Transceiver Performance Testing
3.1 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.
3.2 Setup
Supply voltage is provided using a 13.2Vdc power supply. The equipment required for alignment
procedures is connected as shown in the Radio Tuning Test Equipment Setup Diagram, Figure 4-4,
on page 4-3.
