R&S®FSU Spectrum Analyzer

The world's fastest, most accurate spectrum analyzer with the highest dynamic range

Key Facts
Picture R&S®FSU Spectrum Analyzer

LXI Class C conformant

The R&S®FSU spectrum analyzers are performance leaders in dynamic range, phase noise, level accuracy, and resolution bandwidth - all factors that are essential for the user's ability to design, characterize, and manufacture next generation wireless elements.

Excellent performance:

  • Frequency range 20 Hz to 3.6 GHz, 8 GHz, 26.5 GHz, 43 GHz, 46 GHz, 50 GHz and 67 GHz
  • Displayed average noise level -158 dBm (1 Hz)
  • Phase noise typ. - 133 dBc ( 1Hz) at 10 kHz
  • TOI typ. +25 dBm
  • Resolution bandwidth 1 Hz to 50 MHz
  • Displayed average noise level with preamplifier R&S®FSU-B24: typ. - 168 dBm (1Hz) at 20 GHz, typ. - 155 dBm (1Hz) at 50 GHz

R&S®FSU67 - First spectrum analyzer with a direct frequency range to 67 GHz and fundamental mixing:

  • Simplified test set-ups with just one connection from 20 Hz to 67 GHz
  • Full span sweep of 67 GHz
  • Unambiguous frequency indication without the image response and multiple responses known from external harmonic mixers
  • Wider level range with a much higher allowable reference level than with harmonic mixers
  • Good level accuracy to 67 GHz
  • Low noise floor: -152 dBm (1 Hz) at 2 GHz, -130 dBm (1 Hz) at 65 GHz

High measurement speed:

  • Fast ACP in time domain
  • Up to 70 measurements per second (including trace transfer via GPIB)

Unmatched number of features:

  • Measurement routines for TOI, MC ACP(R), OBW, CCDF, APD, etc. as standard
  • Application firmware available for GSM/EDGE, Bluetooth®, WCDMA/HSDPA/TD-SCDMA, CDMA2000®/1xEV-DV/1xEV-DO, …
