Theory of operation
Theory of operation
This section describes the electrical operation of the AWG5200 Series Arbitrary Waveform Generators.
System overview
The AWG5200 Series Arbitrary Waveform Generators provide various models with different sample rates and numbers of channels.
System block diagram
The picture below is a basic block diagram for a single AWG5200 arbitrary waveform generator channel.
Stable timing is derived from a 10 MHz crystal oscillator. Alternatively, an external 10 MHz reference may be used. The 2.5-5.0 GHz clock
signal from the clock module is common to all AWG5200 channels. Each channel has independent clock timing (phase) adjustment which
is located on the DAC module.
The AWG FPGA waveform players are central to the design. These FPGAs retrieve waveform data from memory, receive clock and trigger
timing, and play out waveform data via an eight-lane high-speed-serial interface (JESD204B) to the DAC.
The DAC creates the waveform. The DAC output has four different paths: DC High Bandwidth (DC thru-path), DC High Voltage, AC direct
(AC thru-path), and AC amplified. Note that the AC signal is single-ended, and has its output at the positive-phase (CH+). The DC paths
are differential.
An AWG module contains two waveform players FPGAs. Each drives two DAC channels. A fully-loaded single AWG module provides
waveform data for four channels. Each DAC module has two channels.
Output bandwidth is a little less than half of the DAC sampling clock frequency. The DAC has a “double-data-rate” (DDR) mode where
the DAC is sampled at both rising and falling edges of the clock, and waveform values are interpolated on the falling-edge sample. This
doubles the image-suppressed bandwidth of the system.

Introduction
This section contains information for technicians to service some parts of the AWG5200 Arbitrary Waveform Generators. If further service
is required, send the instrument to a Tektronix Service Center.
Service prerequisites
To prevent personal injury or damage to the instrument, ensure the following before servicing this instrument:
• Procedures in this manual must be performed by a qualified service person.
• Read the General safety summary and the Service safety summary at the beginning of this manual. (See General safety
summary on page 4) and (See Service safety summary).
• When using this manual for servicing, follow all warnings, cautions, and notes.
• Remove and replace procedures describe how to install or remove a replaceable module.
Performance check interval
Generally, the performance check described in the Specifications and Performance Verification Technical Reference document should be
done every 12 months. In addition, a performance check is recommended after repair.
If the instrument does not meet performance criteria, as shown in the Specifications and Performance Verification Technical Reference
document, repair is necessary.
Electrostatic damage prevention
This instrument contains electrical components that are susceptible to damage from electrostatic discharge. Static voltages of 1 kV to 30
kV are common in unprotected environments.
CAUTION:
Observe the following precautions to avoid static damage:
• Minimize handling of static-sensitive components.
• Transport and store static-sensitive components or assemblies in their original containers, on a metal rail, or on conductive foam. Label
any package that contains static-sensitive assemblies or components.
• Discharge the static voltage from your body by wearing a wrist strap while handling these components. Servicing static-sensitive
assemblies or components should only be performed at a static-free workstation by qualified personnel.
• Nothing capable of generating or holding a static charge should be allowed on the workstation surface.
• Keep the component leads shorted together whenever possible.
• Pick up components by the body, never by the leads.
• Do not slide the components over any surface.
• Avoid handling components in areas that have a floor or work surface covering capable of generating a static charge.
• Do not remove the circuit board assembly from the mounting plate. The mounting plate is an important stiffener, which prevents
damage to surface-mount components.
• Use a soldering iron that is connected to earth ground.
• Use only special antistatic, suction-type or wick-type desoldering tools.
Static discharge can damage any semiconductor component in this instrument.
AWG5200 Series Arbitrary Waveform Generators Service Manual 11
Page 12
Maintenance
Note: A lead-free solder such as SAC 305 is recommended for making repairs in this instrument. Cleaning of rosin residue is not
recommended. Most cleaning solvents tend to reactivate the rosin and spread it under components where it may cause corrosion
under humid conditions. The rosin residue, if left alone, does not exhibit these corrosive properties.
Inspection and cleaning
This section describes how to inspect for dirt and damage and how to clean the exterior of the instrument.
The instrument cover helps keep dust out of the instrument, and is needed to meet EMI and cooling requirements. The cover should be in
place when the instrument is in operation.
