Description

Насто щее изобретение относитс  к устройствам дл  сн ти  импульсных характеристик ферритовых сердечников, используемых, например, в запоминающих схемах. Такие устройства содержат: тенератор испытательных импульсов, подаваемых на намагничивающую обмотку провер емого феррита, генератор нилообразных импульсов низкой частоты, модулирующих напр жение основного генератора, и катодный осциллограф, на горизонтальные пластины которого подаетс  огибающа  падени  напр жени  с шунта, включенного в намагничивающую цепь феррита, а на вертикальные - напр жение с выходной обмотки провер емого феррита.The present invention relates to devices for capturing the impulse responses of ferrite cores used, for example, in memory circuits. Such devices include: a generator of test pulses applied to the magnetizing winding of the tested ferrite; a generator of low frequency nilo pulses modulating the voltage of the main generator; and for vertical ones, the voltage from the output winding of the ferrite being tested.

Предлагаемое устройство отличаетс  от известных тем, что в нем в качестве генератора модулирующего напр жени  применен генератор падающего пилообразного напр жени .The proposed device differs from the known ones in that an incident sawtooth generator is used as a modulating voltage generator.

Такое выполнение устройства позвол ет уменьшить погрешности отечета, вызванные пульсаци ми огибающих напр лсений, наблюдаемых на экране осциллографа.Such an embodiment of the device makes it possible to reduce swelling errors caused by pulsations of envelopes observed on the oscilloscope screen.

На чертеже изображена блок-схема предлагаемого устройства. Управл ющее пилообразное напр жение с частотой около 20 гц подаетс  с генератора / падающих пилообразных импульсов на генератор 2 испытательных импзльсов. Генератор / модзлирует импульсы генератора 2 по амплитуде, после чего они подаютс  на намагничивающую обмотку провер емого феррита 3. Возникающие при этом импульсы напр жени  в выходной обмотке провер емого феррита подаютс  на линейный усилитель 4 и усиливаютс  до уровн , необходимого дл  линейной работы импульсного детектора 5. Затем с помощью детектора 5 и низкочастотного фильтра 6 выдел етс  огибающа  выходных импульсов, котора  через парафазный усилитель 7 посто нного тока подаетс  на вертикальные пластины электронно-лучевой трубки 8. На горизонтальные пластины электронно-лучевой трубки 8 подаетс The drawing shows a block diagram of the proposed device. A control sawtooth voltage with a frequency of about 20 Hz is fed from the generator / incident sawtooth pulses to the generator 2 test pulses. The generator / modulates the generator 2 pulses in amplitude, after which they are fed to the magnetizing winding of the tested ferrite 3. The resulting voltage pulses in the output winding of the tested ferrite are fed to the linear amplifier 4 and amplified to the level required for the linear operation of the pulse detector 5 Then, using the detector 5 and a low-pass filter 6, the output envelope of the pulses is extracted, which is fed through a paraphase amplifier 7 of direct current to the vertical plates of the cathode-ray tube 8. On the horizontal plates of the cathode ray tube 8 is provided
