The GFT3001 synchronizes local delay generators over an optical network by generating an optical data serial data stream, as well as through master triggers and a time base. The clock reference of the GFT3001 can be external or internal. In some applications, the GFT3001 can also generate a clock to synchronize other devices (Laser, Oscillator, etc.). The GFT3001 can respond to an external hardware single-shot trigger, or generate an internal single-shot trigger. To prevent erroneous outputs, the user can stop the single-shot with a hardware-level preset.

An additional security measure is in place if the external clock reference is lost, returning the GFT3001 to a preset frequency. All parameters may be locally controlled over front panel, and remotely controlled over an Ethernet (10 / 100 Mb/s) or Internet (internal web server) interface.

The main application of the GFT3001 is in facilitating picosecond timing systems, generating severalhundred trigger pulses to equipment across the different situations encountered in large Laser timing Systems.
