Abstract : A method and device for testing protection circuits comprising positive positive and negative high voltage protection circuits and high voltage fast rise time protection circuits. A bipolar tests signal with alternate positive and negative high voltage pulses is applied to the circuit under test. Determination is made whether the pulses are within a predetermined voltage window. Signals indicating pass/fail responsive to that determination are generated. A high voltage fast rise time negative pulse is applied to the circuit under test. Changes in the voltage-time waveform are sensed and compared to predetermined levels. Pass/fail signals are generated in response to the comparison. (Author)
