Finally, the transmitter’s frequency synthesizer is programmed with
the specified customer’s frequency. A test is performed to verify a
successful lock of the synthesizer circuits.
◆
If the synthesizer lock test passes the transmitter starts normal
operation.
◆
If the synthesizer lock test fails, all of the LEDs on the
transmitter are flashed. The test is repeated and continues in a
loop as long as the test fails and power is applied to the
transmitter.
A ROM test is executed continuously during normal operation. If an
error is detected the transmitter resets itself.
