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 the operation 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)
.
• If the
ERR
annunciator is off, the signal generator self-tests passed.
