CHECKOUT
Before starting the operation verification tests in this chapter, perform
an initial checkout of the 680XXB to be tested. This initial checkout
consists of applying power to the CW 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
680XXB to the power source. This automatically
places the CW generator in operation (front panel
OPERATE
LED on).
During power up, the CW generator loads its operat-
ing program then returns to the exact setup it was
in when last turned off.
Self Test
Next, perform a self-test of the 680XXB to insure
proper operation of the instrument PCBs and other
internal assemblies.
To self-test the CW generator, press
SYSTEM
.
Then, press the System Menu soft-key
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 before con-
tinuing. Refer to Chapter 6 for a listing of
error messages and descriptions.
Resetting the
680XXB
The CW generator should be reset to the factory-se-
lected default parameters before commencing opera-
tion verification testing.
To reset the 680XXB, first press
SYSTEM
, then
press
Reset
. The CW generator resets to the CW
frequency mode and displays the CW Menu.
Warmup
Time
When the CW generator is turned on, allow one hour
of warmup time before performing operational verifi-
cation testing. This will assure stable operation of
the instrument.
