Berkeley Nucleonics Model 525 6-Ch Digital / Pulse Delay Generator

The Berkeley Nucleonics Model 525 Digital/Pulse Delay Generator offers six channels of pulse delay and width control in a compact design.  Intuitive front and rear panel controls allow start and stop, active indicators, and trigger options.  This enables users to orient outputs on either the front or back of the instrument for benchtop or rackmount use.  A simple PC software interface allows control of the delay generator from any PC, enabling the adjustment of delay from trigger, pulse width, when to trigger, or burst control.

The Model 525's USB interface eliminates the need for bulky front panel components. The timing and triggering flexibility is remarkable, with 20MHz rep rates, 2ns timing resolution, <50ps RMS jitter and internal or external triggering options. Outputs can be selected for each channel, giving users the ability to trigger, gate, or pulse various devices in a research project with different requirements. Single Pulse, Continuous, Burst, Duty Cycle and Cycle Counting are all selectable options for each channel. Wide pulses are also possible, with a width range of 10ns – 1000s and a delay from trigger range up to 1000s. External triggering is enabled with signals up to 30V peak and widths as low as 20ns on the rising or falling edge. 

A unique feature of the Model 525 Pulse Generator is the ability to combine the timing of any or all channels together and output them to any of the output connectors. The multiplexing function (MUX) can be set through remote communications via a computer.  The Model 525 offers additional inputs and outputs for external clock synchronizing.   A convenient negative delay feature can reference one channel with respect to another channel in positive or negative time increments. By allowing a channel to reference another channel as its trigger, it is possible to synchronize the channels with respect to each other.
