Abstract

FIELD: measurement technology. SUBSTANCE: method involves modulation of electromagnetic radiation signal by low- frequency signal, detection of signal passed through analyzed equipment by radiation detector, signal filtering by narrow-band amplifier, detection by low-frequency detector, and display; signal picked off output of narrow-band amplifier is compared in phase by phase-locked loop circuit with its output signal which is used for modulating electromagnetic radiation signal. EFFECT: enlarged functional capabilities. 1 dwg

Изобретение относится к измерительной технике, а именно к устройствам для измерения коэффициентов передачи различных устройств или материалов в различных участках диапазона частот электромагнитного излучения. В известном способе, включающем модуляцию сигнала электромагнитного излучения сигналом НЧ, детектирование сигнала, прошедшего через исследуемый объект детектором излучения, фильтрацию сигнала узкополосным усилителем, детектирование НЧ детектором и индикацию, сигнал с выхода узкополосного усилителя сравнивается по фазе схемой ФАПЧ с ее выходным сигналом, который используют для модуляции сигнала электромагнитного излучения.The invention relates to measuring equipment, namely, devices for measuring the transmission coefficients of various devices or materials in various parts of the frequency range of electromagnetic radiation. In the known method, which includes modulating the electromagnetic radiation signal with an LF signal, detecting a signal transmitted through an object under study by a radiation detector, filtering a signal with a narrow-band amplifier, detecting an LF detector with an indication, the signal from the output of a narrow-band amplifier is compared in phase with the PLL with its output signal, which is used to modulate the signal of electromagnetic radiation.
