Product ID: PSG-3
The PSG-3 is a four-channel pulse/delay generator. It can be used as a master clock for timing and delay control. It can be externally triggered or gated by an external event. Pulse width, delay, repetition rate, and other timing parameters can be controlled by one of two available interfaces
