Rohde & Schwarz Strengthens Automotive Network Test Portfolio with New ASA-ML Compliant Solution

Asymmetric network technologies like ASA are becoming increasingly important as in-vehicle sensor data grows. Meanwhile, ensuring interoperability in an expanding multi-vendor environment is becoming more difficult. Rohde & Schwarz enables standard-compliant testing, efficient device debugging, and reliable in-vehicle communication with its new ASA Motion Link compliant test solution for R&S RTP oscilloscopes. The Automotive SerDes Alliance (ASA) was founded in 2019 to provide a multi-vendor open standard for high-speed asymmetric SerDes (Serializer/Deserializer) technology. This technology is optimized for data transfer from high-resolution cameras, LiDAR, and radar sensors to ECUs, and for continuous data stream transmission from ECUs to ultra-wide high-resolution displays. At the same time, it ensures that high-speed data transfer does not interfere with other in-vehicle electronics. With a bandwidth of up to 16 Gbps/lane, it provides the scalable 'nervous system' required for Level 3 autonomous driving and beyond. As a long-standing member of ASA, Rohde & Schwarz actively participates in various technical committees and contributes to the development of open standards. The new R&S SPLUS-K105 option, available for R&S ScopeSuite+ software, provides comprehensive electrical compliance testing for the latest ASA Motion Link standards. This software fully controls and automates the high-performance R&S RTP oscilloscope, allowing each test case to be easily executed via a web-based GUI and step-by-step wizard. It supports all test cases related to each speed grade, from SG1 to SG5. Furthermore, it can control the R&S ZNB3000 vector network analyzer and other compatible VNAs to perform high-precision return loss measurements. By combining oscilloscopes, vector network analyzers, and compliance software, it achieves high-precision and reproducible measurements essential for signal integrity analysis, time-domain impedance analysis, and PHY, ECU, cable, and connector verification, supporting reliable in-vehicle communication.
