R&S FSVR Real Time Spectrum Analyzer


R&S FSVR Real-Time Spectrum Analyzer


Brief Description

The R&S®FSVR combines a full-featured signal and spectrum analyzer with a real-time spectrum analyzer. In real-time operation, the R&S®FSVR seamlessly measures and displays the spectrum in the time domain with a span of up to 40 MHz. As a result, it captures every event for analysis, no matter how brief that event might be.


Key Facts

  • Frequency range from 10 Hz to 7 GHz, 13.6 GHz, 30 GHz or 40 GHz
  • 40 MHz real-time analysis bandwidth for:
  • Triggering on frequency masks
  • Measurement applications for cellular standards, wireless connectivity standards and general purpose, e.g. phase noise, noise figure, vector signal analysis, etc.
  • Frequency range up to 110 GHz with the R&S®FSVR30 or R&S®FSVR40, the R&S®FSV-B21 option and the R&S®FS-Z60/-Z75/-Z90/-Z110 harmonics mixers
  • Spectrum with persistence function
  • Spectrogram display
  • Display of power versus time
