Abstract : A DICASS test set utilizes a microcomputer to process information from an input and a down link section, generate the appropriate control logic for all the various electronic sections and format the appropriate output data for the output in uplink sections. A keyboard is provided from which an operator can input data the controller. A display and printer is provided to which the controller outputs informations to the operator. The downlink section consists of a UHF receiver, envelope detector, timer, filter bank, decoder, frequency counter. The uplink section consists of a reverberation simulator, a signal synthesizer, bearing, echo level and sea state controllers, three separate noise sources, multipliers and summing circuitry.
