Rohde & Schwarz has unveiled the FSWX, an innovative multichannel signal and spectrum analyzer, setting a new standard in precision RF testing.
Engineered with a forward-looking strategy centered on flexibility, signal clarity, and user-centric features, the FSWX is the first analyzer with multiple synchronous input ports and an internal multi-path architecture, bringing transformative benefits to engineers and researchers working across wireless, radar, and aerospace domains.
Innovation at the Core
At the heart of the FSWX lies unprecedented architectural innovation:
Multiple input ports enable simultaneous signal acquisition, empowering complex, real-time analysis of systems such as beamforming antennas in 5G and radar.
Its multi-path signal architecture with internal cross-correlation capability effectively removes internal instrument noise, unlocking deeper insights with superior sensitivity and clarity.
Unlike traditional analyzers that depend on YIG filters, the FSWX employs broadband ADCs and filter banks, achieving both wideband performance and spurious-free dynamic range across the full frequency spectrum.
These advancements are not mere incremental improvements — they redefine what’s possible in signal analysis, allowing users to push the boundaries of technology development in communications, defense, and aerospace.
Strategy: Built for the Evolving Test & Measurement Landscape
The FSWX reflects Rohde & Schwarz’s strategic pivot toward:
Multichannel signal environments: Addressing the growing need for synchronized, high-bandwidth analysis across diverse frequencies and systems.
Advanced noise reduction and precision: Delivering capabilities such as residual EVM measurements that are crucial for validating next-gen mobile communication standards.
Modular, software-defined flexibility: Features like CrossACT firmware demonstrate the company’s investment in integrated test workflows and multi-domain synchronization, improving measurement efficiency and accuracy.
By embedding Linux as its operating system, the instrument also supports long-term security and operational stability, a key requirement in defense and other high-reliability sectors.
Customer Benefits: Solving Complex RF Challenges
The FSWX enables users to:
Reduce test complexity and time by performing synchronized measurements across multiple channels.
Unlock deep analysis of interference and signal interactions, improving reliability in applications from satellite systems to autonomous vehicles.
Achieve unmatched EVM accuracy with cross-correlation, revealing imperfections that conventional analyzers miss — crucial for ensuring quality in 5G, 6G, and emerging modulation schemes.
Streamline operations with a secure and future-ready platform supporting firmware upgrades, modular configurations, and user-friendly interfaces.
For companies and institutions building tomorrow’s wireless and radar solutions, the FSWX represents a future-proof investment, turning complex measurement scenarios into routine tasks.
Looking Ahead
Rohde & Schwarz will debut the FSWX at the IEEE MTT-S International Microwave Symposium (IMS) from June 17–19, 2025, in San Francisco, offering hands-on demonstrations to RF innovators.
