If a Transmitter Module BITE Fault is found
The following actions will typically occur when a Fault is found:
1. The Transmit BITE (‘TX - BITE’) test routine will halt.
2. A Module Fault message will be displayed at
4 in the Operational Display .
3. The Red ‘FAULT’ lamp on the Front Panel at 5 will be lit.
Proceed to Section V of this manual for fault isolation and repair procedures.
If the Transmit BITE test routine finishes without displaying a Fault message, one of the following messages
will appear in the Operational Display. The following summarizes these messages and their meaning.
•
‘TEST COMPLETED’. This message means all Transmitter Modules passed the Transmit BITE test
routine. It also means that the VSWR test results for all eight (8) test frequencies were within
acceptable limits.
•
‘VSWR HI AT XX XX MHZ’. This message means all Transmitter Modules passed the Transmit BITE
test routine but a high VSWR condition was found on one test frequency. In this case, XX XX
indicates the specific test frequency. The decimal point is not displayed.
•
‘VSWR HI AT MULT MHZ’. This message means all Transmitter Modules passed the Transmit BITE
test routine but a high VSWR condition was found on two (2) or more of the test frequencies.
If either of the preceding VSWR-related messages appears, proceed to Section V of this manual for fault
isolation and repair procedures.
After this test is completed, the User may do the following:
•
Repeat this Transmit BITE test. Depressing the ‘TX-BITE’ key again at 2 as shown in Figure 7.3.3.2
will cause the Transmit BITE test routine to repeat.
•
Repeat the Receive BITE test, as previously covered.
•
Exit BITE mode. Depressing the ‘END’ key at 3 will return to the main menu and resume normal
operation.
