Safety Considerations

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.

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 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.

When the signal generator is first connected to ac line power, the error
message
the

ERROR 514, Reference Oven Cold occurs, which causes both

OVEN COLD annunciator and the ERR annunciator to turn on.

After approximately five minutes, the
automatically clears, but the
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 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, E8251-90359, to troubleshoot any failures
detected by the test.

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.

— 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).

ERR annunciator remains on until all errors

OVEN COLD annunciator

— If the ERR annunciator is off, the signal generator functionality check has passed.
