A method and apparatus for visually characterizing modulated carrier signals, particularly digitally modulated microwave signals, which may be subjected to multipath fading distortion. The method involves sampling the amplitude dispersion of the received signal during a test period, counting the number of times the sampled values fall within each of a number of value ranges and displaying the count per range against range so that counts corresponding to positive and negative amplitude dispersion values are shown in a symmetrical fashion. The shape of the resultant display provides a useful characterization of the signal.
