TRANSCEIVER PERFORMANCE TESTING

1.0 General

These radios meet published specifications through their 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 manufacturer’s recommended calibration schedule.

2.0 Setup

Supply voltage is provided using a power supply (13.8 Vdc for low power models, 13.6 Vdc for high
