R&S®FSU67 with direct frequency range to 67 GHz

The R&S®FSU67 is based on the proven R&S®FSU spectrum analyzer family and offers the same comprehensive set of measurement functions and features, some examples:

  • Low noise floor: -152 dBm (1 Hz) at 2 GHz, -130 dBm (1 Hz) at 65 GHz
  • Wide range of resolution bandwidth: 1 Hz to 50 MHz
  • Versatile filter characteristics: Gaussian, channel filters, FFT, 6-dB EMI filters
  • Full range of detectors including RMS, quasipeak
  • Comprehensive power measurement functions (CP, ACP, time domain power)
  • R&S®NRP power heads can be connected directly (Option R&S®FS-K9 and R&S®NRP-Z6 required)
  • Harmonic distortion and spurious emissions measurement function
  • High display linearity < 0.1 dB
  • Phase noise and noise figure application firmware
  • External generator control for use of an external microwave generator as tracking generator for scalar network measurements
    • The full span sweep of the R&S®FSU67 shows a low noise floor up to 67 GHz.

    The full span sweep of the R&S®FSU67 shows a low noise floor up to 67 GHz.

    Subharmonics of multipliers, which are present despite filtering can be measured easily in relation to the wanted signal in one sweep even for a 50 to 67 GHz signal.
