parameters must be left unchanged or a new averaging calculation will be started. You
can pause the averaging by changing the trigger mode from NORMAL/AUTO to STOP. The instrument
resumes averaging when you change the trigger mode back to NORMAL/AUTO.
You can reset the accumulated average by pushing the CLEAR SWEEPS button or by changing an
acquisition parameter such as input gain, offset, coupling, trigger condition, timebase, or bandwidth limit.
The number of current averaged waveforms of the function, or its zoom, is shown in the acquisition status
dialog. When summed averaging is performed, the display is updated at a reduced rate to increase the
averaging speed (points and events per second).

Continuous Averaging
Continuous Averaging, the default setting, is the repeated addition, with unequal weight, of successive
source waveforms. It is particularly useful for reducing noise on signals that drift very slowly in time or
amplitude. The most recently acquired waveform has more weight than all the previously acquired ones:
the continuous average is dominated by the statistical fluctuations of the most recently acquired
waveform. The weight of ‘old' waveforms in the continuous average tends to zero (following an
exponential rule) at a rate that decreases as the weight increases.
You determine the importance of new data vs. old data by assigning a weighting factor. Continuous
averaging allows you to make adjustments to a system under test and to see the results immediately. The
formula for both summed and continuous averaging is:
new average = (new data + weight * old average)/(weight + 1)

112

Math and Measure
However, by setting a Sweeps value, you establish a fixed weight that is assigned to the old average once
the number of sweeps is reached. For example, for a sweeps (weight) value of 4:
Sweep

New Average =

1 (no old average yet)

(new data +0 * old average)/(0 + 1) = new data only

(new data + 1*old average)/(1 + 1) = 1/2 new data +1/2 old average

(new data + 2 * old average)/(2 + 1) = 1/3 new data + 2/3 old average

(new data + 3 * old average)/(3 + 1) = 1/4 new data + 3/4 old average

(new data + 4 * old average)/(4 + 1) = 1/5 new data + 4/5 old average

In this way, for sweeps > 4 the importance of the old average begins to decrease exponentially.
Note: The number of sweeps used to compute the average is displayed at the bottom of the trace
descriptor box.

Copy Function
The Copy math function saves a copy of your present waveform in its unprocessed state to the first
available memory location. While processing may continue on the original waveform, the copy enables
faster throughput in some cases by preserving the original data. No calculations need to be undone on the
copy before additional math can be calculated. This benefit of faster throughput, however, comes at the
expense of memory usage.
Follow the ususal steps to set up a math function, selecting Copy from the Misc submenu.
On the Wform Copy subdialog, optionally Reset Count or Change BatchSize.

113

WaveRunner 8000 Oscilloscopes Instruction Manual

ERes Function
ERes (Enhanced Resolution) filtering increases vertical resolution, allowing you to distinguish closely
spaced voltage levels. The instrument's ERes function is similar to smoothing the signal with a simple,
moving-average filter. However, it is more efficient concerning bandwidth and pass-band filtering.
Use ERes:
l

On single-shot acquisitions, or where the data record is slowly repetitive (cases where you cannot use
averaging).

To reduce noise on noticeably noisy signals when you do not need to perform noise measurements.

When performing high-precision voltage measurements (e.g., zooming with high vertical gain).

Setting Up ERes
To apply ERes as a Math function:
1. Follow the usual steps to set up a math function, selecting Eres from the Filter submenu.
2. Touch the Trace On checkbox.
3. On the Eres subdialog, then touch bits and make a selection from the pop-up menu.
Tip: To quickly set up ERes as a pre-processing function, access the channel setup dialog (Cx) and
select a Noise Filter (ERes) bit size.

How the Instrument Enhances Resolution
The instrument's enhanced resolution feature improves vertical resolution by a fixed amount for each
filter. This real increase in resolution occurs whether or not the signal is noisy, or whether it is single-shot or
repetitive. The signal-to-noise ratio (SNR) improvement depends on the form of the noise in the original
signal. The enhanced resolution filtering decreases the bandwidth of the signal, filtering out some of the
noise.
The instrument's constant phase finite impulse response (FIR) filters provide fast computation, excellent
step response in 0.5 bit steps, and minimum bandwidth reduction for resolution improvements of between
0.5 and 3 bits. Each step corresponds to a bandwidth reduction factor of two, allowing easy control of the
bandwidth resolution trade-off.

With low-pass filters, the actual SNR increase obtained in any particular situation depends on the power
spectral density of the noise on the signal.
The improvement in SNR corresponds to the improvement in resolution if the noise in the signal is white
(evenly distributed across the frequency spectrum). If the noise power is biased towards high frequencies,
the SNR improvement will be better than the resolution improvement.
The opposite may be true if the noise is mostly at lower frequencies. SNR improvement due to the
removal of coherent noise signals—feed-through of clock signals, for example—is determined by the fall of
the dominant frequency components of the signal in the passband. This is easily ascertained using
spectral analysis. The filters have a precisely constant zero-phase response. This has two benefits. First,
the filters do not distort the relative position of different events in the waveform, even if the events'
frequency content is different. Second, because the waveforms are stored, the delay normally associated
with filtering (between the input and output waveforms) can be exactly compensated during the
computation of the filtered waveform.
The filters have been given exact unity gain at low frequency. ERes should therefore not cause overflow if
the source data is not overflowed. If part of the source trace were to overflow, filtering would be allowed,
but the results in the vicinity of the overflowed data—the filter impulse response length—would be
incorrect. This is because in some circumstances an overflow may be a spike of only one or two samples,
and the energy in this spike may not be enough to significantly affect the results. It would then be
undesirable to disallow the whole trace.
Note: While ERes improves the resolution of a trace, it cannot improve the accuracy or linearity of
the original quantization. The pass-band causes signal attenuation for signals near the cut-off
frequency. The highest frequencies passed may be slightly attenuated. Perform the filtering on
finite record lengths. Data is lost at the start and end of the waveform and the trace ends up
slightly shorter after filtering. The number of samples lost is exactly equal to the length of the
impulse response of the filter used: between 2 and 117 samples. Normally this loss (just 0.2 % of a
50,000 point trace) is not noticed. However, you might filter a record so short that no data is
output. In that case, however, the instrument would not allow you to use the ERes feature.

