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-3 operates over a wider pulse width range of 2 to 15 ns, with amplitudes to 15V. The rise time is less than 150 ps, and the fall time is less than 800 ps.
