Radio direction finding on multiple channels
Key facts
  • Parallel direction finding on up to 32 maritime channels with the same high DF accuracy and sensitivity on all channels
  • Quasi-simultaneous direction finding on additional channels outside the maritime frequency range, e.g. distress channels
  • Seamless coverage of a wide frequency range from 118 MHz to 250 MHz (with R&S®ADD090)
  • Adaptive interference cancellation (option) in instances where VHF radiocommunications antennas are installed on the same mast as the DF antenna
  • Output of results to vessel traffic management systems via a serial interface (option) or TCP/IP interface
  • Serial interface compatible with R&S®DDF100M (option)

Brief description The R&S®DDF200M digital direction finder represents the latest generation of traffic control direction finders. Radio direction finding for maritime traffic control is performed simultaneously on multiple frequency channels using only one direction finder.
Features & Benefits
  • One direction finder for all frequency channels