Fast Wave Port Function
Fast Wave Port is a function of Teledyne LeCroy X-Stream oscilloscopes that enables you to insert a
custom algorithm written in the C/C++ language into the oscilloscope's processing stream. It also
maximizes data throughput from the acquisition system to your custom algorithm for purposes of
debugging. Custom algorithms can be written right on the oscilloscope using the Script Editor.
This is possible because two Windows system processes may share a region of memory, enabling highspeed data transfer between the acquisition system and the custom algorithm, which runs in a separate
process from the oscilloscope application. A major benefit of Fast Wave Port is that your algorithm may be
implemented and, more importantly, debugged independently of the main application.
It is important to note that transferring the results of your algorithm back into the X-Stream processing
stream is optional. If performance is the primary goal, and further processing of the results within the XStream software is not required, this step may be skipped.
Fast Wave Port was designed for use with the C/C++ programming language. However, it is theoretically
possible for the processing to be implemented in any language supporting Windows named events
(Mutex) that can open a named memory-mapped file. No guarantee can be given, however, as to the
behavior of the function using anything but C/C++.
The size of the memory window is fixed at 80 MB, equating to 40 ms.
See the Fast Wave Port topic in the oscilloscope Help for an example C++ application.
To use Fast Wave Port, follow the usual steps to set up a math function, selecting Fast Wave Port as the
Operator, then make the appropriate settings on the Fast Wave Port subdialog.
The Port Name is critical, indicating the base name of the memory window and the global objects within
the Windows O/S. Only change the default value if using multiple Fast Wave Port functions in parallel.
Note: The base name must match the base name used in the client application.
The full names of the default global objects are as follows:

The Timeout control specifies the amount of time the DSO waits for the custom processing function to
complete. This prevents the DSO from waiting indefinitely for a custom processing function which may
never arrive. Be careful to set this control to a reasonable value, meaning a time longer by a reasonable
margin than the custom processing is ever expected to take.

116

Math and Measure

FFT Function
For a large class of signals, you can gain greater insight by looking at spectral representation rather than
time description. Signals encountered in the frequency response of amplifiers, oscillator phase noise and
those in mechanical vibration analysis, for example, are easier to observe in the frequency domain.
If sampling is done at a rate fast enough to faithfully approximate the original waveform (usually five times
the highest frequency component in the signal), the resulting discrete data series will uniquely describe
the analog signal. This is of particular value when dealing with transient signals, which conventional swept
spectrum analyzers cannot handle.
While FFT has become a popular analysis tool, some care must be taken with it. In most instances,
incorrect positioning of the signal within the display grid will significantly alter the spectrum, producing
effects such as leakage and aliasing that distort the spectrum.
An effective way to reduce these effects is to maximize the acquisition record length. Record length
directly conditions the effective sampling rate and therefore determines the frequency resolution and
span at which spectral analysis can be carried out.

Setting Up FFT
1. Follow the usual steps to set up a math function, selecting FFT from the Frequency Analysis
submenu.
2. Open the FFT subdialog.
3. Choose an Output type.
4. If your Output Type is Power Density or Power Spectrum, also enter Line Impedence. By default,
the FFT function assumes a termination of 50 Ohms. If an external terminator is being used, this
setting can be changed to properly calculate the FFT based on the new termination value.
If your Output type is Phase, enter a Group Delay Shift value.
5. Optionally, choose a weighting Window (see below).
6. Check the Suppress DC box to make the DC bin go to zero. Otherwise, leave it unchecked.

Choosing a Window
The choice of a spectral window is dictated by the signal's characteristics. Weighting functions control the
filter response shape, and affect noise bandwidth as well as side lobe levels. Ideally, the main lobe should
be as narrow and flat as possible to effectively discriminate all spectral components, while all side lobes
should be infinitely attenuated. The window type defines the bandwidth and shape of the equivalent filter
to be used in the FFT processing.
Rectangular windows provide the highest frequency resolution and are useful for estimating the type of
harmonics present in the signal. Because the rectangular window decays as a (sinx)/x function in the
spectral domain, slight attenuation will be induced. Functions with less attenuation (Flat Top and
Blackman-Harris) provide maximum amplitude at the expense of frequency resolution, whereas Hamming
and Von Hann are good for general purpose use with continuous waveforms.

