The models in the AVM family provide very fast rise times (100 or 150 ps), with high repetition rates (to 25 MHz), variable pulse widths, and amplitudes as high as 20 Volts. Model AVM-4-C provides peak outputs to 20 Volts, pulse widths variable from 0.5 to 4.0 ns and will operate at PRFs up to 10 MHz.
