Abstract

Изобретение относитс к импульсной технике, а точнее к устройствам дл измерени нестабильности во времени параметров видеоимпульсов, и может быть использовано в радиотехнических устройствах, предназначенных дл тренировки и динамических испытаний ЭВП СВЧ. Цель изобретени - расширение функциональных возможностей за счет измерени коэффициента пропусков импульсов в заданном интервале времени. Введение в устройство дл измерени пропусков импульсов таймера 3, блоков /Б/ 4,12,16 управлени , счетчика 9 пропусков импульсов, счетчиков 13,17 синхроимпульсов, генератора 10 импульсов и счетчика 20 циклов позволило обеспечить возможность измерени коэффициента пропусков импульсов, зафиксированных в счетчике 20, в течение времени, задаваемом таймером 3. При этом измер етс и общее число пропусков. Процесс измерени синхронизируетс с помощью Б 4,12,16 управлени . Кроме того, устройство содержит шину 1 синхроимпульсов, входную шину 2, счетчик 5 пропусков, Б 6 регулируемой задержки, формирователь 7 импульсов, генератор 8 считывани . Б 11 сравнени , визуальный индикатор 14, переключатель 15 режимов работы, регулируемый источник 18 опорного напр жени и интегратор 19. 4 ил.The invention relates to a pulse technique, and more specifically to devices for measuring the instability in time parameters of video pulses, and can be used in radio devices designed for training and dynamic testing of microwave UHF. The purpose of the invention is to expand the functionality by measuring the pulse skip ratio in a given time interval. Introduction to the device for measuring pulses of timer 3, blocks / B / 4,12,16 of control, counter 9 of pulses, counters of 13.17 sync pulses, generator of 10 pulses and counter of 20 cycles allowed to ensure the measurement of the coefficient of pulses recorded in the counter 20, during the time set by timer 3. The total number of gaps is also measured. The measurement process is synchronized using control B 4,12,16. In addition, the device contains a sync pulse bus 1, an input bus 2, a counter 5 skips, an adjustable delay B 6, a pulse shaper 7, a read generator 8.
