Stanford DG535 Digital Delay/Pulse Generator

High accuracy, low jitter and wide delay range

Stanford Research Systems

 

The DG535 Digital Delay and Pulse Generator from Stanford Research Systems provides four precisely-timed logic transitions or two independent pulse outputs. The delay resolution on all channels is 5ps and the channel-to-channel jitter is less than 50ps. Front-panel BNC outputs deliver TTL, ECL, NIM or variable level (-3 to +4V) pulses into 50? or high impedance loads. The high accuracy, low jitter and wide delay range make the DG535 ideal for laser timing systems, automated testing and precision pulse applications.

 

Features:

  • Four independent delay channels
  • Two fully-defined pulse channels
  • 5ps delay resolution
  • <100ps rms jitter
  • Adjustable amplitude and offset
  • Delays up to 1000 seconds
  • Standard GPIB interface
  • Optional ±32V

Delay Outputs
There are four delay out channels: A, B, C and D. The logic transitions of these outputs can be delayed from an internal or external trigger by up to 1000 seconds in 5ps increments. The T0 pulse, which marks the beginning of a timing cycle, is generated by the trigger signal. The insertion delay between an external trigger and the T0 pulse is about 85ns.

 

Pulse Outputs
In addition to the four delay outputs, there are four pulse output channels: AB, -AB, CD and -CD. The leading edge of the AB pulse coincides with the leading edge of the earlier of A or B, and the trailing edge of AB coincides with the leading edge of the later of B or A.

 

Output Amplitude Control
Each delay and pulse output has an independently adjustable offset and amplitude which can be set between -3V and 4V with 10mV resolution. The maximum transition for each output is limited to 4V. In addition, you can also separately select 50? or high impedance termination for each output. Preset levels, corresponding to standard logic families, can also be selected. TTL, NIM and ECL levels can all be selected with a single key press.
