Performance test failure troubleshooting
Table 4-11 and Table 4-12 represent 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 diagnostics test
procedures.

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) of the cables
and connectors.
