Performance Test failure Troubleshooting
Table 2-8 and Table 2-9 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.
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.
