Digital Delay Generators
Highland has introduced three unique features to digital delay generation: a "Queued Updates" feature allows time settings to be changed without
corrupting ongoing timings; a "Train" feature allows multiple pulses to be generated from each trigger; and a "Frames" feature allows complex delay
sweeps and pulse scenarios to be pre-loaded and rapidly executed. Digital delay and pulse generators are available in 1-6 channels, with square,
Gaussian, and arbitrary waveshapes, and insertion delays as low as 10 nanoseconds.
Generates delays up to 1000 seconds in 1 picosecond increments, on four separately programmable delay-and-width outputs.
- 25 nanosecond insertion delay
- < 10 picosecond RMS jitter typical
- 1 picosecond resolution
