The Berkeley Nucleonics Model 577 is the latest model in a series of pulse/delay generators with industry-leading precision, rich feature sets and a multitude of user-friendly form factors. This benchtop model offers 4 or 8 independent outputs that are designed to provide cutting-edge features, precision time and amplitude domain control and cost-effective overall system costs. Our pulse/delay generators synchronize multiple pulses for a wide range of applications, and offer a host of optical/electrical input and output options. The delay and pulse width for each channel is independent and digitally controlled which makes the instrument ideal for situations that require synchronizing several different events, bursts and nested bursts, and different channel operating modes.
