Receiver Testing
CAUTION:
Performing this procedure requires that the repeater be taken out of service. It is recommended
that, unless the SLR 1000 Series Repeater is already out of service, this procedure be
performed during 
off-peak hours so as to minimize the disruption of service to the system subscribers.
If the repeater operates as a repeater, the transmit output from the repeater must be connected
to a dummy load to prevent over-the-air broadcast during Receiver testing.
7.3.1
Introduction
While most module faults can be detected by running the SLR 1000 Series Repeater diagnostics, the
following procedure provides a more traditional method of troubleshooting the Receiver circuitry.
This procedure allows the service technician to make minor adjustments and verify proper operation of
the receiver circuitry on the Transceiver Board.
In general, the Receiver circuitry is exercised by injecting and measuring signals using a Service
Monitor (or equivalent). Incorrect measurement values indicate a faulty module(s); measurement
values within the acceptable range verify proper operation of the receiver circuitry on the Transceiver
Board.
