Description
(54) УСТРОЙСТВО ДЛЯ ДОПУСКОВОГО КОНТРОЛЯ АМПЛИТУДНО-ЧАСТОТНЫХ ХАРАКТЕРИСТИК ЧЕТЫРЕХПОЛЮСНИКОВ(54) DEVICE FOR ADMISSION CONTROL OF AMPLITUDE-FREQUENCY CHARACTERISTICS OF FOUR-POLES
II
Изобретение относитс к измери|тельной технике и может быть использовано дл проверки характеристик усилительной аппаратуры.The invention relates to a measuring technique and can be used to verify the characteristics of amplifying apparatus.
Известно устройство дл определени частотных характеристик, которое содержит последовательно соединенные генератор качающейс частоты , контролируемое устройство и индикатор, например электронно-лучевую трубку (ЭЛТ) D1.A device for determining frequency characteristics is known, which comprises a series-connected oscillating frequency generator, a monitored device and an indicator, for example, a cathode ray tube (CRT) D1.
Недостатком устройства вл етс низка точность измерений, обусловленна погрешност ми отсчета значений по измерительной сетке, нанесенной на экране ЭЛТ.The drawback of the device is the low measurement accuracy due to errors in the readout of values on the measuring grid printed on the screen of a CRT.
Известно также устройство дл наблюдени амплитудно-частотных характеристик САЧХ) и ее пол допусков на экране ЭЛТ, которое содержит генератор качающейс частоты, контролируемое устройство, согласующий усилитель , индикатор, преобразовательIt is also known a device for observing the amplitude-frequency characteristics of the ESSF) and its field of tolerances on a CRT screen, which contains a sweep frequency generator, a controlled device, a matching amplifier, an indicator, a converter.
частота-напр жение и два задатчика допусков 2.frequency voltage and two tolerance adjusters 2.
Недостатком этого устройства вл етс -низка точность -измерений, обусловленна нестабильност ми аналоговых элементов задатчиков допусков .A disadvantage of this device is the low accuracy of the measurements due to the instability of the analog elements of the tolerance adjusters.
Целью изобретени вл етс повышение точности контрол АЧХ.The aim of the invention is to improve the accuracy of control of the frequency response.
Цель достигаетс тем, что устрой10 ство дл допускового контрол АЧХ, содержащее управл емый генератор, к выходу которого подключен один из входов устройства, задатчик кода допусков и индикатор, введены пре15 образователь напр жение-код, цифровой вычитак ций блок, блок сравнени кодов, задатчик кода частоты, задатчик кода номинального уровн и блок управлени , первый выход которого The goal is achieved by the fact that a device for tolerance control of the frequency response, containing a controlled oscillator, to the output of which one of the device inputs, the tolerance code setter and the indicator is connected, a voltage-code generator, a digital readout unit, a code comparison unit, a setter are entered. frequency code, nominal level code setter and control unit, the first output of which
