It was designed by [[Fred Beckett]], [[Dennis Feucht]], [[Tom Hill]], and [[Gary Kersey]].
Pulses can be triggered by an external input, a manual trigger button, or an internal period generator (optionally gated by the trigger input).
Pulses can be triggered by an external input, a manual trigger button, or an internal period generator (optionally gated by the trigger input).
The trigger signal can be undelayed, delayed by a selectable time, or both (in which case double pulses are generated).
