The AVIR series is designed for 200V applications requiring pulse widths from 2 to 1000 ns, at repetition rates up to 50 kHz. The AVIR-1 family provides output amplitudes continuously variable from 0 to 200 Volts (into 50 Ohms), pulse widths variable from 2 ns to 5 ns, with 1 ns rise times. The maximum pulse repetition frequency is 50 kHz. Instruments with the -B suffix include a complete computer control interface.
