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.
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
