The AVG series of high voltage impulse generators includes units providing pulse widths (measured at the 20% rise time point) in the range of 1 to 10 ns, amplitudes from 120V to 1 kV, and pulse repetition rates to 50 kHz. All models require a 50 Ohm load. The AVG-3B family provides 420 Volt, < 2.7 ns outputs.
