Performance Verification
Procedures
TDS 500C, TDS 600B & TDS 700C Performance Verification and Specifications 1–1
Performance Verification Procedures
Two types of Performance Verification procedures can be performed on this
product: Brief Procedures and Performance Tests. You may not need to perform
all of these procedures, depending on what you want to accomplish.
HTo rapidly confirm that the oscilloscope functions and was adjusted properly,
just do the brief procedures under Self Tests, which begin on page 1–5.
Advantages: These procedures are quick to do, require no external
equipment or signal sources, and perform extensive functional and accuracy
testing to provide high confidence that the oscilloscope will perform
properly. They can be used as a quick check before making a series of
important measurements.
HTo further check functionality, first do the Self Tests just mentioned; then do
the brief procedures under Functional Tests that begin on page 1–7.
Advantages: These procedures require minimal additional time to perform,
require no additional equipment other than a standard-accessory probe, and
more completely test the internal hardware of the oscilloscope. They can be
used to quickly determine if the oscilloscope is suitable for putting into
service, such as when it is first received.
HIf more extensive confirmation of performance is desired, do the Perform-
ance Tests, beginning on page 1–15, after doing the Functional and Self Tests
just referenced.
Advantages: These procedures add direct checking of warranted specifica-
tions. They require more time to perform and suitable test equipment is
required. (See Equipment Required beginning on page 1–16).
If you are not familiar with operating this oscilloscope, read the TDS 500C,
TDS 600B & TDS 700C Reference (070-9861-XX) or the TDS 500C, TDS 600B
& TDS 700C User Manual (070-9869-XX). These contain instructions that will
acquaint you with the use of the front-panel controls and the menu system.

Brief Procedures
The Self Tests use internal routines to confirm basic functionality and proper
adjustment. No test equipment is required to do these test procedures.
The Functional Tests utilize the probe-compensation output at the front panel as
a test-signal source for further verifying that the oscilloscope functions properly.
A probe is required to do these test procedures.
Self Tests
This procedure uses internal routines to verify that the oscilloscope functions and
was adjusted properly. No test equipment or hookups are required.

Brief Procedures
TDS 500C, TDS 600B & TDS 700C Performance Verification and Specifications 1–7
Functional Tests
The purpose of these procedures is to confirm that the oscilloscope functions
properly. The only equipment required is one of the standard-accessory probes
and, to check the file system, a 3.5 inch, 720 K or 1.44 Mbyte floppy disk.
CAUTION. The P6243 and P6245 probes that can be used with this oscilloscope
provide an extremely low loading capacitance (<1 pF) to ensure the best
possible signal reproduction. These probes should not be used to measure
signals exceeding ±8 volts, or errors in signal measurement will be observed.
Above 40 volts, damage to the probe may result. To make measurements beyond
±10 volts, use either the P6139A probe (good to 500 volts peak), or refer to the
catalog for a recommended probe.
STOP. These procedures verify functions; that is, they verify that the oscilloscope
features operate. They do not verify that they operate within limits.
Therefore, when the instructions in the functional tests that follow call for you to
verify that a signal appears on-screen “that is about five divisions in amplitude”
or “has a period of about six horizontal divisions,” etc., do NOT interpret the
quantities given as limits. Operation within limits is checked in Performance
Tests, which begin on page 1–15.
STOP. DO NOT make changes to the front-panel settings that are not called out
in the procedures. Each verification procedure will require you to set the
oscilloscope to certain default settings before verifying functions. If you make
changes to these settings, other than those called out in the procedure, you may
obtain invalid results. In this case, just redo the procedure from step 1.
When you are instructed to press a menu button, the button may already be
selected (its label will be highlighted). If this is the case, it is not necessary to
press the button.

