Chapter 3 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.
3.2 Setup
Supply voltage is provided using a 3.7 VDC power supply. The equipment required for alignment
procedures is connected as shown in the Radio Tuning Equipment Setup Diagram, Figure 4-4.
The initial equipment control settings is shown in Table 3-1. The remaining tables in this chapter
contain the following related technical data:
Do NOT use any form of connector, e.g. wires, crocodile
clips, and probes, to supply voltage to the radio, other
than the Motorola approved battery eliminator.
