The AVMM series features a 300 ps rise time, pulse width variable from 1 to 10 ns and an output pulse width which is independent of the output amplitude control setting. In addition, a variable rise time option is available (300 ps to 2 ns in 5 discrete steps). The output amplitude for all models is controlled by a front-panel oneturn control. A second one-turn control varies the pulse width. Models AVMM-2 provide output amplitudes variable up to 5 Volts respectively with pulse width variable from 1 to 10 ns.
