Description
задержки 10, формирователь 11 стробирующих импульсов., delay 10, the driver 11 gating pulses.,
Устройство работает следующим образом .The device works as follows.
С выхода генератора 1 точной амплитуды импульс напр жени с пологим Задним фронтом поступает на сумматор5Г ваничитель 4 непосредственно, а также через прецизионный резистивный делитель напр жени 2 и исследуемый блок 3. На выходе сумматора-ограничител 4 формируетс и импульс напр жени , амплитуда которого пропорциональна интегрсшьной нелинейности исследуемого блока 3.From the output of the exact amplitude generator 1, a voltage pulse with a gentle trailing edge is fed to the adder 5G vanitel 4 directly, as well as through a precision resistive voltage divider 2 and the block 3 under study. nonlinearity of the block 3.
Одновременно с импульсом измер емого сигнала с дополнительного выхода генератора точной амцпитуды снимаетс импульс синхронизацииj который задерживаетс блоком задержки 10 на врем , равное длительности сигнала с иссле- . дуемого блока 3 от его начала до момента вершины. От переднего фронта задержки сигнсша на выходе формировател 11 стробирующих импульсов формируетс короткий импульс, открывающий ключевой элемент 5.Simultaneously with the pulse of the measured signal, a synchronization pulse j is removed from the additional output of the generator of exact ampicide, which is delayed by the delay unit 10 for a time equal to the duration of the signal from the probe. block 3 from its beginning until the vertex. From the leading edge of the signal delay, at the output of the gating pulse generator 11, a short pulse is formed, which opens the key element 5.
Сигнал с выхода ключевого элемента 5 выпр мл етс детектором 6. В установившемс состо нии этот сигнал имеет незначительную величину. Выпр мленное напр жение через усилитель 7 и фильт 8 поступает на измерительный прибор 9 посто нного тока.The signal from the output of the key element 5 is rectified by the detector 6. In the steady state, this signal has a negligible amount. The rectified voltage through the amplifier 7 and filter 8 is fed to the measuring device 9 direct current.
При экспериментальной проверке предложенного устройства удалось повысить точность измерени интегральной нелинейности с 0,05 до 0,01fO,015%,In the experimental verification of the proposed device, it was possible to improve the measurement accuracy of the integral nonlinearity from 0.05 to 0.01fO, 015%,
