The Model 745T is a compact, 4-channel benchtop digital delay generator offering 250 femtosecond delay resolution across a 20-second delay range. RMS jitter runs as low as 5 ps for short internally triggered delays and under 25 ps for externally triggered delays. An optional four-channel auxiliary block adds 1.25 ns-resolution outputs. Controlled via touchscreen, Ethernet, or USB, the 745T supports laser timing, pulse picking, component testing, ATE, and precision defense and research instrument triggering applications.
