Design and test of a fast capcitive high voltage probe

We designed a fast capacitive high voltage probe for a Marx generator. Since the capacitive probe works on differential mode, we designed also a fast passive integrator to integrate the signals. We tested the probe´s performance by using a simple pulse generator to simulate the Marx generator signals. We calibrated the probe using a calibrated water load which act as a resistive voltage divider. We present and discuss the results of the experiments.
