The Model 745T-20C Digital Delay Generator provides users with an amazing twenty independent channels of pulse delay and width. This multi-channel Digital Delay Generator provides delay resolution of 100 picoseconds (ps) with an optional 1 picosecond (ps) resolution. The jitter is less than 25 ps with internal or external triggers.
The Model 745T-20C delivers 6 V into 50 ohms, meeting all TTL applications. The levels are adjustable on a channel-by-channel basis giving you complete time and amplitude domain control. The fast outputs, with risetimes of 1 ns, are on the rear panel for an elegant look for complex experiments. The front panel controls are accessed by a touchscreen interface with several programming options (Ethernet, etc) for remote control.
All parameters (delay/amplitude/width/trigger….) may also be controlled with an embedded GUI that opens in an HTML browser such as Internet Explorer, Firefox, or Chrome at 10 or 100 Mb/s rates.
The Model 745T-20C is uniquely suited to gate, delay, pulse and synchronize many experiments in the nanosecond and picosecond domain. The space saving, reduced calibration costs, and simple control of so many channels are ideal for users of multiple channels of timing.
The Model 745T-20C Digital Delay Generator offers users several options for triggering timing channels: External, Internal and Remote. Externally trigger on the positive slope. The internal rep rate generator may be started by front panel pushbutton or remotely via your software interface. Either trigger mode may be set in one-shot or repetitive.
Expand to 40 or 60 Channels
The Model 745T-20C can be expanded to provide up to 60 channels, all with the same high performance. *Note: external triggering is not available for 40 / 60 channels.

Frequently asked Questions
Model 745T-20C | What if I need more than 20 channels of timing in my system ?
The Model 745T-20C offers 20 channels per enclosure and can be daisy chained with additional units to a single trigger. However, for complex multi-channel applications, contact the factory. We can offer a custom card-level solution which may be more cost effective.
