Description

В ОСНОВНОМ авт. св. N° 122542 описано устройство дл  измерени  затухани  нелинейности четырехполюсников. В этом устройстве дл  получени  уверенных отсчетов производилось сужение полосы пропускани  индикатора уровн  продукта нелинейности. Процесс измерени  с помощью известных устройств состо л в настройке по выходному индикатору блока выделени  на ту гармонику (или комбинацию), по которой производитс  измерение затухани  нелинейности. Затем производилось сравнение затуханий в измер емом и эталонном каналах. При этом необходимо отметить, что частоты колебаний на выходе обоих каналов точно равны между собой. Недостаток известного устройства состоит в том, что по вл ютс  трудности при из ieнeнии больших (пор дка 16 и более иепер) величин затухани  нелинейности.BASIC Auth. St. N ° 122542 describes a device for measuring the attenuation of non-linearity of quadrupoles. In this device, to obtain reliable samples, the bandwidth of the nonlinearity product level indicator was narrowed. The measurement process using known devices consisted in setting the output indicator of the allocation unit to the harmonic (or combination) used to measure the non-linear attenuation. Then, the attenuation in the measured and reference channels was compared. It should be noted that the oscillation frequencies at the output of both channels are exactly equal to each other. A disadvantage of the known device is that it is difficult to select large (on the order of 16 or more) non-linear attenuation values.

В описываемом устройстве указанный недостаток устранен путем использовани  взаимно коррел ционного приемника с синхронным детектором .In the device described, this disadvantage is eliminated by using a mutually correlation receiver with a synchronous detector.

Блок-схема устройства дл  измерени  затухани  нелинейности четырехполюсника приведена на чертеже.A block diagram of a device for measuring the attenuation of a non-linearity of a quadrupole is shown in the drawing.

Электрические колебани  от измерительного генератора / через регулировочный магазин 2 затуханий и фильтр 5 нижних частот поступают в измер емый объект 4. Кроме того, колебани  генератора поступают в блок 5 выделени  продуктов нелинейноети. Этот блок состоит из усилител -ограничител  и резонансного перестраиваемого усилител . Усилитель выдел ет колебани  той частоты, дл  которой в данный момент производ т измерени  затухани  нелинейноети.The electrical oscillations from the measuring generator / through the adjustment damping store 2 and the low-pass filter 5 enter the measured object 4. In addition, the oscillations of the generator enter the nonlinear network output unit 5. This unit consists of an amplifier-limiter and a resonant tunable amplifier. The amplifier emits the oscillations of the frequency for which the nonlinear attenuation is currently being measured.

Выделенна  частота колебаний с блока 5 выделени  поступает на регулируемый фазовращатель 6, с помощью которого выравниваютс  фазовые сдвиги между измерительным каналом и каналом сравнени . Фазовращатель 6 через стабилизатор с термистром 7 и образцовый магазин 8 затухани  соединен с одним входом ключа 9 сравнени . Другой вход ключа 9 соединен е выходом измер емого объекта 4. Выход ключа 9 через фильтр 10 верхних частот и усилитель 11 индикатора подан на синхронный детектор 12. Другой вход синхронного детектора соединен с выходом стабилизирующей  чейки, с которой на синхронный детекторThe selected oscillation frequency from the allocation unit 5 is supplied to the adjustable phase shifter 6, with which the phase shifts between the measuring channel and the comparison channel are aligned. The phase shifter 6 is connected via a stabilizer with a thermistor 7 and an exemplary damping store 8 to one input of the comparison key 9. The other input of the key 9 is connected by the output of the object being measured 4. The output of the key 9 through the high-pass filter 10 and the amplifier 11 of the indicator is fed to the synchronous detector 12. The other input of the synchronous detector is connected to the output of the stabilizing cell, to which the synchronous detector
