1 / 4
The R&S®FSW50 is a high-performance member of the FSW series designed for precision signal analysis across RF, microwave, and emerging millimeter-wave bands. It excels in demanding scenarios like 5G NR (FR1/FR2), satellite communications, radar testing, and component characterization, balancing wide frequency coverage, ultra-low noise, and advanced analysis capabilities.
