The GFT9404 module provides precision digital delay generation on the PXI platform.
It offers four independent delay channels (T0 to T3). The delay resolution is 1 ps, and external trigger to channel jitter is less than 50 ps. SMB outputs deliver 5 V, 2 ns rise time, under 50 Ω. Amplitude and width are adjustable on each output pulse.
The GFT9404 also offers four auxiliary delay channels to the front panel (AT0 to AT3). The copy of these four channels is provided on the PXI bus (PXI trig 0 to PXI trig 3). The delay resolution is 5 ns (one-time base clock) and trigger to channel jitter is 100 ps.
One input trigger (TRIG IN), PXI STAR trigger, or internal frequency, or soft trigger is used to trigger all output channels.
The control panel software for Windows provides a simple method to configure settings for each channel (amplitude, width, trigger source, trigger mode) and to control operation.
The GFT9404 is the ideal instrument to provide precisely timed pulse, as encountered in a picosecond laser system application.
