Description

Outperforming any conventional noise measurement system
Key Facts Application Firmware R&S®FS-K30 provides the high-grade analyzers with features otherwise only provided by special noise measurement systems. At a specified frequency or in a selectable frequency range the following parameters can be measured:
  • Noise figure in dB
  • Noise temperature in K
  • Gain in dB
Compared to conventional noise measurement systems, R&S®FS-K30 used with the Analyzers R&S®FSP/FSU or R&S®FSQ has the advantage that a large variety of further RF measurements can also be performed.
Features & Benefits
  • The combination of Application Firmware R&S®FS-K30 and Analyzers R&S®FSP/FSU or R&S®FSQ offers the following advantages over conventional noise measurement systems:
    • Frequency range up to 67 GHz (depending on analyzer model) for noise measurements in the micro wave range without requiring an additional downconverter
    • Resolution bandwidths variable in steps of 1/2/3/5 (R&S®FSP: only 1/3) for optimum matching to narrowband DUTs
    While conventional noise measurement systems are only suitable for determining the noise and gain characteristics of the DUT, the R&S®FSP/FSU or R&S®FSQ also allow the highly sensitive measurement of the following parameters:
    • Harmonics
    • Intermodulation
    • Spurious responses
    and many other RF-relevant criteria (for highly sensitive measurements on amplifiers and measurements on frequency converting DUTs, e.g. low noise converters).
  • Noise measurements
    • Level range 0 dB to 25 dB
    • Resolution 0.01 dB
    • Measurement accuracy ±0.2 dB (measurement with preamplifier (gain 20 dB, noise figure 5 dB) and 1 MHz bandwidth, valid for DUTs with noise figure 1 dB to 10 dB and gain >10 dB)
  • Gain measurements
    • Level range 0 dB to 60 dB
    • Resolution 0.01 dB
    • Measurement accuracy ± 0.2 dB (preamplification 20 dB, noise figure 5 dB, bandwidth 1 MHz)
    For improved accuracy and repeatability of measurements a preamplifier (Option FSx-B25) is strongly recommended.