117

WaveRunner 8000 Oscilloscopes Instruction Manual
Window Type

Applications and Limitations

Rectangular

Normally used when the signal is transient (completely contained in the time-domain window)
or known to have a fundamental frequency component that is an integer multiple of the fundamental frequency of the window. Signals other than these types will show varying amounts of
spectral leakage and scallop loss, which can be corrected by selecting another type of window.

Hanning (Von Hann)

Reduces leakage and improves amplitude accuracy. However, frequency resolution is also
reduced.

Hamming

Reduces leakage and improves amplitude accuracy. However, frequency resolution is also
reduced.

Flat Top

Provides excellent amplitude accuracy with moderate reduction of leakage, but with reduced
frequency resolution.

Blackman-Harris

Reduces leakage to a minimum, but with reduced frequency resolution.

Math and Measure

Interpolate Function
Linear interpolation, which inserts a straight line between sample points, is best used to reconstruct
straight-edged signals such as square waves. This is the default interpolation method used by the
oscilloscope.
(Sinx)/x interpolation, on the other hand, is suitable for reconstructing curved or irregular waveshapes,
especially when the sampling rate is 3 to 5 times the system bandwidth.
Cubic interpolation can be used to create a smooth, continuous function by applying a third-degree
polynomial.
For each method, you can select an upsample factor of 2 to 50 points to insert between samples.
1. Follow the usual steps to set up a math function, selecting Interpolate from the Filter submenu.
2. Touch Algorithm and select an interpolation type.
3. Enter the Upsample factor by which to increase sampling.
You can use the Up and Down buttons to set this value. To make fine increment changes, deselect
the "only by 2, 5..." checkbox.
4. In Half Width enter the width in taps of the filter.
5. To use a weighting function rather than an upsample factor, select it from Weighting. See FFT for
more information about the functions. If using the Kaiser function, also enter the Beta value.

Sparse Function
The Sparse math function allows you to thin out an incoming waveform by skipping points at regular
intervals, and by starting acquisition at a particular offset (point). The Sparsing factor specifies the
number of sample points to reduce the input waveform by. A sparsing factor of 4, for example, says to
retain only one out of every 4 samples. A Sparsing offset of 3, on the other hand, says to begin on the third
sample, then skip the number of samples specified by the sparsing factor (4). In this way, the sample rate
is effectively reduced.
For the sparsing factor (interval), you can set a value from 1 to 1,000,000 points. For the sparsing offset
you can set a value from 0 to 999,999.
1. Follow the usual steps to set up a math function, selecting Sparse from the Misc submenu.
2. Touch the Sparsing factor control and provide a Bandwidth Limit value.
3. Touch the Sparsing offset control and provide a value.

Rescale Function and Assigning Units
The Rescale function allows you to apply a multiplication factor (a) and additive constant (b) to any source
waveform. You can do it in the unit of your choice, depending on the type of application.
Tip: Analog channel traces may be rescaled directly using the Cx dialogs. They do not require a
separate Math function.

Setting Up Rescaling
1. Follow the usual steps to set up a math function, selecting Rescale from the Functions submenu.
2. Touch the Rescale subdialog tab.
3. To apply a multiplication factor:
l

Check the First multiply by: box and enter a value for a, the multiplication factor.

Touch then add: and enter a value for b, the additive constant.

4. To change the output unit of measure from that of the source waveform:
l

Check Override units.

In Output enter the abbreviation for the new unit of measure.

You can combine units following these rules:
l

For the quotient of two units, use the character ":/"

For the product of two units, use the character "."

For exponents, append the digit to the unit without a space (e.g., "S2" for seconds squared)
Note: Some units are converted to simple units (e.g., V.A becomes W).

Phistogram Function
The Phistogram function creates a histogram of the samples within a vertical or horizontal "slice" of a
persistence map to reveal the features that are only visible when several acquisitions have been
superimposed on one another. Vertically, each bin contains a class of similar amplitude levels; horizontally,
each bin contains a class of similar time values.
The source trace must have Persistence "on" to generate the persistence map. Eye diagrams, which are a
type of persistence map, are a an especially useful class of traces to which you can apply the Phistogram
function.
For a histogram of...

Use...

A crossover point in time or amplitude on an eye diagram *

Vertical and horizontal slice persistence histogram

Cumulative jitter on an eye diagram *

Horizontal slice persistence histogram

Signal-to-noise ratio on an eye diagram *

Vertical slice persistence histogram

* Requires optional software package capable of creating eye diagrams, such as SDA II orSerial Decoder TDME software.

1. Follow the usual steps to set up a math function, choosing a Single operator function using the
Phistogram operator.
2. On the Phistogram subdialog, choose the slice of the persistence map to histogram:
l

Slice Direction of determines whether the slice transverses the entire height of the map
centered around a time (vertical), or transverses a period of time in the map centered around
a level (horizontal).

Slice Center represents the center time or level of the slice.

Slice Width represents the total time or amplitude of the slice, half each side of the center.
l

Note: This operation does not affect, and is not affected by, Center and Width settings
made on any existing histograms.

3. Choose Center Cursor to place a measurement cursor at the center of the slice.

Ptrace Functions
The Ptrace Mean, Ptrace Range, and Ptrace Sigma math functions (found in the Jitter Functions submenu of the Math Operator selector) compute a vector trace based on a persistence map of underlying
signal acquisitions without destroying the underlying data, allowing the display of analytical results from
raw data. Further measurements or Pass/Fail testing can be performed on the resulting function traces.

