This manual uses certain conventions that you should become familiar with.
Some sections of the manual contain procedures for you to perform. To
keep those instructions clear and consistent, this manual uses the following
conventions:
Instructions for menu selection follow this format:
*
" "' '&&#" "' '&&#". For example, Press
%#" %& &#
&#$)
."
Names of front panel controls and menus appear in the same case
(initial capitals, all uppercase, etc.) in the manual as is used on the
AWG2005 front panel and menus. Front panel names are all upperĆcase
letters; for example, , etc.
Instruction steps are numbered unless there is only one step.
#' %
Throughout this manual, any replaceable component, assembly, or part of
the AWG2005 is referred to generically as a module. In general, a module is
an assembly (like a circuit board), rather than a component (like a resistor or
an integrated circuit). Sometimes a single component is a module; for
example, the chassis of the AWG2005 is a module.

H
PowerĆon and powerĆoff cycles
To ensure proper AWG2005 operation and long life, note these environmenĆ
tal requirements.
The AWG2005 operates in an environment with an ambient air temperature
between +10_ĂC and +40_ĂC. The AWG2005 storage temperature ranges
from -20_ĂC to +60_ĂC. After storage at temperatures outside the operating
limits, allow the AWG2005 chassis to stabilize at a safe operating temperaĆ
ture before applying power.
Air drawn in and exhausted through the cabinet side and bottom panels
cools AWG2005 internal circuits. To ensure proper cooling, allow the followĆ
ing clearances:
Top and back
Left and right
7.6Ăcm (3 in.)
15Ăcm (6 in.)
The feet on the bottom of the AWG2005 cabinet provide the required clearĆ
ance when it is set on a flat surface. The top of the AWG2005 does not
require ventilation clearance.
CAUTION
To prevent temporary shutdown of the AWG2005, do not restrict air
flow through the chassis. If the AWG2005 shuts down unexpectedly,
improve ventilation around the AWG2005 and wait a few minutes to
allow it to cool down; then switch the power on again.
!
2Ć1
Before installing the AWG2005, note these precautions:
WARNING
To avoid equipment failure and potential fire or personal shock
hazards, do not exceed the maximum rated operating voltage of
250ĂV between the voltageĆtoĆground (earth) and either pole of the
power source. The AWG2005 operates from a singleĆphase power
source and has a threeĆwire power cord with a twoĆpole, threeĆterĆ
minal grounding plug. Also, before making connection to the power
source, be sure the AWG2005 has a suitable twoĆpole, threeĆtermiĆ
nal groundingĆtype plug.
To avoid personal shock hazard, do not contact conductive parts.
All accessible conductive parts are directly connected through the
grounding conductor of the power cord to the grounded (earthing)
contact of the power plug. The AWG2005 is safety Class 1 equipĆ
ment (IEC designation).
To avoid personal shock hazard, do not defeat the grounding
connection. Insert the power input plug only in a mating receptacle
with a grounding contact where earth ground has been verified by a
qualified service person. Also, for electricalĆshock protection, make
the grounding connection before making connection to the
AWG2005 input or output terminals.
The AWG2005 ships with the required power cord as ordered by the cusĆ
tomer. Table 2Ć1 gives the colorĆcoding of the conductors in the power cord.
Figure 2Ć1 shows information on the available power cords.

