Description

Импульс управлени  от дискриминатора 4 перестраивает блок управлени  и соответственно генератор тока 1 на более низкий уровень тока. Путем последовательных проб по снгналам задающего генератора и амплитудного дискриминатора блок управлени  устанавливает в управл емом генераторе тока такую величину тока, при которой дискриминатор 4 не срабатывает. Состо ние блока управлени  сравниваетс  при помощи схемы сравнени  9 с величиной тока, заданного при помощи блока уставок 8, и индицируетс  в виде величины тока на цифровом индикаторе 7 и индикаторе годности 10. Предмет изобретени  Устройство дл  измерени  и контрол  максимально допустимого тока полупроводниковых приборов в режиме лавинного пробо , содержащее задающий и управл емый генераторы тока, блок управлени , индикаторы и устройство дл  подключени  испытуемых приборов , отличающеес  тем, что, с целью увеличени  надежности испытаний при неразрушающем контроле, к дной из клемм устройства дл  подключени  через запоминающий блок подключен амплитудный ди-скриминатор , выход которого соединен с управл емым генератором тока, к этой же клемме через накопитель подключен выход управл емого генератора тока, с входами которого соединены задающий генератор и блок управлени , к последнему подключены задающий генератор, индикатор, амплитудный дискриминатор, схема сравнени , вход которой соединен с блоком уставок, а выход - с индикатором годности .The control pulse from discriminator 4 rearranges the control unit and, accordingly, the current generator 1 to a lower current level. By successive sampling of the master oscillator and amplitude discriminator, the control unit sets such a current in the current generator that the discriminator 4 does not operate. The state of the control unit is compared using the comparison circuit 9 with the current value set using the setting unit 8, and is displayed as a current value on the digital indicator 7 and the validity indicator 10. Subject of the invention Device for measuring and monitoring the maximum permissible current of semiconductor devices avalanche sample containing master and controlled current generators, control unit, indicators and device for connecting the tested devices, characterized in that, in order to increase the reliability of the test with non-destructive testing, an amplitude dialer, the output of which is connected to a controlled current generator, is connected to the bottom of the device terminals, the output of the controlled current generator is connected to the same terminal through the accumulator, and the input generator is connected to the same terminal the control unit, the master oscillator, the indicator, the amplitude discriminator, the comparison circuit, the input of which is connected to the settings block, and the output with the life indicator are connected to the latter.
