针对现有快沿脉冲信号幅度不足，无法有效实现高压探头上升时间参数测量的难题，提出了一种高压快沿脉冲信号的产生方法。该方法基于单传输线型脉冲成形原理，使高压脉冲信号在传输线上进行传播，最后在匹配的大功率阻抗上产生一个具有明显顶部特征的矩形波。测试结果表明该矩形波幅度可达2 kV，前沿的上升时间小于500 ps。通过对两款高压探头上升时间参数进行测量，实验结果验证了该方法产生的高压快沿脉冲信号适用于高压探头上升时间参数的校准。

In view of the fast pulse signal amplitude is too low to measure the rise-time parameter of high-voltage probe,a method of the high-voltage fast edge signal generation is proposed. The method is based on the pulse-forming principle with a single transmission line. A rectangular wave is generated on a matched impedance through the transmission of the high-voltage pulse signal in the line. The test results show that the rectangular wave amplitude can reach 2 kV and the front rise-time is less than 500 ps. By measuring the rise-time parameters of two high-voltage probes,the ezperimental results prove that the high-voltage pulse signal generated by this method is applicable for high-voltage probe calibration.
