R&S®M3SR Multiband, Multimode, Multirole Stationary/Shipborne Radio for Air Defense/Navy
New software radio generation with embedded operating system and parameter setting via software
Brief description
R&S M3SR (multiband, multimode, multirole stationary/shipborne radio) is a new software radio generation with embedded operating systems and parameter setting by means of software. This means that the radios can be reprogrammed regarding waveforms, RF and AF characteristics, and external interfaces.
Applications
- Navy
- Civil ATC
- Air defence and military ATC
- Mobile sheltered applications
The outstanding novel feature of these radio units is the possibility of enhancing their functionalities by loading new application software. Their functionalities can be redefined by software downloads. Device settings can be made locally via the menus of the Local Comfort Control Panel R&S GB4000C (CCP) or via a remote comfort control unit (CCU). The basic units already come with a large variety of features that were optional for the R&S Series400U. Software and hardware options are available to provide the radio units with additional EPM (ECCM) waveforms such as SATURN, HAVE QUICK or R&S SECOS.
Frequency ranges of basic units
- VHF/UHF radios: 100 MHz to 512 MHz (without gap)
- UHF radios: 225 MHz to 399.975 MHz
Modularity
All R&S M3SR units are based on the uniform Radio Basis R&S KR4400, which consists of a mechanical frame, the radio platform (main board) and the audio front panel. The radio basis is among others responsible for AF signal processing and is independent of the RF-specific modules.
Depending on the desired radio equipment configuration, radio modules such as main receiver, synthesizer or guard receiver can be inserted. A transmitter module with integrated DC/DC power supply is fitted for transmitters and transceivers. Independently of these modules, six free slots for user-specific plug-in cards are provided on the rear of the unit.
Receivers and multireceivers have an integrated AC/DC power supply. An external power supply is required for AC operation of transmitters and transceivers. The external Universal Power Supply R&S IN4000A is available for this purpose.
Local control
The basic radios come standard without a local comfort control panel, a blank panel being fitted instead. If local control is required, the optional Local Comfort Control Panel R&S GB4000C (model .02) has to be ordered. Passwords are assigned to user groups such as operators or maintenance staff to prevent unauthorized access to the equipment configuration.
Remote control
The radio features full remote control capability. All control functions can be made via the R&S GB4000C (model .03). All relevant settings including the configuration of the radio can also be made from the remote control unit. All the basic radios are fitted with two serial and two LAN interfaces as standard.
Amplifier concept
Due to the use of a universal broadband amplifier, only one antenna connector is used irrespective of the frequency range. Should for special applications the VHF and UHF frequency ranges have to be operated separately, an external diplexer (e.g. R&S FT224 in reverse mode) is available.
