TB8100 Service Manual Reciter Fault Finding 95
© Tait Electronics Limited September 2006
3.11 Final Tasks
Once you have completed the testing and repair (if required) of the reciter,
carry out the following tasks.
Task 1 —
Final Tests
Test the reciter to confirm that it is fully functional again. The
recommended tests are listed below:
1. Reprogram the customer’s configuration into the reciter, and
re-enable the customer’s feature sets (if necessary).
2. Select a correctly configured channel.
3. Check that no alarms are generated.
4. Check that the DC supply current is correct (refer to Table 3.1 on
page 76).
5. Inject an RF test signal (1kHz audio, 60% modulation) of the
required frequency at –80dBm (22.4µV). Check that the
performance of the receiver meets the specifications in Table 3.2 on
page 96.
6. Key the exciter and check that the performance meets the
specifications in Table 3.3 on page 97.
7. Inspect the reciter to make sure that nothing has been damaged
during any test or repair procedures. Make sure all screws securing
the cover to the heatsink are in place and tightened to the correct
torque.
It is good practice to record the test results on a separate test sheet. You can
then supply a copy of the test sheet to the customer as confirmation of the
repair.
Task 2 —
Final
Administration
The final administration tasks are the standard workshop procedures for
updating the fault database and returning the repaired reciter to the
customer with confirmation of the repair.
If the reciter could not be repaired for one of the following reasons:
■ fault not located
■ repair of fault failed
Level-1 service centres should return the faulty reciter to the nearest
Accredited Service Centre, and level-2 service centres should return the
reciter to the International Service Centre. Supply details of the customer,
the fault and, if applicable, the attempted repair.