A lithium battery maintains internal nonvolatile memory, allowing the
AWG2005 to retain waveform and sequence files if AC power is lost. This
battery has a shelf life of about three years. Partial or total loss of stored
information at powerĆon may indicate that the battery needs to be replaced.
WARNING
To avoid risk of fire or explosion, replace the AWG2005 battery with
a lithium battery having the part number listed in section 10, MeĆ
chanical Parts List. This battery is a safetyĆcontrolled part.
To avoid risk of fire or explosion, do not recharge, rapidly disĆ
charge, or disassemble the battery; and do not incinerate the
battery or heat it above 100°ĂC. Also, dispose of used batteries
promptly. Small quantities of used batteries can be disposed of in
normal refuse. Keep lithium batteries away from children.
Your AWG2005 may include one or more options. To determine which opĆ
tions are installed, power on the AWG2005 and look at the display during
the powerĆon sequence. The AWG2005 lists the installed options after OpĆ
tions, near the top of the display.
Table 2Ć1 of this subsection gives information about line cord options. SecĆ
tion 7, Options, lists other options and optional accessories. For further
information and prices of options, see your Tektronix Products catalog or
contact a Tektronix Field Office.
2Ć6
Before servicing the AWG2005, read the following operating instructions.
These instructions are at the level appropriate for servicing the AWG2005.
The user manual contains complete operator instructions.
In addition, section 4, Performance Verification, includes instructions for
making the frontĆpanel settings required to check AWG2005 characteristics.
To powerĆon the AWG2005, follow these steps:
1. Set the PRINCIPAL POWER SWITCH (on the back of the AWG2005) to
the ON position. This switch is the main power switch; it routes power to
the standby circuit in the AWG2005.
2. Then, press the ON/STBY (standby) switch on the front (lowerĆleft corĆ
ner) of the AWG2005. This switch applies power to the remaining circuits
of the AWG2005. Allow at least 20 minutes for the AWG2005 to warm up.
WARNING
To avoid personal shock hazard, turn off both the ON/STBY switch
and the PRINCIPAL POWER SWITCH before servicing. The PRINCIĆ
PAL POWER SWITCH on the rear panel is the true power disconĆ
nect switch. The ON/STBY (standby) switch simply toggles
operation on and off. When connected to a power source and when
the PRINCIPAL POWER SWITCH is on, the internal power supplies
and much of the other circuitry of the AWG2005 remain energized
regardless of the setting of the ON/STBY switch.
To avoid personal shock hazard, set the PRINCIPAL POWER
SWITCH off before connecting or disconnecting the line cord to or
from the power source.
At powerĆon, the AWG2005 performs internal startĆup diagnostics. These
diagnostics check internal circuit function and report any failures. In addiĆ
tion, you can initiate internal diagnostics; these diagnostics differ from the
startĆup diagnostics in that they do more extensive memory checking.
The AWG2005 also contains internal calibration routines, which check
internal circuit function and adjust calibration constants. Run these calibraĆ
tion routines whenever the AWG2005 undergoes a temperature change. For
2Ć7
Instructions for Operation
instance, run the calibration routines after the AWG2005 warms up at powerĆ
on. This warmup period and subsequent calibration assures AWG2005
operation at optimum performance levels.
User Interface
The AWG2005 uses a combination of frontĆpanel buttons, keys, a knob, and
onĆscreen menus to control generator functions. Some frontĆpanel controls
select menus and manipulate menu items. Others enter values and units,
allow manual triggering, and turn on/off AWG2005 output. OnĆscreen graphĆ
ics show various aspects of the current AWG2005 configuration.
OnĆscreen menus set all AWG2005 functions except manual triggering and
output control. Main menus provide access to lowerĆlevel nested submenus.
Buttons in the center of the front panel select the main menus.
When you select a menu, the display shows the items controlled by that
menu and numeric values currently in effect. Buttons around the display
select lowerĆlevel menus, change menu selections, modify numeric values
and units, and execute functions.

The AWG2005 generates waveform output from four different types of waveĆ
form files:
2Ć11
Instructions for Operation
Waveform Storage
and I/O
. This is the basic waveform data file.
It contains the waveform data that the AWG2005 loads into memory and
reads when generating waveform output. The data in this kind of file can
be created using the waveform editor, generated from equations made
using the equation editor, transferred in over an interface, or directly
transferred in from certain Tektronix instruments. In addition, the waveĆ
form editor displays the data in a waveform data file in three formats:
graphical, table, and timing.
. The waveform equation file
contains equations that express waveform characteristics. Compilation
of the waveform equation file generates a waveform data file. The
AWG2005 generates the waveform output from this file.
. The waveform sequence file
specifies a series of waveform data files. When the AWG2005 executes a
waveform sequence file, it sequentially generates waveforms from each
waveform data file, in the order specified.

fies a series of waveform data files and/or waveform sequence files.
When the AWG2005 executes a waveform autostep file, it generates the
waveform for the first file specified. Then it waits for a trigger before
generating from the next specified file. The autostep file includes output
conditions for each channel.
The AWG2005 has both internal memory and internal nonvolatile memory
(NVRam) for waveform file storage. The AWG2005 generates waveforms
from files residing in internal memory. To save a file that is in internal
memory, copy it to nonvolatile memory or floppy disk. Only nonvolatile
memory retains files at powerĆoff.
The AWG2005 also has a floppyĆdisk drive for loading files from floppy disk
into internal memory or internal nonvolatile memory and for saving files from
either memory to floppy disk. The disk drive accepts 3.5Ćinch MSĆDOSĆforĆ
matted floppy disks.
Loading Files
The following steps explain how to load files from a floppy disk into internal
memory.
1. Push the LOAD/SAVE button in the MENU column.
2. Turn the disk so the side with the arrow is on top; insert the disk into the
AWG2005 floppy disk drive.

