Abstract

Изобретение относитс  к технике измерений на СЕЧ н может использоватьс  при измерении больших ослаблений . Цель изобретени  - повышение точности. На вход исследуемого СВЧустройства (аттенюатора 3) подаетс  импульсно-модулированный сигнал генератора 1 , который промодулирован фазовым модул тором 2. Выходной сигнал аттенюатора 3 при помощи гетеродина 5 и смесител  4 преобразуетс  в сигнал промежуточной частоты. Этот сигнал сравниваетс  с опорным сигналом в измерителе 6 отношений. Точность повьшаетс  за счет осуществлени  фазовой модул ции по линейному закону с частотой Q ,где t часто .та импульсной модул ции, Q скважность , h- целое число. Таким образом исключаетс  вли ние недоста- е точности уровн  экранировани  измерн-® (Л тельного устройства на погрешность измерени  ослаблени . 1 ил.This invention relates to measurement techniques for SECH and may be used in measuring large attenuations. The purpose of the invention is to improve accuracy. The input of the microwave device under study (attenuator 3) is supplied with a pulse-modulated signal of generator 1, which is modulated by phase modulator 2. The output signal of attenuator 3 is converted into intermediate frequency signal by means of local oscillator 5 and mixer 4. This signal is compared with the reference signal in the 6 ratio meter. Accuracy is increased due to the implementation of phase modulation according to a linear law with a frequency Q, where t is often. That of pulse modulation, Q is the duty cycle, h is an integer. In this way, the influence of the lack of accuracy of the shielding level of the measuring-® (of the mobile device) on the measurement error of attenuation is eliminated. 1 Il.
