Description

Д, устранени  затруднений, возникающих при измерении сдвига фаз в области высоких частот, вместо измерени  сдвига фаз на высокой частоте производ т измерение соответствующего ему сдвига фаз па низкой частоте. При этом точность измерени  получаетс  более высока , чем при других способах.D, eliminating the difficulties arising from measuring the phase shift in the high frequency region, instead of measuring the phase shift at a high frequency, measuring the corresponding phase shift at the low frequency. At the same time, the measurement accuracy is higher than with other methods.

Описываемый способ измерени  сдвига фаз отличаетс  от известр1ого по методу комнепсации тем, что исследуемое напр жение модулируетс  вспомогательной низкой частотой, котора  затем выдел етс  из спектра модулированных частот.The described method of measuring the phase shift differs from the one known by the room clamp method in that the voltage under study is modulated by an auxiliary low frequency, which is then separated from the spectrum of the modulated frequencies.

Сущность способа измере(П1Й заключаетс  в следующем.The essence of the method of measurement (P1I is as follows.

Поступающие от генератора напр жение с частотой /I, на которой хот т измерить сдвиг фаз, и напр жение низкой частоты F от генератора подаютс  на смесите.чь.The voltages coming from the generator with the frequency / I, at which the phase shift is measured, and the voltage of the low frequency F from the generator are fed to the mixer.

Then, the phase shift at a low stable frequency is measured in the usual way.

1. Способ измерени  сдвига фаз, основанный на методе компепсмпии. о т л и ч а 10 П1 и и с   тем, что, с целью устранени  затруднений при измерепин сдвига фаз на высокой частоте, исследуемое напр жение высокой частоты модулируют низкой вспомогательной частотой с последующим отфильтровывапием из спектра частот частоты модул ции, име№ 107566 ющей сдвиг фаз, соответствующий сдвигу фаз напр жени  высокой частоты . 2. Способ по п. 1, отличающ и и с   тем, что, при компенсации несущей частоты в индикаторной цепи примен ют детектор, по величине выходного напр лсени  которогоконтролируют степень компенсации несущей частоты.1. A method for measuring phase shift based on the comppexmpi method. This is the reason why, in order to eliminate difficulties with high-frequency phase shift measurements, the high-frequency voltage under investigation is modulated by a low auxiliary frequency followed by filtering from the frequency spectrum of the modulation frequency, having 107566 phase shift corresponding to the phase shift of the high frequency voltage. 2. The method according to claim 1, which is also distinguished by the fact that, when compensating for the carrier frequency, a detector is used in the indicator circuit, according to the output voltage of which the degree of compensation of the carrier frequency is monitored.
