Description
Устройство содержит генератор 1 тестовых сигналов, подключе1шый к амплитудному модул тору 2, который соединен с высок частотным генератором 3 и с синхронными детекторами 4 и 5, другие входы которых подключены к управл емым фазовращател м 6 и 7, Входы фазовращателей 6 и 7 соединены между собой и подключены к генератор 3, Выходы детекторов 4 и 5 подключены к фильтрам 8 и 9 нижних частот, выходы котррых вл ютс выходами устройства.The device contains 1 test signal generator, connected to amplitude modulator 2, which is connected to a high frequency generator 3 and synchronous detectors 4 and 5, the other inputs of which are connected to controlled phase shifters 6 and 7, the inputs of phase shifters 6 and 7 are interconnected and connected to oscillator 3, the outputs of the detectors 4 and 5 are connected to the low pass filters 8 and 9, the outputs of which are the outputs of the device.
Напр жение высокочастотного генератора 3 модулируетс в амплитудном модулжеторб 2 нащэ жением генератора 1. Модулированное высокочастотное напр жение поо тупает на один из входов детекторов 4 и 5, на другие входы которых поступают сигналы от генератора 3 через фазовращатели 6 и 7. Выходные напр жени детекторов 4 и 5 повтор ют форму напр жени генератора 1, а их амплитуды завис т от величины углов фазовых , сдвигов, зада1ваемых фазовращател ми 6 и 7. Отфильтрованные фильтрами 8 и 9 выходные напр жени детекторов 4 и 5 подаютс на в.ыходы устройства, The voltage of the high-frequency generator 3 is modulated in the amplitude modulator 2 by oscillating the generator 1. The modulated high-frequency voltage enters one of the inputs of the detectors 4 and 5, the other inputs of which receive signals from the generator 3 through phase shifters 6 and 7. The output voltages of the detectors 4 are 4 and 5 repeats the shape of the voltage of the generator 1, and their amplitudes depend on the magnitude of the phase angles, shifts set by phase shifters 6 and 7. The output voltages of the detectors 4 and 5 filtered by the filters 8 and 9 are fed to the outputs -keeping,
Выходное сощ)отивление устройства дл определени фдзоамплитудных, погреишостей фазометров остаетс неизменным в процессе регулировани уровней выходных сигналов. Паразитные фазовые сдвиги, возникающие при регулйровании уроеней. .сиснадев-: -устройствеThe output from the device for determining the fdzo amplitude phase error gages remains unchanged in the process of adjusting the output signal levels. Parasitic phase shifts arising from the regulation of uroeni. .sisnadev-: -device
на частоте высокочаспл-ного сигнала, в пересчете на частоту тестоаогр сишала оказываютс малыми.at the frequency of the high-intensity signal, in terms of the frequency of the testao-sishal, turn out to be small.
