GFT1404 8 Channel Digital Delay Generator

GFT1404 8 Channel

Summary

Greenfield Technology's GFT1404 PXI Digital Delay Generator offers eight channels with four completely independent delay channels (T0 to T3), and four auxiliary delay channels on the PXI bus (PXI trig 0 to PXI trig 3). In system mode, the module is optical triggered by the GFT3001 via an optical network. Delay resolution on the primary outputs is an impressive 1 ps, and channel to channel jitter is < 50 ps. SMB outputs deliver 5V, with a 2 ns rise time into 50 Ω. Amplitude and width are completely adjustable on each output pulse. The GFT1404 auxiliary channels' delay resolution is one time base period and trigger to channel jitter is less than 100ps.

Free control panel software GUI for Windows provides a simple method to configure settings for each channel (delay, output amplitude, output width), trigger source, trigger mode, and to control the state of the instrument. The configuration information of the instrument can be stored to disk and restored. The software is designed to allow one GFT1404 and multiple GFT9404 to be installed and operate in the same PXI chassis. Each module is specified by its serial number.
