Pulse voltage amplitude measurement device

The invention discloses a pulse voltage amplitude measurement device, which is characterized by comprising a high-voltage pulse attenuator and a digitizer. The low voltage output end of the high-voltage pulse attenuator is connected with the V+ end of the digitizer. The grounding end of the high-voltage pulse attenuator is connected with the V- end of the digitizer. Meanwhile, a measuring probe is reserved at the high voltage output end and the grounding end of the high-voltage pulse attenuator, respectively. The measuring probe at the high voltage output end of the high-voltage pulse attenuator is used for being connected with the voltage output terminal + end of the high-voltage power supply of to-be-measured equipment. The measuring probe at the grounding end of the high-voltage pulse attenuator is used for being connected with the voltage output terminal - end of the high-voltage power supply of to-be-measured equipment. According to the technical scheme of the invention, the digitizer and the high-voltage pulse attenuator are sufficiently large in bandwidth, sufficiently high in sampling rate, sufficiently fast in response speed, and sufficiently high in technical index of pulse voltage measurement. Therefore, the device can be used for quickly and accurately measuring the amplitude of the pulsed voltage.
