The Model 725 multi-trigger delay generator coordinates complex experiments from eight independent timers, eight inputs, and eight outputs. Programmable boolean logic (AND, OR, XOR, negated) combines triggers before they fire. Delay resolution is 10 ns, trigger-pulse delay spans 20 ns to 1370 seconds, and throughput delay runs 10 ns typical with jitter of 50 ps from an internal source. Runs stand-alone or under PC control via timerPRO or LabVIEW. Built for ballistics and multi-input synchronization.
