Abstract
Multiple signals are graphically presented. A signal for each measured frequency channel is separately represented on a display. Representations of the signals are superimposed. Center channel frequencies for all the representations of the signals are aligned relative to a single position on a first axis. Amplitude for all the representations of the signals is indicated relative to a second axis. Overlap of a signal within a compliance mask indicates violation of an amplitude minimum, an amplitude maximum or frequency drift.
