1. An automated system for conducting a plurality of performance tests on a radio receiver for determining the full response characteristics of the receiver, the system being of the type including means for producing a plurality of predetermined simulated broadcast signals, means for introducing the simulated signals into the receiver, said receiver producing an output signal responsive to each one of said simulated broadcast signals, means connected to said receiver for detecting each said output signal, and means connected to said receiver for analyzing the quality of each said output signal, the improvement comprising:

  • a. a plurality of said analyzing means in parallel, each of said analyzing means comprising means for comparing a particular one of each said receiver output signals with respect to a specific set of preset parameters for conducting one of said plurality of performance tests;

    b. means for selecting and activating a specific one of said analyzing means in response to the particular output signal produced by the receiver, andc. one of said simulated broadcast signals including a plurality of separate and distinct components, said receiver being responsive to said broadcast signals to produce an output signal comprising a like plurality of separate and distinct components, said analyzing means including means for comparing the relative strengths of the respective components of the output signal.
