FIELD: training devices for radio engineering, possible use for visual demonstration of modes of serial searching of impulse signals at a frequency, principles for creating additional receipt channels in panoramic receiver and methods and devices for suppressing them.
SUBSTANCE: the device allows demonstration of three modes: in first mode, processes of signal search frequency-wise by panoramic receiver are demonstrated, in second mode - presence of additional receipt channels in panoramic receiver, in third one - methods and devices for using additional receipt channels.
EFFECT: expanded range of frequency searching without extension of heterodyne frequency adjustment range due to usage of additional receipt channels in panoramic receiver.