Setting Output
Parameters
The SETUP menu allows you to set various output parameters for outputting
a waveform or sequence waveform. To set the output parameters, select a
waveform or sequence file (that is already loaded into memory) as the active
file.
When you select a file, the AWG2005 changes to the output parameters
associated with the file and displays these parameters on the SETUP menu.
If you modify the displayed output parameters and later save the file, the
modified output parameters are saved with the file. (if the file is locked, you
cannot modify the file contents.)

setting.
2Ć14
! !
The following explains each item in the bottom menu.
Ċ This item sets the clock source and clock frequency. The
clock source can be set to either internal or external.
The clock period is the time between the data points for the waveĆ
form created. Therefore, the product of the clock period and the
number of waveform points is the waveform or sequence period. For
example, if the clock frequency is 1 MHz (period of 1 µs) and there
are 100 waveform points, the waveform period is displayed as 100
ms.
The clock source and clock frequency setting will be applied to all
channels.
Ċ This item performs an arithmetic operation between
the CH1 waveform and CH2 waveform or external waveform, and
outputs the result at the CH1 output connector. The operations are
addition (Add, External Add) and multiplication (AM, External AM).
Ċ This item selects a filter that restricts the frequency band
for the output channel. Choose a 5, 2, 1 MHz, or 500ĂkHz filter, or
you can select Through (no filter).
Ċ This selection sets the voltage value for the 12Ćbit, fullĆ
scale, output amplitude on the vertical scale. The amplitude can be
set in steps of 1ĂmV within the range from 0.05ĂV to 10ĂV.
Ċ This item sets the offset level of the output waveform. The
offset can be set in steps of 5ĂmV within the range ±5ĂV.
The MODE menu initiates the waveform output with the output conditions
set using the SETUP menu.
1. Push the
button in the MENU column. The MODE menu in
Figure 2Ć6 appears.
2. Select the operation mode from the bottom menu. The operation modes
are Cont, Triggered, Gated, Waveform Advance, and Autostep.
In all modes except Cont, the trigger or gate signal source can be the
external signal applied to the TRIGGER INPUT connector or can be
generated by pushing the front panel TRIGGER MANUAL button. The
following text describes the individual modes.
!
Ċ When you push the Cont button, the AWG2005
immediately outputs the specified waveform or sequence waveform
continuously.
2Ć15
#"
Ċ In triggered mode, the AWG2005 outputs the
specified waveform or sequence waveform once, when a trigger
occurs.
Ċ In gated mode, the gate signal controls the waveĆ
form or sequence output.
As long as the front panel MANUAL button is pushed, (or the gating
signal is high) the AWG2005 outputs the specified waveform or
sequence. When the MANUAL button is released (or the gating
signal goes low), the waveform output stops. When the MANUAL
button is pushed again, the output resumes from the level at which
the waveform or sequence output stopped.
! ! Ċ When a sequence file has been
designated in the SETUP menu, Waveform Advance mode is used
to advance a waveform in sequence each time a trigger is received.
The waveform output conditions in waveform advance mode can be
set to either or depending on the selection for the
side menu item.
2Ć16
Instructions for Operation
Continuous Ċ In this mode, the first waveform is output over and
over again for each channel when a trigger signal is received. When
the next trigger signal is received, output of the first waveform stops
after the end point of that waveform and then the second waveform
is output in the same manner. The next waveform is not started at
the moment a trigger is received, but rather at the completion of the
previous waveform.
In this way, waveforms are output for each channel one by one in
sequence each time a trigger signal is received. When a trigger
signal is received while output of the last waveform is in progress,
the output stops at the end point of that waveform and then the
process begins again from output of the first waveform.
Step Ċ In this mode, the first waveform is output on each channel
when a trigger signal is received, but only for the number of times
set with Repeat in the sequence editor. The next waveform is output
when the next trigger signal is received. Other operations are the
same as Continuous output.
Autostep Mode Ċ Use Autostep mode to start an Autostep file
created with the EDIT menu Autostep editor. An Autostep file stores
a program that specifies a waveform or sequence file (including
output parameters) for each channel for each step.
Autostep mode resembles Waveform Advance mode in which each
time a trigger is received, the display advances one waveform.
