亚纳秒脉冲高电压测量探头
D-dot monitor for sub-nanosecond high voltage pulse measurement
摘要
Abstract
A kind of D-dot monitor has been designed to measure the high voltage pulse on an impedance transformer line of compact fast rise time pulse generator. The scaling factor of the D-dot monitor was calibrated in-situ by using a calibrated resistive divider and a high voltage pulse whose rise time is about 50 ns. The response of the monitor was tested by using a 50 Ω transmission line installed with the D-dot monitor. When the rise time of input pulse is about 320 ps, the rise time of the pulse output by the D-dot monitor is about 350 ps. The response of the D-dot monitor is about 150 ps. Thus the monitor can measure the voltage pulses with the rise time exceeding 450 ps. The experiment results indicate that the D-dot monitor can reliably and accurately measure the sub-nanosecond high voltage pulses.关键词
