The AVRH series of pulse generators consists of three basic models providing output amplitudes in the range of 2000 to 3000 Volts into high impedance loads. Model AVRH-3-B provides up to 3000 Volts out (to R great than less than 10 k ohm) with rise and fall times of 100 ns and pulse widths variable from 200 ns to 2.5 us. The pulse repetition frequency (PRF) is variable from 0 to 1.0 kHz, with a 0.25% duty cycle limit.