Inspection and cleaning, when performed regularly, may prevent the instrument from malfunctioning and enhance its reliability. Preventive
maintenance consists of visually inspecting and cleaning the instrument and using general care when operating it. How often preventive
maintenance should be performed depends on the severity of the environment in which the instrument is used. A proper time to perform
preventive maintenance is just before making any product adjustments.
Inspect and clean the instrument as often as operating conditions require.
Exterior inspection
CAUTION: Do not use chemical cleaning agents that might damage the plastics used in this instrument.
Inspect the outside of the instrument for damage, wear, and missing parts, using the following Table 2 on page 12 as a guide. An
instrument that appears to have been dropped or otherwise abused should be checked thoroughly to verify correct operation and
performance. Immediately repair defects that could cause personal injury or lead to further damage to the instrument.

Calibration
CAUTION: The AWG5200 series has a calibration utility, which does not require any external signals or equipment. This self-cal
does not replace a full factory calibration by Tektronix. The full factory calibration must be performed after any procedure that
opens the front panel or rear panel. Any measurements made after opening the front or rear panel, without performing the full
factory calibration afterward, are invalid.
Factory calibration
The factory calibration must be performed after any procedure module that opens the front panel or rear panel. This calibration can only be
performed by Tektronix personnel. If the front panel or rear panel is opened, a full factory calibration must be performed by Tektronix.
Restore Factory calibration
If you run a self-cal and the results are bad, you can restore the factory cal constants by clicking RESTORE FACTORY CAL in the
Calibration window.
Self-calibration
Run the calibration utility under the following conditions:
• If your application requires optimum performance, you should run the self-calibration utility before performing critical tests if there are
temperature is more than 5 °C above or below the temperature at which the calibration was last run. You must run the complete
self-cal. It takes about 10 minutes. If you abort, it won’t write any new cal constants.
• Always start a self-cal by doing the Calibration initialization. It is a hardware reset; it prepares for calibration.
• LOOP: you can loop the calibration, but it never saves the constants. Loop can help find intermittent problems.
• The screen turns pink when there is an error or failure.
Run self-calibration
To run the calibration utility, proceed as follows:
1. No external signals or equipment is necessary. Allow the instrument to run for at least 20 minutes under the environmental conditions
in which it will operate after calibration. Ensure that the instrument’s internal temperature has stabilized.
2. Open the Calibration window:
a. Select the Utilities workspace tab.
b. Select the Diag & Cal button.
c. Select the Diagnostics & Calibration button.
AWG5200 Series Arbitrary Waveform Generators Service Manual 15
Page 16
Maintenance
d. Select the Calibration button, then the Calibration check box to select all self-calibrations, and change the Log options as
desired. All available tests and adjustments are selected now.
3. Click Start to begin the calibration. The Start button changes to Abort while the calibration is in process.
4. During calibration, you can click the Abort button to stop the calibration and revert to the previous calibration data. If you do so, no
calibration constants will be saved.
5. If you allow the calibration to complete, and there are no errors, the new calibration data is applied and saved. The pass/fail result is
shown in the right panel of the Calibration page, and contains the associated date, time, and temperature information.
6. Calibration data is automatically stored in non-volatile memory. If you don’t want to use the calibration data from the most recent
self-calibration, click the Restore factory cal button. This loads the original calibration data shipped with the instrument.
Diagnostics
This section contains information designed to help troubleshoot the AWG5200 series instruments to the module level. Component-level
repair is not supported.
Use the instrument diagnostics to help troubleshoot these instruments.
Note: The diagnostics are available during normal start-up of the AWG5200 Series application.
Back up data
Before running any diagnostics or calibrations on a unit, copy C:\ProgramData\Tektronix\AWG\AWG5200\Logs to a
another location.
Review this data with an XML editor or Excel spreadsheet to locate the errors. Then when you run diagnostics or calibrations, you can
compare current and previous instrument behavior.
Saving the persistence file
Before you start troubleshooting, use Microsoft Windows Explorer to back up the persistence file to a safe
service copy location. After service is complete, restore the persistence file. The persistence file location is
C:\ProgramData\Tektronix\AWG\AWG5200\persist.xml.
resultStatistics log file
The resultStatistics log file is a good starting point when diagnosing a reported problem. This file contains the instrument’s identification
data and includes which tests were run and results.
