Abstract
Изобретение относитс к радиоизмерительной технике и позвол ет измер ть врем переключени частоты генератора с электрической перестройкой, а также наблюдать процесс переключени частоты. Целью изобретени вл етс повышение точности измерени времени переключени частоты. Устройство дл измерени времени переключени частоты содержит генератор 1 с электрической перестройкой частоты, гетеродин 2, блок 3 управлени , смеситель 4, усилитель 5 промежуточной частоты , регистрирующий блок 9 и гетеродин 10. Введение частотного дискриминатора, переключаемого фильтра 8 нижних частот, модул тора 11, смесител 12, индикаторного блока 13, фильтра 14 нижних частот и блока 15 выборки и запоминани позвол ет повысить точность и достоверность измерений, а также визуально наблюдать сам переходной процесс изменени частоты. 5 ил.The invention relates to a radio measuring technique and allows measuring the switching time of an electrically tuned generator frequency, as well as observing the frequency switching process. The aim of the invention is to improve the accuracy of measuring the switching frequency. The device for measuring the switching frequency includes a generator 1 with electrical frequency tuning, local oscillator 2, control unit 3, mixer 4, intermediate frequency amplifier 5, recording unit 9 and local oscillator 10. Introduction of a frequency discriminator, switchable low-pass filter 8, modulator 11, the mixer 12, the indicator unit 13, the low-pass filter 14 and the block 15 for sampling and memorization allows to improve the accuracy and reliability of measurements, as well as visually observe the transition process of changing frequency. 5 il.
