To ensure secure radiocommunications and successful accomplishment of missions, today's stationary radiocommunications solutions for civil and military applications must meet extremely demanding RF requirements and also provide high operating reliability. The R&S®M3SR Series4400 software defined radio family is designed for stationary civil and military secure voice and data communications. It features high modularity and outstanding specifications.


The R&S®M3SR Series4400 radios provide continuous AM and FM transmission coverage from 100 MHz to 512 MHz. The radios were developed in line with international civil air traffic control guidelines and standards (ICAO Annex 10, EN 300676). The radios also fulfill UHF communications requirements in line with EN 302617.


The R&S®M3SR Series4400 offers military customers a wide range of interfaces and associated proprietary frequency hopping waveforms, as well as radiocommunications in line with NATO standards. Military data transmission methods such as LINK11 and LINK22 are supported. To ensure that existing R&S®M3SR Series4400 systems remain up-to-date, their functionality can be enhanced through subsequent software downloads and, if necessary, by using new hardware modules.
