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.
