Rohde & Schwarz strengthens its automotive network testing portfolio with new ASA-ML compliant test solutions

Asymmetric network technologies like ASA are becoming increasingly important as automotive sensor data grows. However, ensuring interoperability in a expanding multi-vendor environment is becoming more challenging. Rohde & Schwarz’s new ASA Motion Link compliant test solution for R&S RTP oscilloscopes enables standards-compliant testing, efficient device debugging, and reliable automotive communication.

The Automotive SerDes Alliance (ASA) was established in 2019 with the aim of providing 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 ultrawide 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 the 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 with the 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, and each test case can be easily executed through 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.
