Description
Изобретение относитс к эпектрорадиоизмерени м , может быть использовано в ф зометрах, особенно при измерении сдвига фаз в динамическом диапазоне 0-360 . Известны устройства дл однозначного измерени сдвига фаз синусоидальных напр жений , содержащие управл емый фазовр щатель, фазовый детектор, а также цепь управлени фазовращателем 1, Эти устройства сложны, а использование в них в качестве индикатора осциллографа сказываетс на точности измерени . Однако необходимость Б фазовом манипулировании приводит на высоких частотс-г к погрешност м измерени сдвига фаз. Цель изобретени - повыгленне точносиизмерени в диапазоне BLICOK IX частот достигаетс тем. что устройстно дл;1 ызм;:. рени сдвига фаз, содержащее два фазэв)-детектора , одик из которььч мере, ограничител с легочниками входного и опорного сигналов, другой непосредспч мг. с iiCTOHiiiiKOM входного сигнала - и чс; - ЬЗОБрашатэл:. - с ;:сточи;1ком эиорно- сигнаиТ . а т к:-:чд г:м;; гао Ллчита. lix лThe invention relates to radio measurements, can be used in physiometers, especially when measuring the phase shift in the dynamic range of 0-360. Devices for unambiguous measurement of the phase shift of sinusoidal voltages are known, including a controlled phase shifter, a phase detector, and a control circuit of the phase shifter 1. These devices are complex, and using an oscilloscope as an indicator affects the accuracy of the measurement. However, the need for phase shift manipulation at high frequencies-r leads to measurement errors in the phase shift. The purpose of the invention, in terms of precision measurement in the BLICOK IX frequency range, is achieved by that. what is device for; 1 sys;;. phase shift, containing two phases) of the detector, one of which is the limiter with the input and reference signal lockers, the other directly mg. with iiCTOHiiiiKOM input signal - and hr; - BZBrashatel :. - from;: stoichi; 1kom of Tornión. a t to: -: chd g: m ;; Gao Llchita. lix l
