Safety Considerations
Check Signal Generator Functionality
Use the following procedure to confirm that the signal generator powers up and 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.
2. Run the signal generator 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 E8257D/67D, E8663D PSG Service Guide to troubleshoot any failures
detected by the test.
3. Check to see if the ERR annunciator is on.
—If the ERR annunciator is on, review the error messages in the error queue by pressing
Utility > Error Info. The first page of error messages 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 functionality check has passed.
Before you disassemble the instrument, turn the power switch off and unplug the
signal generator. Failure to unplug the signal generator can result in personal
injury.
Electrostatic discharge (ESD) can damage or destroy electronic components. All
work on electronic assemblies should be performed at a static-safe workstation.
When the signal generator is 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.
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.
