Использование: прецизионные измерения фазовых сдвигов между двумя гармоническими сигналами. Цель: увеличение точности измерения. Сущность изобретения: устройство построено на основе способа, в соответствии с которым измеряют два мгновенных значения одного из сигналов Ux (t) в моменты времени t1, когда опорный сигнал достигает своего экстремума, и в момент времени t0 1, когда опорный сигнал равен нулю, а значение сдвига фаз F0 определяют при помощи тригонометрического соотношения F0 = arstg [Ux (t0 1) / Ux (t1)] с использованием знака разности фаз исследуемых сигналов. Устройство содержит два блока выборки-хранения, формирователь управляющих импульсов, блок определения знака разности фаз, тригонометрический преобразователь, управляемый блок регистрации. Положительный эффект: устройство позволяет проводить измерения с высокой точностью даже тогда, когда исследуемые сигналы имеют инфранизкую частоту и могут изменяться в широком динамическом диапазоне.Usage: precision measurements of phase shifts between two harmonic signals. Goal: increase measurement accuracy. The inventive device is built on the basis of the method according to which two instantaneous values of one of the signals U x (t) are measured at times t 1 when the reference signal reaches its extremum and at time t 0 1 when the reference signal is zero, and the phase shift value F 0 is determined using the trigonometric relation F 0 = arstg [U x (t 0 1 ) / U x (t 1 )] using the sign of the phase difference of the signals under study. The device contains two sampling-storage units, a shaper of control pulses, a unit for determining the sign of phase difference, a trigonometric converter, a controlled registration unit. Positive effect: the device allows measurements with high accuracy even when the signals under study have an infra-low frequency and can vary over a wide dynamic range.