List of Standard Operators
The math operators included standard with your oscilloscope are listed below alphabetically.
Note: There may be additional operators available depending on the software options installed on
the oscilloscope.
Operator

Definition

Absolute

For every point in the waveform the distance away from zero is calculated. For values greater
than zero this is the same as the value. For values less than zero, the magnitude of this value
without regard to its sign is used.

Average

Calculates either a summed or continuous average of a selected number of sweeps. See Averaging Waveforms. The maximum number of sweeps is determined by the oscilloscope model
and memory.

Copy

Copies waveform in its unprocessed state to the first available memory location.

Correlation

Calculates a measure of similarity of two waveforms, or a waveform against itself, as a function
of a time-lag applied to one of them.

Derivative

Calculates the derivative of adjacent samples using the formula:
(next sample value – current sample value) / (horizontal sample interval)

Deskew

Shifts trace in time the amount of the deskew factor.

Difference

For every point in the waveform, the value of Source2 is subtracted from the value of Source1.
Source1 and Source2 must have the same horizontal units and scale and the same vertical
units.

Envelope

Calculates highest and lowest vertical values of a waveform at each horizontal value for a specified number of sweeps.

ERes

Applies a noise reduction and smoothing filter by adding a specified number of bits. See
Enhanced Resolution.

Exp

Calculates the antilog to the base e of the source; that is, e raised to the power equal to the
source.

Exp10

Same as Exp, using base 10.

FFT

Computes a frequency spectrum with optional Rectangular, Von Hann, Flat Topp, Hamming,
Blackman-Harris, and Hanning windows. Calculates up to 128 Mpts. Also allows FFT Averaging through use of a second math operator. See FFT.

Floor

Calculates the lowest vertical values of a waveform at each horizontal value for a specified number of sweeps.

Histogram

Plots the number of data points that fall into statistically significant intervals or bins. Bar height
relates to the frequency at which data points fall into each interval/bin.

Integral

Calculates the linearly rescaled integral (with multiplier and adder) of a waveform input starting
from the left edge of the screen using the formula:
(current sample value + next sample value) * (horizontal sample interval)
Each calculated area is summed with the previous sum of areas. The multiplier and adder are
applied before the integration function.

Interpolate

Inserts points between sampled points (upsamples) according to one of three algorithms: Linear (straight line), Sinx/x (curved), and Cubic (spine). Interpolation factor of 2 to 50 determines
number of points in the upsample.

Invert

For every point in the waveform, the inverse of that point is calculated.

Produces a waveform using a custom MatLab function.

Phistogram

Creates a histogram based on the displayed pixels of a persistence map falling within a userdefined vertical and/or horizontal box (slice). The source trace must have Persistence turned
"on."

Product

For every point in the waveform, the value of Source1 is multiplied by the value of Source 2.
Source1 and Source2 must have the same horizontal units and scale.

Ptrace mean

Plots the mean value of each sample point in a persistence map. The source trace must have
Persistence turned "on."

Ptrace range

Generates a waveform with a width derived from the population range of a persistence map.
The source trace must have Persistence turned "on."

Ptrace sigma

Generates a waveform with a width derived from the sigma (sum) of a persistence map. The
source trace must have Persistence turned "on."

Ratio

For every point in the waveform, the value of Source1 is divided by the value of Source2.
Source1 and Source2 must have the same horizontal units and scale.

Reciprocal

For every point in the waveform the inverse is calculated using the formula:
1 / (sample value)

Rescale

For every point in the waveform the sample value is multiplied by the specified multiplier and
then add to with the specified adder. See Rescaling and Assigning Units.

Roof

Calculates the highest vertical values of a waveform at each horizontal value for a specified
number of sweeps.

Segment

Selects one segment from a source waveform to place in a sequence waveform. Used in
Sequence sampling mode.

Sinx/x

Performs 10-to-1 interpolation using a Sin(x)/x filter.

Sparse

“Thins,” or decimates, an incoming acquisition by dropping sample points at regular intervals.
Sparsing factor specifies the number of points to drop between retained samples (e.g., factor of
4 retains 1 then drops 4). Sparsing offset specifies the point at which to begin applying the
sparsing factor (e.g., offset of 3 begins count on the third sample (3), then drops the number of
samples specified by the sparsing factor (4).

Square

For every point in the waveform, the square of the sample value is calculated.

Square Root

For every point in the waveform, the square root of the sample value is calculated.

Sum

For every point in the waveform, the value of Source1 is added to the value of Source 2.
Source1 and Source2 must have the same horizontal units and scale and the same vertical
units.

Track

Generates a waveform composed of parameter measurements that is time synchronous with
the source waveform. The vertical units are those of the source parameter value and the horizontal units are seconds. Parameter values are posted at the sampling rate.

Trend

Produces a waveform composed of a series of parameter measurements in the order the measurements were taken. The vertical units are those of the source parameter, the horizontal unit is
measurement number. The trend contains a single value for each measurement.

Zoom

Produces a magnified trace of a selected portion of the input waveform. See Zooming Traces.

WaveRunner 8000 Oscilloscopes Instruction Manual

Memory
The instrument is equipped with four internal memory slots (Mx) to which you can copy any waveform
that is active on the grid. This is a convenient way to store an acquisition for later viewing and analysis.
Memories can be used as source inputs for most oscilloscope math and measurements, allowing you to
compare historical data to a live acquisition or perform "what if" modeling on saved acquisitions.

