GFT9404 Digital Delay Generator

GFT9404 8 Channel

Summary

Greenfield Technology's GFT9404, 8 Channel Digital Delay Generator PXI module provides four completely independent delay channels (T0 to T3). The delay resolution offers an impressive 1 ps step size and external trigger to channel jitter at < 50 ps. SMB outputs deliver 5V, with 2 ns rise time, into 50 Ω. Each output provides independent amplitude and width are adjustment.

The GFT9404 provides four additional auxiliary delay channels to the front panel (AT0 to AT3), along with four mirror channels 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 100ps.

One input trigger (TRIG IN), PXI STAR trigger, or internal frequency is used to trigger all output channels.
