Asymmetric network technologies such as ASA are becoming more important for transporting the increasing volume of sensor data in vehicles. At the same time, interoperability is harder to secure in a growing multi-vendor ecosystem. Rohde & Schwarz addresses this with a new ASA Motion Link compliance solution for the R&S RTP oscilloscope that focuses on standards-compliant testing, enables efficient device debugging, and ensures compatibility and seamless automotive communication.
The Automotive SerDes Alliance (ASA) was formed in 2019 with the ambition of providing an open standard for a multi-vendor ecosystem for high-speed asymmetric SerDes (Serializer/Deserializer) technology. It is perfectly optimal to carry data from high-resolution cameras, LiDAR, or radar sensors to the ECU or provide continuous data streams from the ECU to ultra-wide, high-definition displays, all the while ensuring that high-speed data transfers do not interfere with other sensitive vehicle electronics. With bandwidth capabilities scaling up to 16 Gbps per lane, it provides the scalable “nervous system” required for level 3 autonomous driving and beyond.
Rohde & Schwarz has been a long-standing member of the Alliance, contributing to the various technical committees to help further the open standard. The new R&S SPLUS-K105 option available on the R&S ScopeSuite+ software offers comprehensive electrical compliance testing for the latest ASA Motion Link standard. The software fully controls and automates the R&S RTP high-performance oscilloscope, allowing test engineers to seek guidance effortlessly through each test case via the step-by-step wizard and the web-based GUI. All relevant test cases for each speed grade (SG1 to SG5) are getting support from the software. In addition, users can also control the R&SZNB3000 and other supported VNAs for performing accurate return loss measurements.
The combination of oscilloscope, VNA, and compliance software provides capabilities for signal integrity analysis. The time domain impedance analysis in repeatable measurements is essential for verifying PHYs, ECUs, cables, and connectors, fostering reliable Automotive communication.
