Description

Изобретение имеет целью повысить точлюсть измерени  угла сдвига по фазе между двум  переменными синусоидальными напр жени ми . Измерение основано на уравнивании фазового сдвига межд}- напр жени ми путем изменени  фазы одного из них с помощью градуированного фазовращател , по щкале которого отсчитываетс  сдвиг фаз.The invention aims to increase the accuracy of measurement of the phase angle between two variable sinusoidal voltages. The measurement is based on equalizing the phase shift between the} voltages by changing the phase of one of them using a graduated phase shifter, at the tip of which the phase shift is counted.

Поставленна  задача решаетс  путем иодачи сравниваемых напр жений на реактивные элементы контуров двух частотно-модулированных генераторов различной частоты, напр жени  которых поступают на смеситель.

Исходное напр жение L, (sin Щ подаетс  на вход Bxi устройства . После уснлени  в усилителе УС, это напр жение через реактивный элемент РЭ воздействует на частоту высокочастотного генератора ГьThe initial voltage L, (sin U is fed to the input Bxi of the device. After being ushered in the amplifier of the US, this voltage across the reactive element of the electronic circuit affects the frequency of the high-frequency generator

Напр жение U sinXf-f ), фаза которого относительно напр жени  f/i должна быть измерена, подаетс  на вход Вх. Это напр жение поступает на широкополосный фазовращатель ФВ, усиливаетс  усилителем УС и через реактивный элемент Pdz воздействует на частоту генератора Га. Напр жени  генераторов Г и Гз поступают на смеситель СМ и разностна  частота выдел етс  на фильтре Ф. ИнтенсивThe voltage U sinXf-f), the phase of which relative to the voltage f / i should be measured, is fed to the input Bx. This voltage is applied to the wideband PhW phase shifter, amplified by the US amplifier, and through the reactive element Pdz affects the frequency of the generator Ha. The voltage of the generators G and Gz is fed to the mixer SM and the difference frequency is allocated on the filter F. Intensive
