The IZT R4000 delivers an immensely powerful digitizer, wideband receiver and signal collection system for COMINT and ELINT systems, wideband satellite surveillance and continuous broadband radio signal recording. It achieves an instantaneous bandwidth of 120 MHz and covers an impressive frequency range of up to 18 GHz.

IZT’s third generation all-digital receiver boasts a very high dynamic range also in high-bandwidth applications, and has the ability to store and analyze the huge amounts of data that come with this increased instantaneous bandwidth in a typical operating environment.

To provide you with a powerful and reliable system that can analyze multiple signals, the IZT R4000 features a backend digital storage system and dedicated parallel signal analysis engines to support multiple users. It includes highly-selective configurable signal pre-selectors to avoid signal overload problems, high-quality RF front-ends, and broadband digitizers.

Choose from three IZT R4000 models to meet your signal intercept and monitoring requirements: the IZT R4000-RF3, the IZT R4000-RF6 with a frequency range of up to 6 GHz ideal for interferometric direction finding and radio monitoring, and the IZT R4000-RF18 with a frequency range of up to 18 GHz.