However, in this mode the output parameters for each waveform
change as well. The operating mode for each step can be set with
the waveform output conditions to either Continuous or Step, as in
the case of Waveform Advance mode. Just as in other operating
modes, the Autostep mode trigger signal can be generated from the
external trigger signal or by pressing the front panel MANUAL butĆ
ton.
Continuous Ċ In this mode the programmed Step:1 waveform is
output over and over again when a trigger signal is received. When
the next trigger signal is received output of the Step:1 waveform
stops after the end point of that waveform and then the Step:2
waveform is output in the same manner. The waveform is started at
the moment a trigger is received.
In this way, the current waveforms advance for each channel one by
one in sequence each time a trigger signal is received. When a
trigger signal is received while output of the last waveform in the
step is in progress, the output stops at the end point of that waveĆ
form and then the process begins again from output of the Step:1
waveform.
AWG2005 Service Manual
2Ć17
Instructions for Operation
Step Ċ When a trigger signal is received, the Step:1 waveform for
each channel is output once. When the next trigger signal is reĆ
ceived, the Step:2 waveform is output (once). When the next trigger
signal is received while waveform output is in progress, output stops
after the end point of that waveform and then the waveform for the
next step is output.
3. Set the trigger (gate) conditions for the external trigger (gate) source.
The external trigger (gate) signal is input from the TRIGGER INPUT
connector on the front panel. The input impedance is 10 kW and the
maximum input voltage is "10 V.
When an operating mode other than Cont is selected, the AWG2005
displays a side menu for selecting the trigger (gate) conditions for
the external trigger (gate) source. The following describes each of
these items.
2Ć18
Slope Ċ This item sets the slope for external trigger signals. To
Polarity (Gated Mode) Ċ This item sets the polarity for the gate
Level Ċ This item sets the external trigger (gate) signal level. To set
this parameter push the side menu Level button, then use the nuĆ
meric keys or the general purpose knob to change the value. The
trigger (gate) level can be set in steps of 0.1ĂV within the range from
-5.0ĂV to 5.0ĂV.
select a positive or negative slope, push the side menu Slope butĆ
ton. For a positive slope, the AWG2005 applies the trigger at the
rising edge of the external trigger signal; for a negative slope, the
trigger is applied at the falling edge of the external trigger signal.
that outputs the waveform or sequence based on the level of the
external gate signal. To set the polarity, push the side menu Polarity
button. For a positive polarity, the AWG2005 outputs the waveform
or sequence waveform while the gate signal level is higher than the
gate level parameter set with the side menu Level item. For negative
polarity, waveform output occurs while the gate signal level is lower.
Operating Information
Theory of Operation
This section describes the basic operation of the major circuit blocks or
modules in the AWG2005. Section 9, , includes two block diaĆ
grams and an interconnect diagram. Figure 9Ć1 shows the modules and
functional blocks of the AWG2005 with Option 02, 04, 05 and 09 installed.
Figure 9Ć2 shows how the modules interconnect.
Module Overview
The module overview describes the basic operation of each functional circuit
block.
The AWG2005 Arbitrary Waveform Generator is a portable, twoĆ or fourĆ
channel instrument. For each channel, the AWG2005 reads the digital waveĆ
form data loaded into its waveform memory. The point rate clock determines
the rate at which the data is read. The AWG2005 converts the data from
digital to analog format and outputs the resulting arbitrary waveform.
Clock Oscillator (A1 Clock Board)
The clock circuit is a PLL oscillator that uses a 12.8 MHz reference crystal. It
supplies a point rate clock that is adjustable from 20 MHz to 0.01 Hz for
reading data from channel waveform memory.
When an external clock source is selected, the external clock signal is
passed directly through to the Clock board and used for reading waveform
data in memory.
Clock Sweep Oscillator (A31 Clock Sweep Board)
In addition to the description for the Clock Sweep Oscillator, it provides the
clock sweep from 20 MHz to 0.03 Hz.
Sequencer (A2 AWG Board)
This sequencer block controls the waveform memory addresses read out
according to the contents of a sequence file.
Waveform Memory (A2 AWG Board)
This functional block contains the memory that holds the waveform digital
data. There are 12 bits for waveform data and one bit for waveform markers
(for each channel).
AWG2005 Service Manual

