Abstract
A high voltage probe is described which is based on the principle of consecutive differentiation and integration. The voltage to be measured is applied to a coupling capacitor of a few μμF and rated at several tens of kilovolts. The capacitor is connected to a cable which propagates a signal proportional to the derivative of the voltage. At the other end of the cable a transistorized integrator integrates the current and produces a signal proportional to the voltage. It is thus possible to obtain a bandwidth of 300 Hz to 200 MHz.
