Performance test failure troubleshooting
This section describes the adjustment and troubleshooting procedures used when the
E5061A/E5062A fails the performance tests. If the performance of the instrument is
critical for the test limits and seems to be adjustable, perform first the adjustment(s) related
to the failed test. When the test result is far from the tolerance of the test or the
performance is not adjustable, isolate the faulty assembly in accordance with the
"Performance tests failure troubleshooting procedure".

Recommended adjustment for performance test failure

Table 4-5 shows the recommended adjustments when the performance test fails. Select the
adjustment program corresponding to the recommended adjustment and perform the
adjustment.

Table 4-6 represents the relationships between the failed test and probable faulty assembly.
If the performance test failure cannot be removed by a proper adjustment, replace the
assembly shown in this table.
Note that this table lists some typical cases. There are possibilities that other assembly may
be faulty. To troubleshoot further, perform the diagnostic test procedures.
NOTE When Crosstalk, System dynamic range or Uncorrected system performance test fails,
check first whether the connections of the RF semi-rigid cables between the suspicious
assembly and others are tight or loose. Also check for possible disconnection (impairment)
