The Model 588B rackmount pulse generator delivers high-density timing in one chassis. Choose twelve channels in 1U or twenty-four in 2U, with up to thirty-six independent outputs. Every channel shares one low-jitter timebase: 250 ps delay resolution, 1 ns plus 0.0001 times the period accuracy, and channel-to-channel jitter below 5 ps RMS. An external clock reference keeps the rack synchronized, with USB, RS232, and Ethernet control standard. Built for precision laser triggering and high-speed photography.
