    • Extension to 40 channels


The GFT1020 generator provides twenty independent delayed output pulses on the rear panel. Delays up to 10 second can be programmed with 100 ps resolution (or 1 ps in option) and channel to channel jitter is less than 25 ps. BNC outputs deliver up to 6 V level under 50 Ω. Amplitude and Width are independently adjustable for each output pulse.

One input trigger (TRIG IN), or one of the three synchronized internal generator or command is used to trigger all output channels. A T0 output pulse marks zero delay for each trigger.

All parameters (delay/amplitude/polarity/width/trigger source for each channel …) may be locally controlled over touch panel and remotely controlled over Ethernet and Internet (Internal web server) interface (10 / 100 Mb/s).

The GFT1020 is well suited to synchronize all the equipments of a Picosecond Laser System with only one compact unit and one GUI. In this application the “Clock input” of the delay generator receives a reference signal from laser oscillator (80 MHz for example) and the delay generator provides single or repetitive pulses synchronized on “clock input” with  very low jitter.
