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 multivendor 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, 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 optimised to carry data from high-resolution cameras, LiDAR or radar sensors to ECU or providing uninterrupted 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 16Gbps 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 be guided effortlessly through each test case via the step-by-step wizard and the webbased GUI. All relevant test cases for each speed grades (SG1 to SG5) are supported by the software. In addition, users can also control the R&S ZNB3000 and other supported VNAs, for performing accurate return loss measurements.
The combination of oscilloscope, VNA and compliance software provides capabilities for signal integrity analysis, time domain impedance analysis and accurate and repeatable measurements essential for verifying PHYs, ECUs, cables and connectors fostering reliable Automotive communication.
