New FSWX signal and spectrum analyzer with novel architecture overcomes limits of today's analysis methods

08/20/2025

Rohde & Schwarz introduces the brand-new FSWX signal and spectrum analyzer, the first multichannel signal and spectrum analyzer with multiple input ports, unlocking new possibilities in signal analysis. It is also the first instrument of its kind with a cutting-edge internal multi-path architecture enabling a novel cross-correlation feature. Combined with its low phase noise for high signal purity, its spurious-free dynamic range and its outstanding residual EVM, the FSWX delivers an RF performance like no other signal and spectrum analyzer in the market.

The instrument's wide internal bandwidth of 8 GHz allows for comprehensive analysis even of complex waveforms and modulation schemes. Combined with a high measurement speed and analysis tools tailored to the user’s needs, the FSWX brings new levels of performance and precision to signal analysis for modern RF applications – from active RF components testing to state-of-the-art automotive radar testing to complex airborne radar scenarios and satellite test in A&D applications to the latest test challenges in WLAN and cellular technologies like 5G and beyond.

Michael Fischlein, Vice President Spectrum & Network Analyzers, EMC & Antenna Test at Rohde & Schwarz, is thrilled to introduce the new FSWX: "Our team has truly re-imagined signal and spectrum analysis technology with our new FSWX. They have come up with an innovative architecture and design to empower our customers to tackle complex measurement scenarios in the evolving landscape of wireless communications and radar technology that were previously unattainable. In other words, the FSWX makes measuring the impossible, possible." The instrument’s innovative design features include multiple input ports, cross-correlation capabilities, advanced filter banks and broadband ADCs.
