The Model 525 represents a revolutionary new pulse generator that offers full function in a compact and cost effective package. At just 7.125“ x 5.1“ x 1.5” this is one of the smallest units available, but you will not be disappointed in its performance, features, or programmability. Finally, a low-cost pulse generator that does not sacrifice performance or function.
The Model 525's interface is USB only, which eliminates the bulky front panel components and reduces the potential for mechanical problems. The timing and triggering flexibility is outstanding, 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. Trigger externally with signals up to 30 V peak and widths as low as 20ns on the rising or falling edge.
One of the more unique features of the Berkeley Nucleonics pulse generators is the ability to combine the timing of any or all channels together and output them out of any of the output connectors. The multiplexing function (MUX) can be set through remote communications via a computer.
Selectable Clock Reference
The Model 525 offers additional inputs and outputs for external clock synchronizing. User selectable input and output reference frequency (10 MHz to 100MHz). Synchronize with the Mode Lock Oscillator of a laser or phase lock multiple units with one clock.
Flexible Gating Options
The Model 525 is packed with gating options for almost any setup. You may gate individual channels or gate all. Gate immediately (output inhibit) or gate after a pulse (pulse inhibit).
External Trigger Options
Select channels for internal(free run) / external triggering. Triggered channels have flexible output choices: single pulse, burst at its clock rate, continuous pulse train or a series of on/off pulses (duty cycle).
Each channel can have individual channel rates (either T0 or integer division of T0).
Use the convenient negative delay feature to 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, you can synchronize the channels with respect to each other.
Note that Negative Delay cannot trigger a channel before your initial trigger. It is intended to complement the channel referencing option.
