To troubleshoot performance test failures

To troubleshoot performance test failures
Use this test when a performance test is failing and the self tests passed
except for calibration.

Determine if an adjustment is causing the analyzer to fail a
performance test.
a Do the adjustments in chapter 2, ''Adjusting the Analyzer'' for the
following assemblies:
A10 Analog Input
A21 A/D Converter
A35 Analog Source

A60 Frequency Reference

A61 Clock

b
Repeat the failing performance test.
Determine the probable faulty assembly or next test by comparing the
performance test results to the following table.
If more than one performance test fails, use the entry closest to the
beginning of the table. The table lists the assembly or assemblies
most likely to cause the failure. In some cases, the failure can be
isolated to one assembly based on the exact failure. When the cause
of the failure cannot be isolated to one assembly, an additional test is
provided to help isolate the faulty assembly. Multiple probable faulty
assemblies are listed in order of probability.
