視装置。In a radio receiver equipped with an antenna tuning circuit, a local oscillation tuning circuit, a mixer, and a demodulation circuit, there is a sweep oscillator that inputs a sweep signal to the antenna input terminal, a detection circuit that extracts the tuning signal of the antenna tuning circuit, and a detection circuit that reads the frequency. Direct tracking viewing of a radio receiver, characterized in that it is equipped with a marker oscillator for tracking, and a measuring circuit that displays the output of the demodulation circuit and the output of the antenna tuning circuit on the same screen, thereby making it possible to directly view the tracking state. Device.