Performance Tests
This section contains a collection of procedures for checking that the TDS 500C,
TDS 600B, and TDS 700C Digitizing Oscilloscopes perform as warranted.
The procedures are arranged in four logical groupings: Signal Acquisition System
Checks, Time Base System Checks, Triggering System Checks, and Output Ports
Checks. They check all the characteristics that are designated as checked in
Specifications. (The characteristics that are checked appear in boldface type
under Warranted Characteristics in Specifications).
STOP. These procedures extend the confidence level provided by the basic
procedures described on page 1–5. The basic procedures should be done first,
then these procedures performed if desired.
Prerequisites
The tests in this section comprise an extensive, valid confirmation of perform-
ance and functionality when the following requirements are met:
HThe cabinet must be installed on the digitizing oscilloscope.
HYou must have performed and passed the procedures under Self Tests, found
on page 1–5, and those under Functional Tests, found on page 1–7.
HA signal-path compensation must have been done within the recommended
calibration interval and at a temperature within ±5_ C of the present
operating temperature. (If at the time you did the prerequisite Self Tests, the
temperature was within the limits just stated, consider this prerequisite met).
HThe digitizing oscilloscope must have been last adjusted at an ambient
temperature between +20_ C and +30_ C, must have been operating for a
warm-up period of at least 20 minutes, and must be operating at an ambient
temperature between +4_ C and either +45_ C for the TDS 600B or +50_ C
for the TDS 500C and 700C. (The warm-up requirement is usually met in
the course of meeting the Self Tests and Functional Tests prerequisites listed
above).

1Two plus Two channel operation allows up to two of the four channels to be
displayed simultaneously. Channels not displayed can be used to couple a
triggering signal to the oscilloscope.
User Interface
Use a combination of front-panel buttons, knobs, and on-screen menus to control
the many functions of the oscilloscope. The front-panel controls are grouped
according to function: vertical, horizontal, trigger, and special. Set a function you
adjust often, such as vertical positioning or the time base setting, directly by its
own front-panel knob. Set a function you change less often, such as vertical
coupling or horizontal mode, indirectly using a selected menu.
Pressing one (sometimes two) front-panel button(s), such as vertical menu,
displays a main menu of related functions, such as coupling and bandwidth, at
the bottom of the screen. Pressing a main-menu button, such as coupling,
displays a side menu of settings for that function, such as AC, DC, or GND
(ground) coupling, at the right side of the screen. Pressing a side-menu button
selects a setting such as DC.
On-screen readouts help you keep track of the settings for various functions,
such as vertical and horizontal scale and trigger level. Some readouts use the
cursors or the automatic parameter extraction feature (called measure) to display
the results of measurements made or the status of the instrument.
Assign the general purpose knob to adjust a selected parameter function. More
quickly change parameters by toggling the SHIFT button. Use the same method
as for selecting a function, except the final side-menu selection assigns the

TDS 500C, TDS 600B & TDS 700C Performance Verification and Specifications 2–3
general purpose knob to adjust some function, such as the position of measure-
ment cursors on screen, or the setting for a channel fine gain.
The user interface also makes use of a GUI, or Graphical User Interface, to make
setting functions and interpreting the display more intuitive. Some menus and
status are displayed using iconic representations of function settings, such as
those shown here for full, 250 MHz and 20 MHz bandwidth. Such icons allow
you to more readily determine status or the available settings.
Signal Acquisition System
The signal acquisition system provides four, full-featured vertical channels with
calibrated vertical scale factors from 1 mV to 10 V per division. All channels can
be acquired simultaneously.
Each of the full-featured channels can be displayed, vertically positioned, and
offset, can have their bandwidth limited (250 MHz or 20 MHz) and their vertical
coupling specified. Fine gain can also be adjusted.
Besides these channels, up to three math waveforms and four reference wave-
forms are available for display. (A math waveform results when you specify dual
waveform operations, such as add, on any two channels. A reference waveform
results when you save a waveform in a reference memory).
Horizontal System
There are three horizontal display modes: main only, main intensified, and
delayed only. You can select among various horizontal record length settings.
A feature called “Fit to Screen” allows you to view entire waveform records
within the 10 division screen area. Waveforms are compressed to fit on the
screen. See Table 2–2.
Both the delayed only display and the intensified zone on the main intensified
display may be delayed by time with respect to the main trigger. Both can be set
to display immediately after the delay (delayed runs after main mode). The
delayed display can also be set to display at the first valid trigger after the delay
(delayed-triggerable modes).
The delayed display (or the intensified zone) may also be delayed by a selected
number of events. In this case, the events source is the delayed-trigger source.
The delayed trigger can also be set to occur after a number of events plus an
amount of time.

