Instruments based on the radio. Determination of the frequency of an unmodulated source, an external signal. With the help of measuring GS you can configure any radio transmitting and radio-emitting devices in the frequency range 150 — 12 000 kHz, in the CW mode, and the mode AM or IM. In the absence of signal modulation of an external RF source (CW mode), its frequency can be determined by the method of zero beating with the frequency of HS. The block diagram implementation of the method of zero beat is illustrated.
