Performance test failure troubleshooting

Table 4-5 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 another assembly
may be faulty.
NOTE When RF IN Port VSWR test fails, check first whether the connections of the RF
semi-rigid cables between the suspicious assembly and others are tight or loose. Also
