Upcoming car generations will be equipped with a growing number with intelligent driver assistance systems, complex multimedia components and systems for autonomous driving. In order to reduce the duration and the amount of test runs but at the same time acomplish all the test requirements of all departments, the benefits of an intelligent and powerful data logger like the GL5300 series come into effect. These data logger series cover the synchronous recording of CAN/LIN bus systems, from FlexRay networks to CAN FD busses (up to 4x CAN FD on the GL5350 and up to 12x CAN FD on the GL5370) and Ethernet networks. These complex, networked technologies provide ever-increasing amounts of data that make the troubleshooting aspect during the development phase more extensive and complex.