Saving Memories
Store memories on the Memory dialogs (Mx). Memories are created at the same scale as the source
trace, but they can be adjusted independently by using the zoom factor controls that appear next to the
Mx dialogs.

Save Waveform to Memory
Tip: Try to choose an empty slot, as anything currently stored in that location will be overwritten.
All memories will state if they are empty or an acquisition is stored there.
Touch the Add New box and choose Memory until you see an empty memory slot. Drag the descriptor box
of the trace you wish to store onto the Mx descriptor box.
Or
1. Press the front panel Mem button or choose Math > Memory Setup to open the Memories dialog.
2. Touch the Mx tab corresponding to the memory slot you wish to use.

3. In Copy from Waveform, choose the source trace to copy to memory.
4. Touch Copy Now.
5. Optionally, check Trace On to immediately display the memory. Use the Zoom controls to adjust
the scale of the memory trace.

Save (External) Waveform Files to Memory
Trace (.trc) files saved on other Teledyne LeCroy instruments can also be saved to internal memory. Use
the Recall Waveform function to save external files to memory. Then, you can use the Memories dialog to
restore them to the touch screen.

126

Math and Measure

Restoring Memories
The Memories dialog is a convenient panel for restoring saved memories to the display.
Access the Memories dialog by pressing the front panel Mem button or choosing Math > Memory Setup.

Analysis Tools

Analysis Tools
The Analysis menu tools complement the standard math and measurements to help you understand the
behavior of waveforms.
WaveScan searches single or multiple acquisitions for events that meet specific criteria.
Pass/Fail Testing shows whether waveforms or measurements meet a set of defined criteria.
Optional software packages may be purchased for specialized uses, such as power analysis. In most
cases, these options are added to the Analysis menu. Documentation for software options can be found at
teledynelecroy.com/support/techlib under Manuals > Software Options. In addition, documentation for
many options available on your platform can be found in the online Help under the Support menu.

WaveScan
The WaveScan® Search and Find tool enables you to search for unusual events in a single capture, or to
scan for a particular event in many acquisitions over a long period of time. Each Scan Mode is optimized to
find a different type of event. Results are time stamped, tabulated, and can be viewed individually.

WaveScan window with different scan "views" turned on.

You customize the presentation by choosing different WaveScan displays, called Scan Views. Optionally,
set actions, such as stopping or beeping, to occur automatically when unusual events are found.

129

WaveRunner 8000 Oscilloscopes Instruction Manual
Note: The instrument reverts to Real-time sampling mode when WaveScan is enabled.

Setting Up WaveScan
Set up your source channel and triggers before setting up the scan.

1. Press the front panel Stop button to stop acquisition.
2. Choose Analysis > WaveScan.
3. Check Enable.
4. Choose the Source waveform.
5. Choose the Scan Mode and enter values for any additional settings that appear at the right of the
dialog based on your selection.
6. Select each Scan View in which you wish to display results by checking the box at the bottom of the
dialog. Each view selected is displayed simultaneously.
7. If you're using Scan Overlay view, on the Scan Overlay dialog Clear Sweeps. If desired, set up the
Persistence display.
8. Optionally, choose an Action to trigger when an event that meets your scan criteria is found.
9. Restart acquisition.

Scan Modes
The Scan Mode determines the type of search to be performed. Select the Mode along with the Source
trace to be searched on the main WaveScan dialog. For each mode, different controls appear on the
WaveScan dialog, providing additional inputs to the search criteria. Make the appropriate entries in these
fields before starting the search.

Edge Mode
Edge Mode is used for detecting the occurrence of edges. Events that meet the threshold level are
captured and tabulated. When the acquisition is stopped, scan filters can be applied to the edges to find
specific characteristics. Edge Mode settings are:
l

Slope. Choose Pos, Neg, or Both.

Level is (set in...). Choose Percent or Absolute.

Percent/Absolute Level. Enter a threshold value as a percentage of Top to Base or voltage level.

130

Analysis Tools

Non-monotonic Mode
Non-monotonic Mode looks for edges that cross a threshold more than once between high and low levels.
All events that meet the criteria of slope, hysteresis, and level are presented in a table and highlighted in
the source trace. The value displayed in the table is the difference of the max. and min. of the nonmonotonicity. This can be confirmed with cursors. The hysteresis value is used to eliminate noise. A nonmonotonicity is detected only when its amplitude is greater than the hysteresis. Therefore, when setting a
hysteresis level, set a value that is greater than the amplitude of the noise. Settings are:
l

Slope. Choose Pos, Neg, or Both.

Hysteresis is (set in...). Choose Division, Percent, Absolute.

Division/Percent/Absolute. Enter hysteresis level in the selected unit.

Levels are (set in...). Choose Percent, Absolute, or Pk-Pk%.

High/Low Level. Enter top and bottom thresholds in the selected unit.

Runt Mode
Runt Mode looks for pulses that fail to cross a specified threshhold. You can search for positive-going or
negative-going runts, or both. An adjustable hysteresis band is provided to eliminate noise.
In the case of negative-going runt pulses, the value displayed in the table is the difference (delta) of the
high level of the signal and the runt amplitude (i.e., where the runt bottoms out). This can be confirmed by
placing cursors on the runt pulse and reading the delta Y value in the trace labels. In the case of positivegoing runt pulses, the value displayed in the table is the absolute value of the amplitude of the runt pulse.
Runt Mode settings are:
l

Runt Type. Choose Both, Pos, or Neg.

