DESCRIPTION
The NL405 Width Delay is a digitally controlled pulse duration generator and is used to produce precise pulses of adjustable duration with high accuracy and repeatability. This module combines many of the features of the discontinued NL401 Digital Width and NL403 Delay/Width into a single unit.
The NL405 produces TTL logic output pulses (of both polarities) that have a duration set using three decades of thumbwheels and a seven (7) position range switch. It also features a press to start button, LED indication of an output and a separate logic output signal at the end of the defined WIDTH time. It was designed as a replacement for the NL401 and, in most places where the NL403 would have been used.
