Model 575 Digital Delay / Pulse Generator


  • 200pS Jitter Internal, 800pS External Trigger
  • Independent clock rates for each channel
  • Clock In & Clock Out
  • Programmable (Ethernet/USB/RS-232/GPIB)
  • Combine Electrical and Optical Outputs
  • Dual Inputs (2 Gate / Gate+Trig / 2 Trig) 250pS Delay & Width Resolution


  • Trigger, Gate, Delay, Pulse or Sync
  • Sync to an External Clock (up to 100 MHz)
  • Master/Slave or Multiple Unit Slave
  • Pulse Pick (up to 100 MHz)
  • Combine Pulses on One Channel

The Model 575 Digital Delay / Pulse Generator represents the latest in timing capabilities. With output configurations as varied as the applications the product serves, the Model 575 is clearly our most versatile instrument. We have combined advanced features such as a Labview/USB interface, complex burst sequences, and Divide-by-N and Setting Profiles with core technology in precision timing. Our 250pS Delay & Width resolution, and 200pS internal channel jitter, allow users great confidence in setting up an experiment or synchronizing multiple events.
