Agilent 85629B Test and Adjustment Module
The test and adjustment module (TAM) can be used with the 8560E/EC,
Agilent 8561E/EC and Agilent 8563E/EC. A powerful feature of the
TAM is the automatic fault isolation routine. If a problem with the
spectrum analyzer is suspected, in most cases automatic fault isolation
can determine whether or not a fault exists in the analyzer. There are
some problems, such as excessive residual FM, that automatic fault
isolation cannot detect. As a minimum, the display and keyboard must
be operational to execute automatic fault isolation.
Running the Automatic Fault Isolation Routine
To start the automatic fault isolation routine, press and
MODULE
DIAGNOSE. Rotate the front-panel knob until the arrow points to
Automatic Fault Isolation. Press . The CAL OUTPUT must be

connected to the INPUT 50Ω. A BNC cable and Type N-to-BNC adapter
is shipped with each analyzer in the front cover. Press CONTINUE, and
the automatic fault isolation routine begins.
The automatic fault isolation routine performs checks of five sections of
the analyzer. Progress of the routine is displayed on the screen. The
routine stops as soon as it detects a failure. If no failures are detected,
the automatic fault isolation routine takes about 90 seconds to
complete.
If a failure is detected, either continue troubleshooting using the
service guide or return the analyzer to the nearest Agilent Technologies
service center as described in "Returning Your Analyzer for Service" in
this chapter. If a GPIB printer is properly connected and configured, a
hard-copy printout of the automatic fault isolation results can be
obtained by pressing . Include a copy of this printout with

the analyzer if it is being returned to an Agilent Technologies service
center for repair.
