Highland Technology logo
T560 DG features
  • Four TTL-level delay outputs, individually programmable for delay and pulse width range up to 10 s with 10 ps resolution
  • Low 20 ns insertion delay
  • Scenario generation for changing delay programs automatically
  • Pulse train generation creates unlimited number of pulses from a single trigger
  • DSP phaselock system maintains crystal-clock accuracy and jitter for any delay length; parts per trillion drift using external
    10 MHz reference
  • DDS synthesizer for internal trigger rates to 16 MHz
  • Programmable-level trigger input with divide/burst features and trigger GATE input
  • RS-232 serial interface standard; Ethernet optional
  • OEM packaged or board-only custom versions available
The T560 series is a family of small digital delay generators, intended for use in embedded OEM applications.

The T564 extends the capabilities of Highland's original T560 digital delay generator, allowing not only a single delay program, but a scenario of more than 8000 frames to be preloaded and then executed in rapid succession. Frames can be advanced automatically as triggers are received or simply stored and recalled manually. Each trigger generates four precise pulse outputs, independently programmable with 10 picosecond resolution in both delay and width. The T564 can generate single pulses per trigger as a standard digital delay generator or, new to the T560 DDG family, pulse trains

With the same low 20-ns insertion delay and 20-ps jitter as the T560, the T564 is ideal for timing and gating lasers, Q-switches, ICCDs, and other electro-optical devices, and for applying picosecond-resolution time trims to nuclear, radar, and sonar cabling and instrumentation. Additionally, the scenario capability allows moving target simulation in radar/sonar/lidar applications and sliding timing windows for margin testing--all with a form factor smaller than a paperback, with easy RS-232 or optional Ethernet control.

The T564-1 is the standard packaged version of the T564 DDG, suitable for many embedded applications, while the T564-2 adds Ethernet connectivity. The T560-9 evaluation package is also available.

Custom versions are readily available for OEM customers.
