The Quantum Composers 9250 Emerald Series Pulse Generator is a highly compact, advanced digital delay generator designed to allow synchronisation and manipulation of timing in complex experimental setups.
The Quantum Composers Emerald series is a compact, advanced delay generator capable of producing precisely timed electronic signals. These electronic signals can serve as a master clock source or trigger for experiments where a large number of actions must be synchronised in time. For each channel output, the signal width, delay and amplitude can be varied, allowing the user a huge amount of control.
