Performance Check or Testing General Description
The SLR 1000 Repeater meets published specifications through the manufacturing process by utilizing
high-accuracy laboratory-quality test equipment. The recommended field service equipment
approaches the accuracy of the manufacturing equipment with few exceptions. This accuracy must be
maintained in compliance with the equipment manufacturer’s recommended calibration schedule.
NOTICE: Although these repeaters function in digital and analog modes, all testing is done in
analog mode. Digital Repeater tests can be performed using an Aeroflex 3900 Series Service
Monitor, if the DMR Digital Repeater Test Option is purchased. This auto testing could be
performed in lieu of the following Manual testing.

Transmitter Testing
Incorrect measurement signaling values of the SLR 1000 Repeater indicate a faulty module. Testing
the transmitter circuitry is done by injecting and measuring signals using a Service Monitor (or
equivalent). Measurement values within the acceptable range verify proper operation of the transceiver
board and circuitry.
CAUTION: The SLR 1000 Repeater must be taken out of service to carry out performance
testing procedures. Unless the repeater is already out of service, perform the procedures during
off-peak hours to minimize disruption of service to the system subscribers.
While most module faults can be detected by running the repeater diagnostics, Verifying Transmitter
Circuitry
on page 66 provides a more traditional method of troubleshooting the transmitter circuitry
and allows the service technician to make minor adjustments and verify proper operation of the
repeater transmit circuitry.
