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-2-C provides amplitudes up to 15V, with pulse widths variable from 0.25 to 2 ns. The rise time is less than 100 ps, and the fall time is less than 250 ps.
