An automatic test set for FM/FM telemetry systems

Techniques of automation are applied to the problem of preflight check-out of airborne telemetry systems. The result is a test set that measures and analyzes key system parameters without operator participation. Operation of the subcarrier analyzer portion of the test set is described. Circuit details of pre-set binary counter chain, counter readout matrix, and GO/NO-GO voltmeter are given. An example of typical test set packaging is shown.