Hysteresis. Enter the hysteresis level as a percentage or voltage.

Low/High Threshold. Enter the levels as a percentage or voltage.

Absolute Levels. Check this box to enter levels as absolute voltage instead of percentage.

Measurement Mode
Measurement Mode is used for applying filters to measurements to find those that meet your defined
criteria, helping to isolate particular events within many samples. Markers appear over the source trace to
indicate the location of measurement, while the table displays values for the selected parameter that
meet the criteria. Measurement Mode settings are:
l

Measurement. Choose the measurement parameter you wish to search.
Filter Method. Choose the operator that indicates the desired relationship to the Filter Limit. Only
measurements that meet this criteria are returned.
Filter Limit. Enter the value that completes the filter criteria.

Alternatively, you can use the Filter Wizard to create the filter criteria.

131

WaveRunner 8000 Oscilloscopes Instruction Manual

Serial Pattern Mode
Serial Pattern Mode is used for finding 2- to 64-bit patterns in digital sequences; ideal for bursted patterns
where a PLL cannot lock. Serial Pattern Mode settings are:
l

Viewing. Choose to enter the pattern as Binary or Hex(adecimal).

Binary/Hex. Enter the pattern.

Num. Patterns to detect. Enter a whole number.

Bus Pattern Mode
Bus Pattern Mode (-MS models only) is used for finding 2- to 16-bit patterns across the digital lines. Bus
Pattern Mode settings are:
l

Viewing. Choose to enter the pattern as Binary or Hex(adecimal).

Binary/Hex. Enter the pattern.

Num. Patterns to detect. Enter a whole number.

Scan Views
Scan Views are different ways to view your WaveScan results. Just check the boxes at the bottom of the
WaveScan dialog for those views you wish to display simultaneously.
Note: The number of grids varies depending on which views are enabled. WaveScan handles this
function automatically, and you cannot move traces among grids as in normal operation.
Additional controls for Scan Overlay and Zoom views are on their respective dialogs. If you turn on these
traces from those dialogs, you must turn them off from there, too.

Source Trace
By default, the source trace is displayed in the top grid, with markers indicating points that meet the
search criteria.

Table
Table view displays a table of measurements relevant to your chosen Search Mode next to the source
trace. Times view adds columns to the table showing Start and Stop Times for each event.

Scan Overlay
Scan Overlay view uses colored overlays to show the location of events meeting the criteria.

Zoom
Zoom view works exactly as it does elsewhere in the X-Stream software, creating a new trace that is a
magnified section of the source trace. A Zx tab appears by default when you launch WaveScan; see zoom
factor controls for an explanation of the remainder of the controls found on this dialog.

132

Analysis Tools

Scan Overlay
To apply monochromatic persistence to a Scan Overlay:
1. Select Scan Overlay when setting up the wave scan, then open the Scan Overlay dialog.
2. Check Persistence On.
3. Enter a Saturation level as a percentage. All samples above the saturation level are assigned the
highest color intensity.
4. Choose a Persistence Time. The higher the time, the more static the persistence display.
To adjust the scan overlay to "zoom" in or out: touch the In/Out buttons, or touch Scale and enter new
values. Check Var. to adjust scale in finer steps than the default 1, 2, 5.

Scan Histogram
Scan Histogram is an additional WaveScan "view" that generates a histogram to give you a statistical view
of edges that meet your search criteria. Set it up as you would any histogram:
1. Enter the total #Values in the histogram buffer.
2. Enter the #Bins (bars) in the histogram.
3. Enter the Center value and Width of each bin from center, or check Enable Auto Find and let the
sofware Find Center and Width.
4. Choose a Vertical Scale method:
l

Linear allows the histogram to build vertically as data accumulates. When the histogram
reaches the top of the display it rescales the vertical axis to keep it on screen.
LinConstMax keeps the histogram at near full scale and rescales the vertical axis as data is
accumulated.

133

WaveRunner 8000 Oscilloscopes Instruction Manual

WaveScan Search
Search is used to find events in traces—usually zoom (Zx) traces—that match user-defined criteria. To
search within WaveScan:
1. Select the Zoom view.
2. After stopping the acquisition, open the Zx dialog that appears behind the WaveScan dialog.
3. Use the Prev and Next buttons to move back or forward within the trace to the events that
matched your Scan Modes criteria.
Or
If you know the WaveScan table index (row) number of the event you wish to find, enter it in Idx.

134

Analysis Tools

Pass/Fail Testing
Pass/Fail testing allows you to define a set of qualifying conditions that an acquisition may "pass" or "fail"
when tested against, then take actions depending on whether the result is a pass or a fail.
l

Mask testing compares sampled values to a pre-defined area of the grid (the "mask") to see if they
fall within or without.
Parameter comparison compares a measurement result to a pre-defined value (Param compare) or
to another measurement (Dual param compare).

You can preconfigure eight qualifiers (Qx) using either method, which are then enabled by selecting them
on the Pass/Fail dialog and defining what results constitute a "Pass" on the Actions dialog.