Trigger System
The triggering system supports a varied set of features for triggering the
signal-acquisition system. Trigger signals recognized include:
HEdge (main- and delayed-trigger systems): This familiar type of triggering is
fully configurable for source, slope, coupling, mode (auto or normal), and
holdoff.
HLogic (main-trigger system): This type of triggering can be based on pattern
(asynchronous) or state (synchronous). In either case, logic triggering is
configurable for sources, for Boolean operators to apply to those sources, for
logic pattern or state on which to trigger, for mode (auto or normal), and for
holdoff. Time qualification may be selected in pattern mode. Another class
of logic trigger, setup/hold, triggers when data in one trigger source changes
state within the setup and hold times that you specify relative to a clock in
another trigger source.
HPulse (main-trigger system): Pulse triggering is configurable for triggering
on runt or glitch pulses, or on pulse widths or periods inside or outside limits
that you specify. It can also trigger on a pulse edge that has a slew rate faster
or slower than the rate you specify. The timeout trigger will act when events
do not occur in a defined time period. The pulse trigger is also configurable
for source, polarity, mode, and holdoff.
HVideo (with option 05: Video Trigger): Video triggering is compatible with
standard NTSC, PAL, SECAM, and HDTV formats. An additional feature
called FlexFormatTM (flexible format) allows the user to define the video
format on which to trigger.
HComm (with option 2C): is provided for triggering on AMI, CMI, or NRZ
communications signals.
You can choose where the trigger point is located within the acquired waveform
record by selecting the amount of pretrigger data displayed. Presets of 10%,
50%, and 90% of pretrigger data can be selected in the horizontal menu, or the
general purpose knob can be assigned to set pretrigger data to any value within
the 0% to 100% limits.
Acquisition Control
You can specify a mode and manner to acquire and process signals that matches
your measurement requirements.
HSelect the mode for interpolation (linear or sin (x)/x). This can increase the
apparent sample rate on the waveform when the maximum real-time rate is
exceeded.
Specifications
2–6 TDS 500C, TDS 600B & TDS 700C Performance Verification and Specifications
HUse sample, envelope, average and peak detect modes to acquire signals.
With the TDS 500C/700C, also use high-resolution mode.
HSet the acquisition to stop after a single acquisition (or sequence of
acquisitions if acquiring in average or envelope modes) or after a limit
condition has been met.
HSelect channel sources for compliance with limit tests. You can direct the
TDS to signal you or generate hard copy output either to a printer or to a
floppy-disk file based on the results. Also, you can create templates for use
in limit tests.
On-Board User Assistance
Help and autoset can assist you in setting up the digitizing oscilloscope to make
your measurements.
Help displays operational information about any front-panel control. When help
mode is in effect, manipulating any front-panel control causes the digitizing
oscilloscope to display information about that control. When help is first
invoked, an introduction to help is displayed on screen.
Autoset automatically sets up the digitizing oscilloscope for a viewable display
based on the input signal.
Measurement Assistance
Once you have set up to make your measurements, the cursor and measure
features can help you quickly make those measurements.
Three types of cursors are provided for making parametric measurements on the
displayed waveforms. Horizontal bar cursors (H Bar) measure vertical parame-
ters (typically volts). Vertical bar cursors (V Bar) measure horizontal parameters
(typically time or frequency). Paired cursors measure both amplitude and time
simultaneously. These are delta measurements; that is, measurements based on
the difference between two cursors.
Both H Bar and V Bar cursors can also be used to make absolute measurements.
For the H Bars, either cursor can be selected to read out its voltage with respect
to any channel’s ground reference level. For the V Bars, the cursors measure time
with respect to the trigger point (event) of the acquisition. The cursors can also
control the portion of the waveform on which automatic measurements are made.

