R4000

The IZT R4000 is a third-generation digital wideband receiver and recording platform designed for Communications Intelligence (COMINT), Electronic Intelligence (ELINT), satellite monitoring, and broadband RF signal collection. Delivering up to 120 MHz of instantaneous bandwidth, it combines high-dynamic-range RF front ends, broadband digitization, and parallel signal processing to simultaneously capture, analyze, record, and process multiple signals. Its modular architecture and multiple frequency extension options make the R4000 an ideal solution for defense, intelligence, and spectrum monitoring applications.