This is an .xml file and the best way to view the file is as follows:
1. Open a blank Excel spreadsheet.
2. Click on the Data tab.
3. Click Get Data and then select File > From XML.
4. Navigate to C:\ProgramData\Tektronix\AWG\AWG5200\resultStatistics.xml and import the data.
Diagnostics overview
The instrument runs some self-tests at start-up. These are the POST tests.
The POST tests check connectivity between the boards and also check that the power is within the required range, and that the clocks are
functional. You can also choose to run the POST tests at any time, by selecting POST Only in the Diagnostics window.
If there is an error, the instrument automatically goes into diagnostics.
The levels of diagnostics in the tree are:

• Board level (such as System)
• Area to be tested (such as System Board)
• Feature to be tested (such as Communications)
• Actual tests
Using the Log directory
You can use Microsoft Windows Explorer to copy the log files from: C:\ProgramData\Tektronix\AWG\AWG5200\Logs to
a safe service copy location. This can be done without the application running.
This directory contains XML files, which show statistics about the instrument diagnostics that have been run. Files that you want to look at
are those starting with result, such as resultHistory (raw data from the log at the bottom of the screen when you are running diagnostics)
and calResultHistory (raw data from the log at the bottom of the screen when you are running calibration), and calResultStatistics.
Copy the diagnostic logs from the AWG onto your computer, where you can use an XML editor to view the logs. To import the logs into an
Excel spreadsheet, use the import commands in Excel, for example: Data->From Other Sources ->From XML Data Import (choose file to
open with *Statistics in name).
Files and utilities
System. When you select the About my AWG button under Utilities, the first screen shows information such as the installed options,
instrument serial number, software version, and PLD versions.
Preferences. Check to be sure that the problem is not caused by something being disabled, such as the display, security (USB), or error
messages. The error messages appear in the lower left part of the screen, so if they do not appear, they might be disabled. Status also
appears in the lower left of the screen.
Diagnostics & Calibration window
When you select the Utilities> Diag & Cal>Diagnostics & Calibration, you open a window where you can run the Self Calibration or
Diagnostics. The screen shows the last time that calibration ran and the internal temperature of the instrument when calibration ran. If the
temperature is out of range, a message alerts you to rerun the self calibration. For information on the self calibration, see the section on
Calibration. This is not the same as a full factory calibration.
Error log
When you select Diagnostics, you can select one or more diagnostics groups to run, then select Start to run. When the tests are complete,
the log will appear in the bottom part of the screen.
You can set the log to show All results or Failures only. If All results is selected, a log file will always be generated. If Failures only is
selected, a log file will only be generated if a selected test fails.
Checking Show Failure Info provides more information about the failed test.
Optimum settings for troubleshooting is to select Failures only and check Show failure details.
Note:
Click Copy text to make a text file of the log, which you can copy into a Word file or spreadsheet. The error log tells when the instrument
passed a test, when it failed, and other pertinent failure data. This does not copy the contents of the log file. Access the log files and read
their contents. (See Using the Log directory on page 17)
When you close the Diagnostics window, the instrument goes to the previous state, after running a brief hardware initialization. The
previous state is restored, with the exception that waveforms and sequences are not stored in memory; they will have to be reloaded.
Repackaging instructions
Use the following instructions to prepare your instrument for shipment to a Tektronix, Inc., Service Center:
AWG5200 Series Arbitrary Waveform Generators Service Manual 17
Page 18
Maintenance
1. Attach a tag to the instrument showing: the owner, complete address and phone number of someone at your firm who can be
contacted, the instrument serial number, and a description of the required service.
2. Package the instrument in the original packaging materials. If the original packaging materials are not available, follow these directions:
a. Obtain a carton of corrugated cardboard, having inside dimensions six or more inches greater than the dimensions of the
instrument. Use a shipping carton that has a test strength of at least 50 pounds (23 kg).
b. Surround the module with a protective (anti-static) bag.
c. Pack dunnage or urethane foam between the instrument and the carton. If you are using Styrofoam kernels, overfill the box and
compress the kernels by closing the lid. There should be three inches of tightly packed cushioning on all side of the instrument.
3. Seal the carton with shipping tape, industrial stapler, or both.
