EDUCATIONAL RADIOENGINEERING DEVICE Russian patent published in 2008 - IPC G09B23/18 

FIELD: educational devices.

SUBSTANCE: device allows showing modes of sequent search of pulse signals by frequency, principles of formation of additional receiving channels in panoramic receiver and methods and aids of their suppression. Device has model of radar station, first, second, third and fourth high frequency generators, modulator, first, second and third counters, sweep generator, heterodyne, first and second mixers, first and second intermediate frequency amplifiers, first and second amplitude detectors, video amplifier, electron-ray tube, first and second adders, first, second, third, fourth, fifth and sixth switches, first and second +90° phase shifters, threshold unit, first, second, third and fourth switches, frequency meter, comparison unit and memory unit. Excess information on carrier frequency of continuous signal is shown and repeat measurement and registration of carrier frequency of received continuous signal is excluded.

EFFECT: widened functional abilities.
