The AVO-2 series of solid-state pulse generators is designed for pulsing laser diode and other low impedance loads with rectangular current pulses as high as 10 Amperes and pulse widths as high as 50 ns. The diode load is connected in series with a lowvalue current limiting resistor between two output solder terminals (i.e., OUT and GND). Model AVO-2A-B provides output amplitude variable from 0 to 5A, with a pulse width variable from 4 to 50 ns. The rise times are 2.5 ns or less, and the fall times are 3.5 ns or less.