Cursor
Specifications
TDS 500C, TDS 600B & TDS 700C Performance Verification and Specifications 2–7
For time measurements, units can be either seconds or hertz (for 1/time).
With the video trigger option installed (Option 05), you can measure the video
line number using the vertical cursors. You can measure IRE amplitude (NTSC)
using the horizontal cursors with or without the video trigger option installed.
Measure can automatically extract parameters from the signal input to the
digitizing oscilloscope. Any four out of the 25 parameters available can be
displayed to the screen. The waveform parameters are measured continuously
with the results updated on-screen as the digitizing oscilloscope continues
to acquire waveforms.
An important component of the multiprocessor architecture of this digitizing
oscilloscope is Tektronix’s proprietary digital signal processor, the DSP. This
dedicated processor supports advanced analysis of your waveforms when doing
such compute-intensive tasks as interpolation, waveform math, and signal
averaging. It also teams with a custom display system to deliver specialized
display modes (See Display, later in this description).
Storage
Acquired waveforms may be saved in any of four nonvolatile REF (reference)
memories or on a 3.5 inch, DOS 3.3-or-later compatible disk. Any or all of the
saved waveforms may be displayed for comparison with the waveforms being
currently acquired.
The TDS 500C/700C instrument with option HD or option 2M can save
waveforms to an internal hard disk drive. Any or all of the saved waveforms
may be displayed for comparison with the waveforms being currently acquired.
The source and destination of waveforms to be saved may be chosen. You can
save any of the four channels to any REF memory or move a stored reference
from one REF memory to another. Reference waveforms may also be written
into a REF memory location via the GPIB interface.
I/O
The oscilloscope is fully controllable and capable of sending and receiving
waveforms over the GPIB interface (IEEE Std 488.1–1987/IEEE Std 488.2–1987
standard). This feature makes the instrument ideal for making automated
measurements in a production or research and development environment that
calls for repetitive data taking. Self-compensation and self-diagnostic features
built into the digitizing oscilloscope to aid in fault detection and servicing are
also accessible using commands sent from a GPIB controller.

The oscilloscope can also output copies of its display using the hardcopy feature.
This feature allows you to output waveforms and other on-screen information to
a variety of graphic printers and plotters from the TDS front panel, providing
hard copies without requiring you to put the TDS into a system-controller
environment.
You can make hardcopies in a variety of popular output formats, such as PCX,
TIFF, BMP, RLE, EPS, Interleaf, and EPS mono or color. You can also save
hardcopies in a disk file in any of the formats listed in the I/O section.
The hardcopies obtained are based on what is displayed on-screen at the time
hardcopy is invoked. The hardcopies can be stamped with date and time and
spooled to a queue for printing at a later time. You can output screen information
via GPIB, RS-232C, or Centronics interfaces.
Display
The TDS 500C, TDS 600B and TDS 700C Digitizing Oscilloscopes offer
flexible display options. You can customize the following attributes of your
display:
HColor (TDS 644B, TDS 684B, and TDS 700C): Waveforms, readouts,
graticule, and variable persistence with color coding
HIntensity: waveforms, readouts, and graticule
HStyle of waveform display(s): vectors or dots, intensified or nonintensified
samples, infinite persistence, and variable persistence
HInterpolation method: Sin(x)/x or Linear
HDisplay format: xy or yt with various graticule selections including NTSC
and PAL to be used with video trigger (option 05)
This oscilloscope also provides an easy way to focus in on those waveform
features you want to examine up close. By invoking zoom, you can magnify the
waveform using the vertical and horizontal controls to expand (or contract) and
position it for viewing.

is the smallest voltage level change of the oscilloscope input that can be resolved by the 8-bit A-D Converter. Expressed
as a voltage, a DL is equal to 1/25 of a division times the volts/division setting.
2The sensitivity ranges from 1 mV/div to 10 V/div (for 1 M) or to 1 V/div (for 50 ) in a 1–2–5 sequence of coarse settings
with Fit-to-Screen off. Between coarse settings, the sensitivity can be finely adjusted with a resolution equal to 1% of the
more sensitive coarse setting. For example, between 50 mV/div and 100 mV/div, the volts/division can be set with 0.5 mV
resolution.

