Sage Laboratories introduces its newest addition to the IFM/DFD family of products. The FDFD7409-4 is a broadband (2 to 18 GHz) digital frequency discriminator incorporating a pulse detector/processor. Processing pulse widths as narrow as 80 ns up to CW, the DFD provides fast and accurate identification of threats. With ultra-low power consumption and small, lightweight packaging, this cost-effective model continues to build the Sage legacy of high-capability instantaneous frequency measurement receivers. This model is available with an optional VME interface as well as 50 ns pulse capability.
