The GFT745T generator provides four independent delay channels (A to D) to front panel. The delay resolution is 1 ps, and external trigger to channel jitter is less than 25 ps. BNC outputs deliver 5 V, 1 ns rise time into 50 Ω. Amplitude and width are adjustable on each output pulse. One input trigger (TRIG IN), or two internal synchronized timers, or software command is used to trigger all output channels. A T0 output pulse is time reference of the delay and generates at each selected trigger.The GFT745T also provides (in option) four auxiliary delays channels E to H to front panel. The delay resolution is 1.25 ns and trigger to channel jitter is less than 50 ps.