2The range of waveform rates for interpolated (or equivalent-time on the TDS 700C) waveform records.
3The Waveform Rate (WR) is the equivalent sample rate of a waveform record. For a waveform record acquired by
real-time sampling of a single acquisition, the waveform rate is the same as the real-time sample rate; for a waveform
created by interpolation of real-time samples from a single acquisition or, on applicable products, the equivalent-time
sampling of multiple acquisitions, the waveform rate created is faster than the real time sample rate. For all these cases,
the waveform rate is 1/(Waveform Interval) for the waveform record, where the waveform interval (WI) is the time between
the samples in the waveform record.

TDS 600B: For the averaged condition, 1.4 ≤ Tr/Wi ≤ 40, where Wi is the Waveform
Interval, as described elsewhere in these specifications.
TDS 600B: Extra error in the measurement will occur for two-channel measurements due
to channel-to-channel skew. This is described elsewhere in these specifications.

1The limits given are for the ambient temperature range of 0_C to +30_C. Reduce the upper bandwidth frequencies by
5 MHz for the TDS 600B or by 2.5 MHz for the TDS 500C/700C for each _C above +30_C.
2The numbers given are valid 0_C to +30_C and will increase as the temperature increases due to the degradation in
bandwidth. Rise time is calculated from the bandwidth. It is defined by the following formula:
Note that if you measure rise time, you must take into account the rise time of the test equipment (signal source, etc.) that
you use to provide the test signal. That is, the measured rise time (RTm) is determined by the instrument rise time (RTi) and
the rise time of the test signal source (RTgen) according to the following formula:
TDS 600B Rise Time (ns)+450
BW (MHz)
RTm2+RTi2)RTgen 2
TDS 500Cń700C Rise Time (ns)+400
BW (MHz)
3The values given are the maximum absolute difference between the value at the end of a specified time interval after the
midlevel crossing of the step and the value one second after the midlevel crossing of the step, expressed as a percentage
of the step amplitude.

1The trigger position errors are typically less than the values given here. These values are for triggering signals having a
slew rate at the trigger point of ≥0.5 division/ns.
2The waveform interval (WI) is the time between the samples in the waveform record. Also, see the footnote for the
characteristics Sample Rate Range or Interpolated Waveform Rates in Table 2–4, on page 2–10.
3The minimum sensitivity for obtaining a stable trigger. A stable trigger results in a uniform, regular display triggered on the
selected slope. The trigger point must not switch between opposite slopes on the waveform, and the display must not
“roll” across the screen on successive acquisitions. The TRIG’D LED stays constantly lighted when the SEC/DIV setting is
2 ms or faster but may flash when the SEC/DIV setting is 10 ms or slower.
4The minimum signal levels required for stable logic or pulse triggering of an acquisition, or for stable counting of a
DC-coupled, events-delay signal. Also, see the footnote for Sensitivity, Edge-Type Trigger, DC Coupled in this table. (Stable
counting of events is counting that misses no events and produces no extra, phantom events).

5The minimum signal levels required for stable runt pulse triggering of an acquisition. Also, see the footnote for Sensitivity,
Edge-Type Trigger, DC Coupled in this table. (Stable counting of events is counting that misses no events).
6The minimum signal levels required for stable pulse width or glitch triggering of an acquisition. Also, see the footnote for
Sensitivity, Edge-Type Trigger, DC Coupled in this table. (Stable counting of events is counting that misses no events).
7For Logic, time between channels refers to the length of time a logic state derived from more than one channel must exist
to be recognized. For Events, the time is the minimum time between a main and delayed event that will be recognized if
more than one channel is used.
8For Slew Rate Triggering, this is the minimum transition time, defined to be the time the user’s signal spends between the
two trigger threshold settings.
9User Hold Time is the number selected by the user in the Hold Time Menu.
