HP 8360 - Manual (Page 455)

Description The preliminary check provides assurance that most of the internal
functions of the synthesizer are working. The main check provides a
general check of the overall functions of the synthesizer. No external
equipment is needed.
Preliminary Check Each time the synthesizer is turned on the synthesizer performs a
series of self tests on the internal CPU, power supplies, and front
panel. When the self test is complete, the synthesizer returns to the
same functional configuration that it was in prior to power off. When
the
key is engaged, the synthesizer returns to the factory or
user preset functional configuration.
1. Turn the synthesizer on. Note the functional configuration.
2. Turn the synthesizer off. Verify that the amber STANDBY LED is
on.
3. Turn the synthesizer on. Verify that the amber STANDBY LED is
off, and that the green POWER ON LED is on.
a. Check the display, a cursor will appear in the upper left corner
followed by the HP-IB language, HP-IB address, and the date
code of the firmware installed in the synthesizer.
b. The display will now indicate the functional configuration
noted in step 1.
c. Check the fan, it should be turning.
