Quick links

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)
  • Optional preclassifier detects LPI signals and summarizes individual results into a condensed result

Innovative DF antennas

  • Active/passive switchover with just a mouse click
  • Exceptionally high DF sensitivity
  • Integrated, extendible lightning protection
  • Easy replacement of DF antennas

Powerful receive path

for signal measurement

  • Special and exceptionally powerful receive path
  • Improved analog architecture of the receive path
  • Especially powerful analog/digital converters
  • Considerable advantages in the case of weak signals and dense signal scenarios

Powerful hardware

developed by Rohde & Schwarz

  • In-house development and manufacture of all DF system components, including the DF antenna
  • Signal processing at maximum speed based on powerful FPGAs
  • Use of powerful Rohde & Schwarz ASICs
  • High immunity to strong signals thanks to sophisticated preselection

Effective measurements

In line with ITU recommendations

  • R&S®DDF550 fulfills all ITU recommendations for  direction finders and receivers.
  • Option for comprehensive, ITU-compliant measurement methods including, for example: Frequency and frequency offset, field strength, modulation, spectrum occupancy and bandwidth

Multichannel signal processing

  • Multichannel signal detection and analysis in a networked system
  • Parallel multichannel output of more than 100 channels
  • Multichannel digital downconversion (DDC) signal extraction from the R&S®DDF550 realtime bandwidth with R&S®DDF550DDCE and R&S®CA120FFP
  • Automatic detection of fixed frequency and burst signals with R&S®DDF550-HRP and R&S®CA120DSC
  • Automatic detection of frequency agile short-time signals with R&S®DDF550-ST
