R&S®FS-K30 Application Firmware for Noise Figure and Gain Measurements for R&S®FSP, R&S®FSU and R&S®FSQ (preamplifier recommended, e.g. R&S®FSU-B23, R&S®FSU-B24, R&S®FSU-B25)

Outperforming any conventional noise measurement system

  • Overview

Key Facts

Application Firmware R&S®FS-K30 provides the high-grade analyzers with features otherwise only provided by special noise measurement systems.

Features

Frequency range up to 67 GHz (depending on analyzer model) for noise measurements in the micro wave range without requiring an additional downconverter

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.
