- Datasheet


The GFT1020 generator provides twenty independent delay channels on the rear panel. Delay up to 10 seconds 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 6 V level under 50 Ω. Amplitude and Width are independently adjustable for each output pulse. Options include:
  - Output amplitude can be 2.5 V to 10 V, or 5 to 20 V, or fixed 32 V, or 250 mW optical pulse.
  - The number of delay channels can be extended to 40 channels

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/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 devices of a Picosecond Laser System with only one compact unit and one GUI.
