The Greenfield GFT9404 module provides precision digital delay generation on the PXI platform. It offers four independent precision delay channels capable of 1 ps delay resolution and four auxiliary delay channels with a 5 ns delay resolution. Each delay output is configurable in terms of amplitude and width definition. The GFT9404 features driver support for Windows OS as well as an NI-VISA-based LabVIEW instrument driver.