Mask Test Qualifiers
A mask defines an area of the grid against which a source Channel, Zoom, or Math trace is compared.
Test conditions are associated with the mask, defining how the waveform is to be compared to the
masked area (e.g., some/all values fall within, some/all values fall outside), and a pass or fail result is
returned indicating the condition was found to be true or false.
Mask testing can be done using a pre-defined mask or a mask created from a waveform with user-defined
vertical and horizontal tolerances. Some industry standard masks used for compliance testing are
included with the oscilloscope software. The mask test can be confined to just a portion of the trace by
the use of a measure gate.

Access Mask Test Dialogs
1. Choose Analysis > Pass/Fail to display the Pass/Fail dialog.
2. Touch the Qx button where you want to set up the qualifier.
3. Select Mask test.
The Qx dialog opens with the Mask test condition selected and the Test, Load Mask, Make Mask, and
Gate subdialogs displayed. On these dialogs, you manage, make, and apply gates to your mask.

135

WaveRunner 8000 Oscilloscopes Instruction Manual

Make Mask
Use this procedure to create a new mask based on a live waveform. The mask covers the area of the
waveform plus the boundaries you enter.
1. Open the Make Mask subdialog.
2. If desired, enter a new Destination File Name and path, or touch Browse and select a previous file
to overwrite. The file name should end with the .msk extension.
3. Touch the Ver Delta and Hor Delta fields and enter boundary values using the pop-up Virtual
Keypad or the front panel Adjust knob.
4. Touch Make from Trace.

Load Mask
Use this procedure in lieu of Make Mask if you have a pre-defined mask file.
1. Open the Load Mask subdialog.
2. To use a saved .msk file, touch File and select the mask.
To use an industry standard mask, touch Standard and select the mask from the pop-up.
3. Check View Mask to display the mask over the trace.

Remove a Mask from the Display
Touch the Delete All Masks button on the Load Mask subdialog. Alternatively, open the Qx dialog where a
particular mask is set, and on the Load Mask subdialog, touch Delete.

Set Gates
Set gates to limit the portion of the waveform that is compared to the mask.
1. Open the Gate subdialog.
2. Enter the Start and Stop horizontal divisions that mark the segment of the waveform to be tested
with this mask. This can be a whole division or a fraction of a division. Divisions are numbered 1-n
left to right.
A quick way to position the gate is to drag the gate posts initially placed at the extreme left and right
ends of the grid to the desired points.

Define "True"
1. Open the Test subdialog.
2. Select one of the conditions that, when true (yes), results in a pass.
3. Optionally, turn On markers to show where on the waveform mask violations have occurred.

136

Analysis Tools

Param(eter) Compare Qualifiers
Pass/Fail qualifiers (Qx) can be configured to compare different parameter measurements (Px) to each
other or to a user-defined limit (or statistical range). The Summary field shows the logic represented by
the qualifier. Check it to ensure your selections are producing the test you want.

Comparing a Measurement to a Limit
This method compares the result of a selected parameter to a user-defined limit or statistical range.
1. Choose Analysis > Pass/Fail to display the Pass/Fail dialog.
2. Touch the Qx button where you want to set up a qualifier.
3. From the pop-up menu, choose Param compare.
4. On the Qx dialog, touch Source1 and choose the parameter.

5. On the ParamCompare subdialog, touch Compare Values and select All (every value must be
within limit to be "true") or Any (any value can be within limit to be "true").
6. Touch Condition and select a math operator, then touch Limit and enter the value that completes
the condition. The value entered acquires properties corresponding to the parameters being
tested. For example, if you are testing a time parameter, the unit is seconds.
7. If you chose to set a Delta limit, also enter the Absolute or % Delta value. You may choose instead
to set Limit and Delta using one of the buttons at the bottom of the dialog.

Comparing Parameter Measurements
This method compares one parameter to another, rather than a limit.
1. Choose Analysis > Pass/Fail to display the Pass/Fail dialog.
2. Touch the Qx button where you want to set up a qualifier.
3. From the Pass/Fail Condition menu, choose Dual Param Compare.
4. On the left-hand Qx dialog, select the parameters to compare in Source1 and Source2.
5. On the ParamCompare subdialog, choose to Compare All (every value must meet condition to be
"true") or Any (any value can meet condition to be "true").
6. Touch Condition and select the operator that expresses the relationship between parameters (e.g.,
All P1 values must be less than P2).

137

WaveRunner 8000 Oscilloscopes Instruction Manual

Define Pass/Fail Tests
The Qualifiers define the conditions that would result in "true" but don't in themselves determine the test
result. You must separately define what constitutes a "pass" or a "fail" on the Actions dialog. A Pass or Fail
result can be made to produce various additional actions, such as sending a pulse to another device.
1. After setting up the Pass/Fail test qualifiers, open the Actions tab.

2. Optionally, check Summary View to see a running summary of results over the total number of
sweeps.
3. Select the test Pass criteria in Pass If.

Saving Data (File Functions)

LabNotebook
The LabNotebook feature allows you to create and save composite files containing a screen capture of all
displayed waveforms, as well as all waveform and setup data at the time of capture.
LabNotebooks can be output to a preformatted .PDF, .RTF, or .HTML report. You can also upload your
own report layout if you prefer not to use the default.
The Flashback feature instantly recalls the setups and waveforms stored with LabNotebook Entries,
enabling you to restore the exact state of the instrument at a later date to perform additional analysis.

