Communication transmitter-receiver is one of the important airborne electronics equipments. The sensitivity of receiver is an important test content which reflects the performance of the receiver. It takes long time by traditional manual measurement, moreover, the precision is low and the error is big. A fast method of testing sensitivity is introduced by utilizing FFT on the basis of airborne communication equipment auto test system (ATS). An engineering application shows that the test efficiency and precision are improved compared with traditional manual measurement method.
