SLR 5000 Series Performance Check
or Testing
9.1
General
The SLR 5000 Series 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.
9.2
Transmitter Testing
CAUTION: The SLR 5000 Series Repeater needs to be taken out of service in order to carry
out performance testing procedures. Unless the repeater is already out of service, it is
recommended to perform the procedures during off-peak hours in order to minimize disruption
of service to the system subscribers.
9.2.1
Introduction
While most module faults can be detected by running the repeater diagnostics, the following procedure
provides a more traditional method of troubleshooting the transmitter circuitry.
This procedure allows the service technician to make minor adjustments and verify proper operation of
the SLR 5000 Series Repeater's transmit circuitry, including:
• Exciter Section of Modem Module
• Power Amplifier Module
• Power Supply Module
In general, the transmitter 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 listed modules and circuitry.
9.2.2
Test Equipment
The following test equipment are required to perform the procedure:
• Aeroflex 3920 Digital Radio Test Set (or equivalent)
• Microphone (GMMN4063_)
• Power Meter and Sensor
• Station Rear Accessory Test Cable
