The GFT1604 Mini Pulse & Delay Generator provides 4 (or 8 in option) independent delayed pulses. Delays up to 10 seconds can be programmed with 100 ps resolution and channel to channel jitter less than 50 ps RMS. An option allows to enhance delay resolution to 1 ps, and channel to channel jitter to 5 ps RMS.
SMB outputs deliver 1.5 V to 5 V, 2 ns rise time pulses, under 50 Ω. Pulse amplitude, polarity and width are adjustable on each output channel. In option, pulse amplitude can be 3 V to 10 V or 15 V to 50 V, under 50 Ω.
The model GFT1604 offer two inputs or two internal synchronized Timers (adjustable from 0.1 Hz to 50 MHz) or software command for triggering all selected delay channel. Either trigger rate may be set as one-shot or repetitive.
The generator uses an internal 100MHz TCXO clock reference, or an external user programmable (from 10 MHz to 240 MHz) clock (sine or square).
GFT1604 parameters can be remote controlled via USB to UART or Ethernet.
This generator is well suited to synchronise all the devices of Picosecond Laser System. In this application the “clock input” of the delay generator receives a reference signal (80 MHz for example) from a laser oscillator via an O/E (optical to electrical converter) and the delay generator provides single or repetitive pulses (adjusted in delay, amplitude, polarity and width) synchronized on “clock input” with very low jitter. From delay generator 4 GPIO under software control allow command to low frequency device of the Laser System for security or control.
