CHECKOUT Before starting the operation verification tests in this chapter, perform
an initial checkout of the 681XXC to be tested. This initial checkout
consists of applying power to the signal generator, verifying that it
passes self-test, and resetting it to the factory default parameters.
Power Up First, verify that the rear panel line voltage selector
is set for the correct line voltage, then connect the
681XXC to the power source. This automatically
places the signal generator in operation (front panel
OPERATE LED on).
During power up, the signal generator loads its op-
erating program then returns to the exact setup it
was in when last turned off.
Self Test Next, perform a self-test of the 681XXC to insure
proper operation of the instrument PCBs and other
internal assemblies.
To self-test the signal generator, press SYSTEM ,
then, press Selftest . When the self-test is complete,
the instrument displays the main CW menu.
NOTE
Error conditions detected during self-test
are displayed as error messages on the
data display. They should be corrected be-
fore continuing. Refer to Chapter 6 for a
listing of error messages and descriptions.
Resetting the
681XXC The signal generator should be reset to the factory-
selected default parameters before commencing op-
eration verification testing.
To reset the 681XXC, first press SYSTEM , then
press Reset . The signal generator resets to the CW
frequency mode and displays the CW Menu.
Warmup Time When the signal generator is turned on, allow one
hour of warmup time before performing operational
verification testing. This will assure stable opera-
tion of the instrument.
