The Model 575 digital delay/pulse generator combines a multichannel pulse generator and digital delay generator in a single benchtop instrument.

Available now from Berkeley Nucleonics, the Model 575 digital delay/pulse generator combines a multichannel pulse generator and digital delay generator in a single benchtop instrument. Two instruments can be side-by-side in a single-width rack. A true pulse generator provides independent control of rate, delay and width with an external trigger.

The 575 is the only multichannel unit to permit differing rates for all the channels.

Using new clock-divider functions, for example, the user can operate one channel at 20MHz, another at 5MHz, and another at 50Hz.

There is an option for a separate external trigger input for each channel also, or use the standard configuration (common trigger for all channels).

Pulse generators do not offer fine resolution and accuracy of delays and widths that a digital delay generator does.

The 575, on the other hand, provides 250ps resolution and up to 1ppm accuracy for delay and widths.

Rate, selected by period, is set to a resolution of 10ns.

Before the Model 575, the market for digital delay generators did not offer separate internal triggering rates for each of the channels.

Now each channel can use the internal clock, a multiple of the internal clock (clock-divider), or one of two external trigger input connectors.

For those that cannot use a common external trigger, this unique 'trigger per channel option' is well suited.

Modular output boards provide a variety of output options.

The growing family of output stages include both TTL and adjustable amplitude, 35V high voltage electrical and LED-optical at either 820 or 1310nm.

For those working only with optical triggering, an optical input is also available.

Off-the-shelf transmitter/receiver pairs are used so one can easily match their output to our input and our outputs to their inputs.

The 575 also offers USB and RS232 programmability as standard.

An additional communications module includes GPIB and Ethernet.

Berkeley's standard programming protocols are backwards compatible, and LabView drivers are already available.

In addition to onboard storage, programming functions can be used to store a 'setting profile' of each setup, and import the same setup to any unit at a later time.

As the industry has come to expect, Berkeley has loaded many advanced features and application support tools into the product as well.

For example, trigger increment offers a means for incrementing delay times after each trigger.

In this case, users can select the delay increment and the start and stop points.

Another is illuminated on, a backlight that illuminates on each channel during a pulse condition, and goes dark when the pulse train is stopped.

Dual-gating uses two input signals, electrical or optical, to act as a set of gate pulses for any selected channels.

Using dual-gating, users can enable (disable) channels during certain desirable (undesirable) events without an additional instrument to provide gate control.

Clock-in functionality gives the user the ability to use a master clock from another device.

These clocks may range from 10 to 100MHz.

'Our latest design includes features to keep your experimentalists excited'.

'We are proud to introduce the Model 575 and expect it will address demands for years to come', says President David Brown.
