A system for verifying the operational performance of command tone generators, transmitters, and antennas including its signal quality and strength as well as its reflected power is disclosed. The system includes a receiver that receives a RF signal and develops an output AM demodulated signal having a d.c. component that is proportional to the amplitude of the received RF signal. The d.c. component serves as an AGC input for the receiver so as to hold the AM demodulated signal constant within a specified range for the input RF signal. The AGC value is digitized to form tuned RF power in sync with the address detection with a microprocessor correcting for AGC nonlinearities.
