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-2 family provides 120 Volt, < 2 ns output. The AVG-2A family offers the same amplitude, but offers a narrower < 1 ns output.