Save LabNotebook
All LabNotebook files (.LNB) are composed of a screen image (.PNG), a setup file (LSS), and a waveform
file (.TRC) for each waveform displayed. When creating LabNotebooks, you choose how to handle the
screen image component, which is the basis for the Report Generator output, and to which you can add a
description and other hand-drawn annotations.
1. Choose File > Save LabNotebook from the menu bar.

2. Optionally, enter a Description. This text appears whenever the file is recalled and on reports.

display update rate. Choices are presented as a spectrum.
There are also tabs linking to Calibration, Acquisition, Color, and Miscellaneous settings.

166

Utilities

Calibration
Calibration ensures that the output from the analog-to-digital converters (ADCs) accurately represents the
input. The instrument is calibrated at the factory prior to shipment. So that it maintains specified
performance, it is factory set to perform an automatic calibration routine upon start-up and whenever
conditions warrant it, based on your automatic calibration selection.
To maintain good performance, we recommend that you manually invoke a full calibration every six
months.
Warm up the oscilloscope for at least 20 minutes prior to use to give the instrument time to complete the
automatic calibration procedure. You will see a warning message on the Calibration dialog when the
oscilloscope is still in the warm-up phase.

Automatic Calibration
You have the option of selecting the automatic calibration routine used. Go to Utilities > Preference
Setup > Calibration.
Stored Calibration (the default selection) uses cached calibration files to recalibrate the instrument at
start-up. As long as the oscilloscope is used at or near sea level within a temperature range of 19-30 °C,
this calibration routine should be sufficient to maintain specified performance. The instrument will
dynamically recalibrate if the temperature goes outside of the stored calibration range. If you know you
will be operating outside this temperature range, do a Calibrate All to minimize recalibration.
The Dynamic Calibration routine recalibrates the oscilloscope at start-up and every time there is a
change in any of the acquisition settings that directly affect the performance of the ADCs, in particular
Vertical Scale, Coupling, Bandwidth, Attenuation, and Horizontal Scale. This can cause interruptions during
operation, but ensures absolute accuracy within the current operating environment at every setting. When
one setup is calibrated at a particular ambient temperature, the calibration is entered in a calibration table
and reused for the duration of the session, so that over time the frequency of recalibration decreases.
These calibration entries persist only for a single session; Dynamic Calibration restarts when the
instrument is restarted or you change the principal acquisition settings.

Manual Calibration
Two manual calibration routines can be used to recalibrate immediately before sensitive measurements
or when there is a significant change of environmental characteristics that could affect the performance
of the ADCs.
Go to Utilities > Preference Setup > Calibration to manually invoke calibration.
Caution: Remove all inputs from the oscilloscope prior to manual calibration.

167

WaveRunner 8000 Oscilloscopes Instruction Manual
Calibrate Current State calibrates at the current vertical and horizontal settings. This calibration takes 5
seconds but is valid for only this setup at the current temperature ±2.5 °C.
Calibrate All calibrates all possible combinations of vertical and horizontal settings. This calibration is valid
for the current temperature and takes about four to five hours. Perform it when the ambient temperature
is stable from the time of calibration to the time of operation.
We recommend that you run Calibrate All when:
l

The instrument is operating outside the 19-30 °C range and the operating temperature changes
while outside that range. Calibrate All is only valid for ± 2.5 °C of the last calibration temperature when
operating outside of the 19-30 °C range.

The instrument is moved to a new operating environment.

It has been six months since the previous manual calibration.

168

Utilities

Acquisition
The Acquisition preference settings determine how traces behave as Vertical Offset or Horizontal Delay
changes. To access them, choose Utilities > Preference Setup and open the Acquisition dialog.
Offset Setting constant in:
l

Volts moves the Vertical Offset level indicator with the actual voltage level.
Div(isions) keeps the Vertical Offset level indicator stationary. The waveform remains on the grid as
you increase the gain; whereas, if Volts is selected, the waveform could move off the grid.

Delay Setting constant in:
l

Time moves the Horizontal Delay indicator relative to the 0 point at the center of the grid.
Div(isions) keeps the Horizontal Delay indicator stationary. The trigger point remains on the grid as
you increase the timebase; whereas, if Time is selected, the trigger point could move off the grid.
Note: The Offset value is always in the vertical unit, and the Delay is always in time. However,
whenever Div is selected, these values are scaled proportional to the change in gain or timebase,
thereby keeping the division of the grid constant.

Reset trigger counter before starting a new acquisition is selected by default. It clears the trigger
counter each time a new acquisition command is sent. It is only made active for deselection when trigger
Holdoff is set.

Control Sensitivity adjusts the sensitivity of the front panel knobs. Optimized applies an acceleration
algorithm to the knobs. Legacy detects rotation of the front panel knobs in a manner similar to our legacy
oscilloscopes.
Serial Decode Annotation Position: If you have Serial Trigger or Decode options installed on your
instrument, this control determines the placement of annotation labels relative to the trace line. It does
not appear if there are no installed options.
l

On Trace places the label close to the line.
On Noisy Trace sets the label further from the line to accommodate potential noise spikes in the
trace.

Check Enable HTTP Screen Capture to enable remote capture of the touch screen display over a
netowrk. This setting is required to use the instrument with the WaveStudio software.
