Description

The invention relates to the field of pa; i, electronics and electronics, and can be used to manufacture gas discharge circuits, such as clipper diodes, when they are measured and their electrical parameters are known for measuring ignition voltage and time of operation of clipper devices in which these electrical parameters are known but the oscilloscope is measured with a voltage divider, for example, a compensated one.

However, this ycTpoiicTBo has a high error in measuring the electrical parameters of gas-discharge devices (more than 50%) when the levels of the supplied and measured signals are incommensurable.

The purpose of the invention is to improve the accuracy of measuring the electrical parameters of gas discharge devices and to eliminate the influence on the oscilloscope of the incommensurability of the levels of the supplied and measured sigals.

The goal is achieved by connecting the oscilloscope to the opposite side and the transientor, between the base and the emitter of which are connected in parallel the source of the direct displacement and the prohibiting emulsion generator, while the anode of the diode and the collector of the transistor are connected to the output of the oscilloscope.

The ignition voltage is measured using an oscilloscope with respect to the voltage drop O ,, on the device equal to 100-250 volts for gas discharge devices. With this amplification, the oscilloscope can be increased into units and ten times the distortion of the sigpal, not received1, to the oscilloscope input, since the effect of incommensurability of the supplied and measured sigals can be reduced to a minimum by adjusting the moment of application to the base of the transistor prohibiting any sigal.
