  • Patent number: 4388644
    Abstract: A system for monitoring the operation of a multichannel receiver includes a channel monitor coupled to the sync separator of the receiver for collecting and transmitting channel information to a central collector station. The collector station selectively responds to one of a plurality of channel monitors to record, in sequential order, channel information. Each of the channel monitors is similar and includes a synchronizing pulse generator triggered by the vertical synchronizing pulse from a receiver to generate a match recognize pulse when a frequency coupled to the receiver from the monitor and the channel frequency have a preestablished relationship. To generate the match recognize pulse a counter provides signals to a tuning matrix that controls a frequency synthesizer or plurality of oscillators for generating the frequency coupled to the receiver for the match evaluation. Also, the counter activates a data encoder that provides channel information to the collector station.
