Digital Signal Receivers

RF Spectrum Receivers

The IZT R4000 delivers an immensely powerful digitiser, 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.

The all-digital receiver boasts a very high dynamic range also in high-bandwidth applications, and has the ability to store and analyse the huge amounts of data that come with this increased instantaneous bandwidth in a typical operating environment. It features a backend digital storage system and dedicated parallel signal analysis engines to support multiple users. Further, the R4000 includes highly-selective configurable signal pre-selectors to avoid signal overload problems, high-quality RF frontends, and broadband digitisers.
