Description
Предметом изобретени вл етс электронный частотомер с широким диапазоном частот, в котором дл получени пр моугольных импульсов использован мультивибратор.The subject of the invention is an electronic frequency meter with a wide frequency range, in which a multivibrator is used to receive square pulses.
Схема частотомера изображена на чертеже и состоит в основном из следующих элементов: усилительной лампы 1, мультивибратора, собранного на двух лампах 2 и 3 и двух триодов, работаюпшх как выпр мители .The frequency meter circuit is shown in the drawing and consists mainly of the following elements: an amplifying lamp 1, a multivibrator assembled on two lamps 2 and 3, and two triodes working as rectifiers.
С целью управлени началом и концом процесса опрокидывани в схеме мультивибратора, сетка лампы 3 включена на анод усилительной лампы /, на сетку которой подано исследуемое напр жение. На анод этой же лампы через сопротивление 4 подано напр жение с анода лампы 2 мультивибратора.In order to control the beginning and end of the tipping process in the multivibrator circuit, the grid of the lamp 3 is connected to the anode of the amplifying lamp /, on the grid of which the test voltage is applied. The anode of the same lamp through the resistance 4 is supplied from the anode of the lamp 2 of the multivibrator.
Дл градуировки диапазона измер емых частот служат сопротивлени 5-8 и конденсаторы 9-12. Схема предусматривает возможность записи показаний частотомера путем включени самопишущего прибора 13.For calibration of the range of measured frequencies, resistors 5–8 and capacitors 9–12 are used. The scheme provides for the ability to record the readings of the frequency meter by turning on the recorder 13.
Предмет изобретени Subject invention
Электронный частотомер с использованием дл получени пр моугольных импульсов мультивибратора , отличающийс тем, что, с целью управлени началом и концом процесса опрокидывани в схеме мультивибратора, сетка второй лампы последнего включена на анод дополнительной лампы, на сетку которой подано исследуемое напр жение , а на анод через сопротивление подано напр жение с анода первой лампы мультивибратора.An electronic frequency meter using a multivibrator for receiving rectangular pulses, characterized in that, in order to control the beginning and end of the tilting process in the multivibrator circuit, the grid of the second lamp of the latter is connected to the anode of the additional lamp, to the grid of which the test voltage is applied, and to the anode through resistance is applied from the anode of the first multivibrator lamp.
