Rohde & Schwarz Cross correlation for phase noise analyzer R&S®FSWP8 from 1 MHz to 8 GHz (hardware option)
The R&S®FSWP-K55 cross correlation hardware option (part number 1322.9800.08) is designed for the R&S®FSWP8 phase noise analyzer, enabling cross correlation measurements from 1 MHz to 8 GHz. This option significantly improves phase noise sensitivity by allowing the analyzer to use two independent signal paths and perform cross correlation, thereby reducing the instrument's own noise contribution. The hardware is installed inside the R&S®FSWP8 and is essential for applications requiring ultra-low phase noise measurements, such as oscillator and synthesizer characterization. The option is fully integrated and controlled via the instrument's user interface, supporting automated measurement routines and advanced analysis features.
