Model-based systems engineering (MBSE) transforms traditional design by utilizing domain models to integrate requirements, architecture, behavior, and verification into a cohesive digital framework. This methodology advances the "digital twin" concept, allowing complex physical system engineering activities to be conducted virtually, which is invaluable when physical testing is costly or impractical. Keysight’s PathWave System Design software is instrumental in this process, helping engineers bridge the accuracy gap between design models and real-world performance. By providing advanced simulation and analysis tools, Keysight software enables precise virtual validation, ensuring that digital twins accurately reflect physical RF systems throughout the entire development lifecycle.
