Key facts

  • High DF accuracy, sensitivity and immunity to reflections
  • High DF scan speed due to outstanding 80 MHz realtime bandwidth (V/U/SHF)
  • Easy integration into mobile platforms 
  • DF antennas with integrated, extendible lightning protection
  • Direction finding of signals in the frequency range up to 6 GHz

Fast and precise direction finding

The fast R&S®DDF550 wideband direction finder offers outstanding realtime bandwidth and DF scan speed as well as high DF accuracy, sensitivity and immunity to reflections.

Features & benefits

High DF scan speed

Direction finding of short-duration signals

  • High probability of interception
  • High DF scan speed due to outstanding 80 MHz realtime bandwidth
  • Direction finding of short-duration and frequency agile signals with high probability of intercept
  • Enhanced measurement speed (option)

Reliable DF results

Even in challenging environments

  • Higher immunity to reflections due to DF antennas with a very large number of antenna elements (VHF/UHF/SHF)
  • Stable bearings in VHF/UHF/SHF range even with a 50 % share of reflections

Precise direction finding and accurate location

Even for weak and short-duration signals

  • High DF sensitivity due to large number of antenna elements
  • Adjustable coherent signal integration in wideband DF and DF scan mode for enhanced DF sensitivity
  • GPS based synchronization of multiple R&S®DDF550 (time-synchronized DF scan mode)
