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)
