Key Facts

The R&S®FSL-K30 application firmware provides the R&S®FSL spectrum analyzer with features otherwise only provided by special noise measurement analyzers.

The following parameters can be measured at a specified frequency or in a selectable frequency range:

  • Noise figure in dB
  • Noise temperature in K
  • Gain in dB

Compared with conventional noise measurement systems, R&S®FSL-K30 has the advantage that a wide variety of further RF measurements can also be performed.

The R&S®FSL-K30 is also available for the R&S®ZVL3 and R&S®ZVL6 Vector Network Analyzers (with the R&S®ZVL-K1 spectrum analysis option and the R&S®FSL-B5 additional interfaces option).

Features & Benefits

  • The R&S®FSL also allows the measurement of harmonics, intermodulation, spurious responses and many other RF-relevant criteria (for measurements on amplifiers and on frequency-converting DUTs, e.g. low-noise converters).

  • Noise measurements
    • Measurement range 0 dB to 35 dB
    • Resolution 0.01 dB
    • Measurement accuracy ±0.3 dB (measurement with external preamplifier (gain 30 dB, noise figure <5 dB) and 1 MHz resolution bandwidth, valid for DUTs with noise figure 1 dB to 10 dB and gain >10 dB)
  • Gain measurements
    • Measurement range 0 dB to 60 dB
    • Resolution 0.01 dB
    • Measurement accuracy ±0.2 dB (measurement with preamplifier (gain 30 dB, noise figure <5 dB) and 1 MHz resolution bandwidth)
  • Required hardware
    • R&S®FSL-B5 noise source power supply (via 28 V connector on the R&S®FSL rear panel)
    • Noise source, e.g. NoiseCom NC346
    • External preamplifier (for improved accuracy and repeatability of measurements)
