ABSTRACT:
A device for the testing and monitoring of the function of a shock wave or pressure wave source is provided. The testing and monitoring device is characterized in that a passive non-linear transmission element transforms very short shock wave pulses received by it, the shock wave pulses typically having pulse durations lasting a few microseconds, into a considerably lower frequency range, whose oscillations are then sensed and evaluated.
