Description
Изобретение относитс к радиотехнике и может использоватьс в радиоизмерительной технике дл контрол амплитудночастотных характеристик (АЧХ) и чувств вительности приемников импульсных сигна лов.The invention relates to radio engineering and can be used in radio measuring equipment for monitoring amplitude-frequency characteristics (AFC) and sensitivity of receivers of pulse signals.
По основному авт. св. № 473965 известно устройство дл автоматического контрол амплитудно-частотных характ&ристик импульсных приемников, содержа- шее измеритель частотных характеристик (ИЧХ) с детекторной головкой, к выходу которого подключены компенсационный вход автокомпенсатора и последовательно соединенные аттенюатор, смеситель с г&теродином , линейный тракт исследуемого приемника, выход:, которого соединен с входом автокомпенсатора, выходы последнего соединены с детекторной головкой и входом видеотракта исследуемого пригемника , состо щего из последовательно соединенных амплитудного детектора и видеоусилител , датчик отношени мгнобенных значений видеосигналов, один его-вход соединен с выходом амплйтудно- According to the main author. St. No. 473965, a device for automatic control of amplitude-frequency characteristics of pulse receivers, containing a frequency response meter (IHF) with a detector head, the output of which is connected to an autocompensator compensation input and a series-connected attenuator, a mixer with h & receiver, output: which is connected to the input of the autocompensator, the outputs of the latter are connected to the detector head and the input of the video path of the test attachment consisting of Consequently, the amplitude detector and the video amplifier are connected, the ratio of the moment values of the video signals, one of its inputs is connected to the output of the amplitude-
го детектора, другой - с детекторной го ловкой, а выход через ключевой элемент, управл емый формирователем импульса строба, св занным с входом ИЧХ, соединен с регистрирующим элементом flT.the other, with the detector head, and the output through a key element controlled by a strobe pulse former connected to the input of the IHC is connected to the recording element flT.
Однако известное устройство имеет низкую помехозашишенность, что приводит к снижению очиости контрол .However, the known device has a low noise immunity, which leads to a decrease in the sensitivity of the control.
Целью изобретени вл етс повышение точности контрол путем повышени помехозащищенности устройства.The aim of the invention is to improve the accuracy of control by increasing the noise immunity of the device.
Дл этого в предлагаемое устройство дл автоматического контрол АЧХ импульсных приемников введены дополнительный ключевой элемент и пороговый блок; при этом выход амплитудного детектора подключен к входу порогового блока, выход которого подключен к управл ющему входу ключевого элемента, сигнальный вход последнего соединен с выходом датчика отношени мгновенных значений видеосигналов , а выход соединен с шшюй заземлени .For this, an additional key element and a threshold unit are introduced into the proposed device for automatic control of the frequency response of the pulse receivers; the output of the amplitude detector is connected to the input of the threshold unit, the output of which is connected to the control input of the key element, the signal input of the latter is connected to the output of the sensor of the instantaneous values of video signals, and the output is connected to the earth ground.
