Model AVR-DV1-B is a high performance, GPIB and RS232-equipped test system designed to produce waveforms suitable for phototriac dV/dt test requirements. More specifically, the AVR-DV1-B mainframe generates a 500 ns to 200 us pulse with amplitude adjustable up to +1000V or -1000V. The rise and fall times of this pulse are < 100 ns. This pulse is applied to the supplied test fixture. An adjustable series resistance and a fixed capacitance are present in the test fixture. Together with the 50 Ohm output impedance in the mainframe, these generate a lowpass filter. The resulting 1%-63.2% rise time (T) is 125 ns to > 1.1 us, approximately.
