A new solution changes how engineers test in-car data links, making signal validation simpler, faster, and more reliable.
Rohde & Schwarz has expanded its automotive in-vehicle network testing portfolio with a new compliance solution for ASA Motion Link (ASA-ML), aimed at improving how engineers validate high-speed SerDes links used in advanced driver assistance systems and autonomous vehicles.
The R&S SPLUS-K105 option in the ScopeSuite+ software platform is designed for test and validation engineers working in automotive semiconductor companies, ECU and sensor manufacturers, Tier 1 suppliers, and compliance labs. These users can use it to verify that ASA-ML-based designs meet electrical compliance requirements across all speed grades (SG1–SG5), reducing integration risks in multi-vendor vehicle architectures.
In practice, the tool automates ASA-ML compliance testing on the R&S RTP oscilloscope, guiding users through structured test sequences via a step-by-step workflow and web-based interface. Engineers can use it to debug signal issues, validate PHY layer behavior, and ensure consistent performance across components such as cameras, radar, LiDAR modules, ECUs, cables, and connectors.
The workflow can be extended with vector network analyzer measurements using instruments like the R&S ZNB3000, enabling precise return loss and impedance characterization. This combination allows users to analyze signal integrity in both time and frequency domains, making it easier to identify mismatches, reflections, and degradation in high-speed links.
At a system level, the solution helps engineers ensure reliable high-bandwidth data transport in vehicles, where ASA-based asymmetric SerDes links carry data from sensors to ECUs and from ECUs to high-resolution displays without interfering with other in-vehicle electronics. With bandwidths reaching up to 16 Gbps per lane, ASA is increasingly used as the backbone for next-generation automotive networks supporting Level 3 and beyond autonomy.
