Safety Considerations
WARNING Before you disassemble the signal generator, turn the power switch off
and unplug the power cord. Failure to unplug the signal generator can
result in personal injury.
CAUTION Electrostatic discharge (ESD) can damage or destroy electronic components. All
work on electronic assemblies should be performed at a static-safe workstation.

Check Signal Generator Operation
Use the following procedure to confirm that the signal generator powers up and that the internal check
identifies no errors.The internal check evaluates theoperation of the signal generator and returns an error
message if it detects a problem.
1. Turn on the signal generator and let it warm up for at least five minutes.
NOTE When signal generators with Option 1E5 are first turned on, the reference oven will be cold
and an error message ERROR 514, Reference Oven Cold appears on the front-panel
display. In addition, both the OVEN COLD annunciator and the ERR annunciator appear on the
front-panel display.
After approximately five minutes, the OVEN COLD annunciator automatically clears, but the
ERR annunciator remains on until all errors are cleared from the error queue.
2. Run the signal generator self test. Press Utility > Instrument Info/Help Mode > Self Test > Run Complete Self
Test. A summary of the test results is displayed after completion of the self test. Refer to the service
guide to troubleshoot any failures detected by the test.
NOTE Some circuits may require up to 50 minutes to warm up before passing the self-test. If
self-tests continue to fail after 50 minutes of warm up, troubleshoot the signal generator.
3. Check to see if the ERR annunciator is on.
• If the ERR annunciator is on, review the error messages in the error queue. Press
Utility > Error Info. The first error message in the error queue appears in the display text area. (Refer
to the signal generator error messages document for information about each error message.)
After resolving all problems causing errors, press Clear Error Queue(s).
•IftheERR annunciator is off, the signal generator self-tests passed.
Install New Firmware
NOTE Firmware version ≥ C.04.54 must be downloaded before installing the new A7 Digital Bus
Baseband Generator board.
1. Use the installation note provided in the ESG firmware upgrade kit, E4400-60597, to install the new
firmware.
2. Perform the verification procedure described in the firmware upgrade installation note.

7
Initialize the Signal Generator Memory
If you have access to a LAN
1. Connect the signal generator to the LAN, using the instructions in the ESG Vector Programming Guide.
2. Press: Utility > GPIB/ RS-232/ LAN > LAN Setup.
3. Write down the IP address shown.
4. Use the web browser on your PC and enter the following URL:
http://<ip-address>/update
where <ip-address> is your signal generator’s IP address obtained in step 2.
5. Click “Initialize Option 601 and 602”.
NOTE To undo the previous steps, press “Restore Factory Setup”
If you do not have access to a LAN
1. Use a PC or UNIX workstation with GPIB or RS-232 IO capabilities.
2. Use the PC or UNIX workstation and send the following command to the signal generator:
:DIAG:MFG “UPDATE_FIXED_SETUP_P7”.
3. Verify that no error messages appear on the signal generator’s front-panel display.
4. If an error appears, press: Utility > Error Info > Clear Error Queue and repeat step 2.
NOTE To undo the previous steps, send the command :DIAG:MFG “RESTORE_FIXED_SETUP”.
