Rohde & Schwarz Cross-Correlation for phase noise meas. application R&S®FSW3-KM129 required (software license) (portable license)
The R&S®FSW-KM129 is a software license option for the R&S®FSW signal and spectrum analyzer series, enabling cross-correlation for phase noise measurements. This feature enhances phase noise sensitivity by using two independent signal paths and cross-correlating their outputs, significantly reducing the instrument's own noise contribution. The KM129 option is essential for applications requiring ultra-low phase noise analysis, such as oscillator and synthesizer characterization. The portable license allows flexible use across different compatible R&S®FSW analyzers, supporting advanced measurement scenarios in R&D and production environments.
