pulse signal generator

Abstract

The invention relates to a pulse signal generator comprising a DC high voltage source, a voltage display unit, a coaxial current-limiting unit, a TLP circuit, a pulse control unit, a drive amplification unit and a frequency counting and display unit. The DC high voltage source is used for converting alternating current commercial power into continuously adjustable direct current. The coaxial current-limiting unit is used for controlling size of charging current of the TLP circuit which is used for generating a nanosecond-level high current pulse signal. A frequency signal outputted by the pulse control unit is amplified by the drive amplification unit and then controls a working mode of the TLP circuit. The frequency counting and display unit counts and displays the frequency signal generated by the pulse control unit. A situation that existing pulse signal generators cannot output pulse signals which are rapid in rising period of time and short in action time is solved by the pulse signal generator. The pulse signal generator is the device capable of generating the pulse signal which is rapid in rising period of time, short in action time and wide in amplitude dynamic range so that a requirement of anti-interference performance assessment of an electronic device can be met.

Description

technical field [0001] The invention relates to an interference signal generation device, in particular to a pulse signal device capable of generating a pulse signal with fast rising time and falling time, short action time and large amplitude dynamic range. Background technique [0002] With the development of electronic technology, all kinds of equipment are generally electrified. The anti-interference performance of electronic equipment has attracted more and more attention. Of course, the anti-interference performance of the designed and manufactured electronic equipment can be determined by testing it in various on-site noise environments. However, since the disturbances generated in the field are mostly accidental and random, the test takes a long time and is likely not to be repeated. Once it occurs, it is often too late to use various means to find out which part of the circuit has malfunctioned. Therefore, there is a need for an interference source device, which ...
