Digital Reprogrammable Software Radios M3SR Your key to interoperability ◆ High operational flexibility while on mission ◆ Interoperability with existing radios according to international standards ◆ Easy system integration ◆ Low life cycle costs ◆ Software download of new waveforms ◆ High growth potential through P3I (preplanned product improvement)
Radio Basis KR4400 The various models are set up on the hardware and software of the Radio Basis KR4400, which forms the central and common part of all M3SR radios. The radio basis is independent of the RFspecific modules. Additional radiospecific hardware and software modules define the performance features of the radio.
Key features of the modules The modules have the following outstanding features: ◆ Independent use of all modules (no alignment or manual adjustment when modules are replaced) ◆ Central download of software and firmware, either locally or remotely (no need to open the radio unit) ◆ Data exchange via radio module bus ◆ Type label with bar code identification down to PCB level (fast automated detection and identification) ◆ All modules with electromagnetic shielding (maximum EMC/EMI immunity) ◆ All settings m
Internal AC/DC Power Supply IN4400A The IN4400A is the internal AC/DC power supply required for receiver and multireceiver radio types. Its submodules are an AC/DC converter and a DC/DC converter. The AC/DC converter delivers DC from the external mains supply. The IN4400A is located instead of the transmitter module. The external Universal Power Supply IN4000A is required for transceivers or transmitters.
Built-in test (BIT) concept Radio failure archive An efficient BIT concept allows identification and location of functional failures down to module level. All failures detected during the test can be indicated locally and remotely. All failures detected and error messages are stored in the radio failure archive. The archive can be read locally on the CCP and remotely. Each entry also contains a description in plain text.
Specifications for basic fixed-frequency radio Common data for transmitter, transceiver and receiver radio configurations Receiver data Sensitivity Unless stated otherwise, specs are valid for the frequency range from 108 MHz to 174 MHz and 225 MHz to 400 MHz.
