Checking Signal Generator Functionality
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.
NOTE When signal generators with Option 1E5 are first connected to ac line power, the error
message ERROR 514, Reference Oven Cold occurs which causes both the OVEN COLD
annunciator and the ERR annunciator to turn on.
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.
1. Turn on the signal generator and let it warm up for at least five minutes.
2. Run the instrument self-test by pressing Utility > Instrument Info/Help Mode > Self Test > Run Complete Self
Test. Upon completion a summary of the self-test will be displayed. Use 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 instrument.
3. Check to see if the ERR annunciator is on.
•IftheERR annunciator is on, review the error messages in the error queue by pressing
Utility > Error Info >View Next Error Message. 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 functionality check has passed.
