RT-9000 B
Procedure - Systems using a Non-Resonant Antenna
From the BITE Sub-Menu shown in Figure 7.3.3.2, depress the ‘TX – BITE’ key at
2 . The RT-9000 B will
start executing the Transmit BITE test routine.
The Antenna Coupler will begin a “Tuning Cycle” using the first test frequency. While the Antenna Coupler
tuning cycle is in progress, a ‘COUPLER TUNING’ message will appear in the Operational Display. After the
Antenna Coupler finishes tuning (or the maximum allotted tuning time expires), a test result message will be
displayed. A ‘SYSTEM READY’ or ‘SYSTEM FAULT’ message will be displayed. If the Antenna Coupler is
totally inoperative, a ‘COUPLER FAULT’ message will instead be displayed. In both above cases, the
Transmit BITE test routine will not stop if either of these Faults is found.
After the first test frequency tuning cycle is finished, the test routine will then step to the second test
frequency and repeat this process. This sequence will repeat until all eight (8) test frequencies have been
tuned by the Antenna Coupler. These individual tests together form the Antenna Coupler tuning test section.
Test frequencies that result in ‘SYSTEM FAULT’ test outcome will be excluded from the ‘Filter Module’ tests
later in the Transmit BITE test routine. When these “No Tune” condition(s) are found, the findings will be
displayed after the Transmit BITE test routine completely finishes.
After the Antenna Coupler tuning tests are completed, test result messages will begin appearing as the next
four (4) Transmitter Modules are tested.
The Transmit BITE test routine concludes by testing the Filter Module. Of the eight (8) possible frequencies,
only those that successfully tuned and resulted in ‘SYSTEM READY’ message will be used. During this test,
the RT-9000 B will key and unkey the Transmitter as it steps through these test frequencies.
As the Transmit BITE test runs, it will stop on the first Transmitter Module Fault found. This Fault must be
corrected before proceeding. If additional Faults are present, the Transmit BITE test routine must be repeated
until no further Faults are found.
Refer to the following chart for Transmit BITE test routine details.
