The main application of the R&S Series400U is voice and data communication especially for defence use.

Civil aviation
The R&S Series400U radios are used for emergency backup ATC communication, in addition to a conventional single-channel radio system for many simultaneous frequencies. They are added either as emergency radio units switched manually by the supervisor via the voice switching system to the controller’s position or as standby radios embedded in redundant radiocommunication systems with automatic channel selection and main/ standby switchover.

Defence
The R&S Series400U has special features and benefits for air traffic control and tactical multichannel operation, for voice and data application, in plain and fixedchannel mode. Options and add-on units for COMSEC or TRANSEC complete the program. The R&S Series400U includes HAVE QUICK EPM (ECCM) radio equipment for the forces in NATO countries or associated countries or R&S SECOS EPM (ECCM), with embedded COMSEC, for other export customers.

Fixed - transportable - mobile
R&S Series400U equipment is provided for fixed installation (in ground-to-air radio centers), for transportable use (in radio shelters) as well as for mobile applications (in ships or vehicles). It is designed for installation in 19" racks. Its modular concept provides cost-effectiveness. As the modules are of identical design and interchangeable, they can be used with different types of equipment without modification.

Local radio control
is possible via the keyboard and the alphanumeric and window-structured LED display of the Control Unit R&S GB453.

Remote control
Depending on the used interface options R&S Series400U communication equipment offers a wide variety of remote control possibilities:

  • V.24/RS-232-C/RS-485: point-to-point or bus operation via separate control lines from R&S GB406-type control units
  • DTMF (dual tone multiple frequency) code according to ITU-T recommendation Q 23: point-to-point operation via private or public telephone (= AF) line, saving costs for leased lines