Theory of Operation
DigitalĆtoĆAnalog Converter (DAC) (A11 D/A Board)
This functional block is a 12Ćbit highĆspeed digitalĆtoĆanalog converter. It
converts the digital data from the waveform memory into analog signals.
Analog Processing (A3/A23 Analog Board)
This analog processing block amplifies the analog signals from the DAC to
the necessary amplitude. If an offset is specified, this circuit adds that offset
and outputs the result at the output connector for that channel. This circuit
also contains a filter, an AM modulator, and other elements that modify
waveform output. Its output impedance is 50 W.
CPU and Memory (A6 CPU Board)
This functional block directs operation of all internal circuits, based on front
panel control operation and commands received over the GPIB or RSĆ232ĆC
interface. This circuit includes the 68000 CPU, DRAM, EPROM, SRAM. Data
in memory is retained by a lithium battery on the A5 Backplane board.
CAUTION
To avoid losing waveform data files stored in NVRam, save the files
to a floppy disk before removing the A6 CPU board or A5 BackĆ
plane board. Then restore the files from floppy disk to AWG2005
NVRam after reinstalling the board(s).
GPIB (A6 CPU Board)
This functional block is the General Purpose Interface Bus (GPIB) interface
driver, which controls communication with external devices over the parallel
interface. The GPIB connector is on the rear panel.
RSĆ232ĆC (A6 CPU Board)
This functional block is the RSĆ232ĆC interface circuit which controls serial
communication with external devices over the RSĆ232ĆC interface. The
RSĆ232ĆC interface connector is on the rear panel.
Display Control (A6 CPU Board)
The display control block processes the test and waveform information
based on commands from the processor. The block sends the text and
waveform information to the display monitor as video signals with vertical
and horizontal sync control.

Display Monitor
The display monitor takes in the video signals and displays them on a
17.8Ăcm (7 in.) CRT screen. The display resolution is 480 640 pixels.
Front Panel (A12 Key Board)
The front panel block includes the buttons, keys, knobs, and so on, for
entering selections. User selections from the front panel are sent to the
processor. The buttons at the bottom and side of the display are also inĆ
cluded in this block. Commands from the processor control the LED in the
buttons.
Floppy Disk Drive
The 3.5Ćinch floppy disk drive supports both 2DD and 2HD MSĆDOS forĆ
mats.
Low Voltage Power Supply
This functional block is a switchingĆtype power supply that converts the line
voltage into the various voltages required for internal circuit operation.
Fan
The fan prevents heat buildĆup inside the cabinet; it pulls air into the right
(floppyĆdisk) side of the AWG2005 and exhausts it out the left side.

Theory of Operation
Options
The following four options which modify AWG2005 operation are available.
Option 02: CH3 and CH4 Output Channels
Option 04: Digital Data Out
Option 05: Clock Sweep
This option provides an additional function: the clock sweep editor. In
addition to performing linear sweep and log sweep for the clock freĆ
quency, the clock sweep editor enables you to easily create arbitrary
sweep. The Clock board for the AWG2005 standard type is replaced by
the Clock Sweep board.
Option 09: Floating Point Processor
This option adds CH3 and CH4 waveform output channels. It includes
an AWG board, a D/A board and an Analog board for Channel 3 and 4.
This option directly outputs the digital data in the waveform memory
without passing it through the digitalĆtoĆanalog converter. This option
and Option 09 cannot both be installed.
This option is a card dedicated to floating point processing. It provides
the capability to edit in the frequency domain and it speeds up internal
calculations.
For more information about these and other options, see section 7, .

Performance Verification
Self Tests
This subsection describes how to use AWG2005 internal selfĆtest routines.
No equipment is required to do these procedures. The self tests include
these internal routines:
Diagnostics
This selfĆtest procedure uses internal routines to verify that the
AWG2005 functions, and passes the internal circuit tests.
Calibration
The second procedure checks the AWG2005 internal calibration
constants and changes them if needed.
Diagnostics
The internal diagnostic routines check AWG2005 characteristics such as
amplitude, offset, trigger level, clock, filters and attenuation.
The AWG2005 automatically performs the internal diagnostics at powerĆon;
you can also run the internal diagnostics using the menu selections deĆ
scribed in this procedure. The difference between these two methods of
initiating the diagnostics is that the menu method does more detailed
memory checking than the powerĆon method.

