INTRODUCTION
1-3 RF RECEIVE OPERATION
Receiving
The COM-120C receives CW and modulated signals ranging from 250 kHz to 1000 MHz.
In addition to single frequency operation, the COM-120C demodulates and detects AM,
FM and PM modulated signals and executes defined frequency sweep operations by
scanning a range of predetermined Frequency List settings.
The COM-120C receives “off-the-air” signals via the Antenna Connector or connects
directly to the Unit Under Test via the T/R Connector.
Meters
Receive Operation Metering functions include RF Power, AM Modulation, FM Deviation,
Phase Modulation, Distortion, Frequency Error, AF Frequency, Received Level and
SINAD.
Full Oscilloscope and Spectrum Analyzer operation is available.
Testing
Testing in RF Receive Operation includes measuring Carrier Power, Modulation,
Distortion, SINAD and RF Frequency Error.
Use the independent Audio/Data/Signaling Generators to
modulate the Unit Under Test when performing RF Receive
Operation.
