RF RECEIVE OPERATION
Receiving
The CO M- 120C r eceives CW and modulated signals r anging fr om 250 kHz to 1000 MHz.
In addition to single fr equency oper ation, the CO M- 120C demodulates and detects AM,
FM and PM modulated signals and executes defined fr equency sweep oper ations by
scanning a r ange of pr edeter mined Fr equency List settings.
The CO M- 120C r eceives " off- the- air " signals via the Antenna Connector or connects
dir ectly to the Unit Under Test via the T/R Connector .
Meters
Receive O per ation Meter ing functions include RF Power , AM Modulation, FM Deviation,
Phase Modulation, Distor tion, Fr equency Er r or , AF Fr equency, Received Level and
SINAD.
Full O scilloscope and Spectr um Analyzer oper ation is available.
Testing
Testing in RF Receive O per ation includes measur ing Car r ier Power , Modulation,
Distor tion, SINAD and RF Fr equency Er r or .
