Troubleshooting the Analyzer
To perform self tests
c
Determine the probable faulty assembly and next test by
comparing the functional test results to the following table.
If the analyzer's test log matches more than one entry in the table,
use the entry closest to the beginning of the table. Assemblies are
listed in order of probable failure when more than one assembly
can cause the failure.
The table lists the probable faulty assembly or assemblies and
troubleshooting procedure to do before replacing an assembly.
The messages in the table include only the parts of the failure
messages that point to the assemblies failing. For example, many
of the failure messages give the channel number ( 1 or 2 ),
amplitude (mkr y: amplitude), and frequency (mkr x: frequency)
of the failure.
