Troubleshooting
This chapter helps qualified service personnel troubleshoot
the logic analysis system to find defective assemblies. The
troubleshooting consists of flowcharts, self- test instructions,
and tests. This information is not intended for
component- level repair.
If you suspect a problem, start at the top of the first
flowchart. During the troubleshooting instructions, the
flowcharts will direct you to perform other tests. The other
tests are located in this chapter after the flowcharts.
The service strategy for this instrument is the replacement
of defective assemblies. This instrument can be returned to
Agilent Technologies for all service work, including
troubleshooting. Contact your nearest Agilent Technologies
Sales Office for more details.

within the same flowchart. A circled alpha references
connections within the flowchart. Start your troubleshooting
