DSR400 10GbE

A Scalable, high-end Ethernet 10GbE Highly configurable digital signal recorder, optimized for all your needs. 

Record the signal, analyze it, then reconstruct the data back to the original!

The DSR400 Portbale is a high-end unified recording and playback machine for multi-channel wideband signals. It is a Signal Data Recorder and Playback System for SIGINT, ELINT & Advanced RADAR, MIMO & Wireless Standard.
The DSR400 Portbale is the successor of the DSR400 Prime. It is based on high-performance FPGA digitizing board, with 8-lanes PCI-Express host interface and high-performance RAID based Storage Servers.

EL-OR Systems design and engineer several high-speed recording platforms. After years of innovation in the field of RF and IF, we're proud to present this exceptional high-performance product.
