Abstract :
The application of a double-frequency test technology and automated system using two frequency-sweeping test signals for detection, identification, and parameter measurement of all linear and nonlinear interference responses (spurious, intermodulation, etc.) of radio receivers is described. An experimental analysis of receiver susceptibility to out-of-band interference at its antenna input, including the measurement of high-order intermodulation, is presented. Opportunities and advantages of using the double-frequency test technology for detection of nonlinear noise and spurious generation areas in receivers are discussed. A new technique for identification (recognition) of the receiver responses to interference is proposed.