The AWG2005 doesn't need manual adjustment since it is equipped with a
self calibration system.. This internal calibration enables the instrument to
automatically adjust the gain and offset of the pre-amp, the gain error of
filter, the attenuation rate of attenuator, as well as several other parameters.
Perform the internal calibration to return the AWG2005 to conformance with
performance specified in section 1,
. As for the internal calibraĆ
tion, see the subsection,

Before Maintenance
Preventing ESD
CAUTION
Precautions
When performing service which requires internal access to the AWG2005,
follow these precautions to avoid damaging internal modules and their
components due to electrostatic discharge (ESD).
1. Minimize handling of staticĆsensitive modules.
2. Transport and store staticĆsensitive modules in their staticĆprotected
containers or on a metal rail. Label any package that contains staticĆsenĆ
sitive modules.
3. Discharge the static voltage from your body by wearing a grounded
antistatic wrist strap while handling these modules. Only service staticĆ
sensitive modules at a staticĆfree work station.
4. Do not remove the AWG2005 cabinet unless you have met precaution
number 3, above. Consider all internal modules staticĆsensitive.
5. Do not allow anything capable of generating or holding a static charge
on the work station surface.
6. Handle circuit boards by the edges when possible.
7. Do not slide the modules over any surface.
8. Avoid handling modules in areas that have a floor or workĆsurface coverĆ
ing capable of generating a static charge.
9. Do not use highĆvelocity compressed air when cleaning dust from
modules.

AWG2005 Service Manual
6Ć3
6Ć4
This subsection describes how to determine whether the AWG2005 needs
cleaning, and how to do the cleaning. Inspection and cleaning are prevenĆ
tive maintenance procedures. When done regularly, preventive maintenance
may prevent AWG2005 malfunction and enhance reliability.
Preventive maintenance consists of visually inspecting and cleaning the
AWG2005 and using general care when operating it.
How often to do maintenance depends on the severity of the environment in
which the AWG2005 operates.
The cabinet helps keep dust out of the AWG2005 and is a major component
of the instrument cooling system. The cabinet should normally be in place
when operating the AWG2005. The AWG2005 front cover (optional accessoĆ
ry) protects the front panel and display from dust and damage. Install it
when storing or transporting the instrument.
Inspect and clean the AWG2005 as operating conditions require. The collecĆ
tion of dirt on components inside can cause them to overheat and break
down. (Dirt acts as an insulating blanket, preventing efficient heat dissipaĆ
tion.) Dirt also provides an electrical conduction path that can cause an
instrument failure, especially under highĆhumidity conditions.
WARNING
To avoid personal injury or death due to electric shock, unplug the
power cord from the line voltage source before cleaning the
AWG2005.
6Ć5
CAUTION
To prevent damaging the plastics used in the AWG2005 do not use
chemical cleaning agents. Use only deionized water when cleaning
the menu buttons or frontĆpanel buttons. Use a ethyl alcohol soluĆ
tion as a cleaner, and rinse with deionized water.
To prevent damaging AWG2005 components, do not use highĆpresĆ
sure compressed air when cleaning dust from the interior of the
AWG2005. (High pressure air can cause electrostatic discharge.)
Instead, use low pressure compressed air (about 9 psi).

during external cleaning; use only enough liquid to dampen the
cloth or applicator.
1. Remove loose dust on the outside of the AWG2005 with a lint free cloth.
2. Remove remaining dirt with a lint free cloth dampened in a general
purpose detergentĆandĆwater solution. Do not use abrasive cleaners.
3. Clean the light filter protecting the monitor screen with a lintĆfree cloth
dampened with either ethyl alcohol or, preferably, a gentle generalĆpurĆ
pose detergentĆandĆwater solution.
Inspection Ċ Interior
To access the inside of the AWG2005 for inspection and cleaning, refer to
the Removal and Installation Procedures in this section.

