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 1.2 ns in 5 discrete steps). The output amplitude for all models is controlled by a front-panel one-turn control. A second one-turn control varies the pulse width. Models AVMM-1-C and AVMM-2-C provide output amplitudes variable up to 2 and 5 Volts respectively with pulse width variable from 1 to 10 ns while Model AVMM-3-C provides up to 10 Volts with a pulse width variable from 1 to 5 ns.
The pulse repetition frequency is variable from 3 kHz to 25 MHz using the internal clock oscillator that is controlled by a six-position frontpanel switch and a one-turn fine control. A delay control and a sync
output are provided for sampling scope triggering purposes. The units can also be triggered externally using a TTL-level pulse. The propagation delay in the externally triggered mode is typically 30 ns and an optional variable relative delay (0 to 5 ns) is available.
