Product overview

The R&S®FSWP is a high-sensitivity phase noise analyzer that combines very low noise internal sources with cross-correlation, so the phase and amplitude noise of a stable source such as a radar oscillator is measured in seconds. Spectrum analysis, vector signal analysis and VCO characterization sit on the same platform, and external mixers take the frequency range up to 325 GHz — for demanding aerospace, defense, communications and radar work.

Key features

  • Cross-correlation: highly sensitive, simultaneous amplitude and phase noise measurement on CW and pulsed signals
  • Fastest measurement speed in its class: hardware-accelerated signal processing gives real-time phase noise results with the fewest cross-correlations
  • Unrivaled sensitivity: the internal low noise sources outperform most commercial signal generators on the market
  • Pulsed signal analysis: automatic pulse parameter detection, supporting phase noise measurements on radar sources
  • Automated VCO characterization: frequency, power, tuning slope and phase noise against tuning voltage
  • Residual phase noise measurement: measure the noise a component adds, driven by an internal or external source, under realistic operating conditions
  • Allan variance: frequency stability figures calculated directly from the phase noise data
  • One instrument, many functions: spectrum analysis, vector signal analysis and transient measurements in the same box
  • Frequency extension to 325 GHz: millimeterwave measurements with the FS-Z family of external mixers

Typical applications

  • Verification of radar system signal sources
  • Testing DROs (dielectric resonator oscillators) and OCXOs (oven-controlled crystal oscillators)
  • VCO characterization during component development
  • Characterizing pulsed signal sources for military and aerospace use
  • Additive (residual) phase noise measurements on components
  • PLL transient response analysis
