8 Troubleshooting the ParBERT Installation Problems with Clockgroups
8-4 Agilent 81250 ParBERT Installation Guide, May 2004
Problem:
After adding modules or front-ends, the system can no longer run
synchronized tests.
Solution:
After changing any hardware in the system, it is absolutely necessary that
you deskew the system.
This consists of adjusting the instrument connectors and compensating
for internal and external delays. See
How to Adjust the Instrument
Connectors and How to Compensate for Internal and External Delays in
the Agilent 81250 ParBERT System User Guide or in the online Help.
Problems with Clockgroups
Check the following if you have problems setting up clockgroups:
Problem:
For a multi-mainframe configuration, the software does not recognize the
master clockgroup.
Solution:
Have you rebuilt the systems?
When you change the configuration of the clock modules (for example,
when you set up one master clock module and one or two slave clock
modules), you have to reconfigure the systems in the software. See
“How
to Configure I/O Interfaces and Systems” on page 5-9 for instructions.
Solution:
Are all the slave clock modules correctly connected to the master clock
module?
No synchronized tests
Master clockgroup not found