This subsection contains the following:
Preparatory information
A list of equipment required in removing modules
Module locator diagrams for finding each module in the AWG2005
Procedures for removing and reinstalling electrical and mechanical
modules
WARNING
To avoid possible personal injury or damage to AWG2005 compoĆ
nents, read the Preparation for Use subsection in section 2, and
Preventing ESD in the subsection, Before Maintenance. Read the
Safety Summary found near the beginning of this manual before
doing any procedure in this manual.
To avoid possible personal injury or death, disconnect the power
cord from the line voltage source before doing any procedures in
this section.
Section 10, Mechanical Parts List, lists all mechanical parts in the AWG2005.
6Ć9
NOTE
First read the
to understand how the procedures
are organized. Then read
to find out the tools needed
to remove and install modules.
To remove a module, begin by doing the
(on page 6Ć13).
By following the instructions in that procedure, you can remove the desired
module without unnecessarily removing other modules.
The
on page 6Ć13 identifies the procedure for removing
each module. These categories separate the procedures based on their
location in the AWG2005.
on page 6Ć16 describes how to remove
modules without internal access to the AWG2005.
on page 6Ć28 describes how to remove
modules which require internal access to the AWG2005.
The removal of most modules in the AWG2005 requires only a screwdriver
handle mounted with a size TĆ15, Torx screwdriver tip. Use this tool whenĆ
ever a procedure step instructs you to remove or install a screw, unless a
different size screwdriver is specified in that step. The first step of a module
procedure lists all equipment required to remove and reinstall the module.

This subsection contains information and procedures designed to isolate
faulty modules in the AWG2005 Arbitrary Waveform Generator. If these
procedures indicate a module needs to be replaced, follow the
, preceding.
The troubleshooting procedures consist of these flowcharts.
Figure 6Ć25: Primary Troubleshooting Procedure

Figure 6Ć30: Troubleshooting Procedure 2 Ċ A6 CPU Board or FrontĆ
panel Module
Figure 6Ć32: Troubleshooting Procedure 3 Ċ Monitor Module
Figure 6Ć36: Troubleshooting Procedure 4 Ċ Module Isolation
To use these procedures, begin with the Primary Troubleshooting ProceĆ
dure. It prompts you to check various indications of AWG2005 functionality
and directs you to the other troubleshooting procedures.
6Ć57
Troubleshooting
AWG2005
Diagnostics
The AWG2005 has internal diagnostics that verify circuit functionality. The
AWG2005 automatically executes the internal diagnostics at powerĆon. You
can also run the internal diagnostics by using the UTILITY menu. See
below. The difference between the two methods
of running the internal diagnostics routine is that the powerĆon method does
not do as much memory checking.
If the internal diagnostics indicate a test in the internal diagnostics failed,
use the troubleshooting procedures in this subsection to determine which
module to replace.
Checking Diagnostics Tests
Prerequisites Ċ Power on the AWG2005 and allow a 20 minute warmup
before doing this procedure.
1. Push the UTILITYDiag/CalDiagnostics
2. Select All with the general purpose knob.
3. Select Execute from the side menu. This executes all the diagnostics
automatically. As each test finishes, the result is displayed on the
screen.
4. Check the diagnostic test results. If any test failed, go to
on page 6Ć68. The table in the
flowchart shows which module is related to each diagnostic test. If the
tests pass but there is still a problem, go to the
on page 6Ć59.

Option 02
This option provides two additional channels (channel 3 and channel 4).
Also, two additional connectors are added on the rear panel (CH3 MARKER
OUT and CH4 MARKER OUT). The instrument with Option 02 allows you to
simultaneously output four different waveforms.
Option 04
With Option 04, the waveform generator can provide the following digital
signals at the rear panel output connector. This option and Option 09 cannot
both be installed.
Data Output
The data (D0-D11) fed to this instrument's internal D/A converter is buffered
and connected to the output connector. At the same time that the analog
waveform is output, the digital output can be obtained. Output will be at the
TTL level.
Clock Output
The same clock that is fed to this instrument's internal D/A converter is
buffered in the same way as the data and connected to the connector. As in
the case of data output, clock output will be at the TTL level.
Figure 7Ć1 is a block diagram of the digital data output Option 04.

Operation
Basically, operations are in correspondence with analog output for the
AWG2005 arbitrary waveform generator. When a waveform is not being
output, the waveform's initial data may be output to the connector. At this
time, the clock is not generated.
When starting the waveform output, the clock is generated and the data is
updated.
NOTE
Excess output can be generated in the data clock (see Figure 7Ć3)
when loading a new waveform into waveform memory, when resetĆ
ting the waveform memory, or during the hold off.

If a cable is used these waveforms have transmission distortion. It is necesĆ
sary to latch the data with a clock before using the waveform in actual
circuits at the cable receiving side (user side) and to reproduce the waveĆ
form. Delay the clock with the delay line in order to reproduce the data
reliably (see Figure 7Ć6).
