New DG645 8 channel digital delay/pulse generator

Stanford Research Systems DG645

We are proud to announce the launch of a new 8-channel digital delay/pulse generator, the DG645 from Stanford Research Systems, now available in the UK from Lambda Photometrics.

The DG645 digital delay/pulse generator is an improved version of its predecessor, the DG535 with <25ps rms jitter, up to 10MHz repetition rate, higher accuracy and with more channels.

The front panel has five outputs, T0 and four independent pulses (AB, CD, EF, GH). The programmed delays can be set between 0 and 2000 seconds, with 5ps resolution, to control the timing of the leading and trailing edges of the four output pulses. There are three optional delay output configurations to choose from, and each configuration has eight delay channels with 5V, 30V or combinatorial outputs.

The DG645 can be triggered internally or externally. The internal rate generator can be set from 100µHz to 10MHz with 1µHz resolution. An external trigger input can trigger a timing cycle, a burst of cycles or a single shot. A trigger inhibit input is included as standard which can disable the trigger or any of the pulse outputs during a timing cycle.

Ovenized crystal and Rubidium timebases are available as an option if higher stability is required. GPIB, RS232 and Ethernet interfaces are included as standard, allowing remote control for all instrument functions.
