Run the Service
Program
The best approach to repair the HP 85106D at this point is to verify that the
HP 85101 display/processor is working properly. When its operation is
verified it can be used as your diagnostic controller.
From the HP 85106D mm-wave system disconnect any external controller,
printer, plotter, disk drive, or other equipment and all their cables. Leave
only the instruments listed below attached to the system:
•
HP 8510C network analyzer
•
HP 85104A mm-wave test sets
•
HP 85105A mm-wave controller
•

This group of internal diagnostics, called the Service Program, gives the
fastest and most complete check of the HP 85106D system. Whenever your
HP 85106D system appears to have a failure you can use this program to
check the boards in the HP 8510C and HP 85105A.
In general, the Service Program is used for the following purposes:
•
When there is a self-test failure, run the Service Program diagnostics for
the board assembly that failed. Verify the failure.
•
When there is a running error message (caution type), run the "Service
Program" diagnostics for those board assemblies indicated in the
"Running Error Messages" section in the HP 8510C Service Manual.
The service program verifies whether the board has a detectable
problem.
•
When there is any reason to suspect a board-level problem, run the
"Service Program" diagnostics.
•
After a board assembly is replaced, run the appropriate service program
diagnostics again to verify that the board-level failure is repaired.
