Power Output 1 2. 3 Set the power supply voltage to 13.8V dc. and monitor the voltage during transmit. Switch data radio TX and check and record the output power, The nominal output power is adjustable between 1 and SW depending on the programming . Set the PTT switch to OFF . Peak Deviation 1 2. Connect the oscilloscope to the output of the modulation meter.
The section includes voltage which should assist the engineer to isolate and repair the fault. Voltage measurements should be made using a high-impedance voltmeter and the values given are with respect to ground. Careful alignment, using suitable test equipment, and quality interface cables should ensure that the radio meet their specified performance.
