The intelligent and connected car is no longer a futuristic concept. With each new model launched, leading automobile manufacturers are pushing out increasingly sophisticated navigation, safety and infotainment features. The excitement over autonomous driving is spurring safety developments, with needs for superb sensor systems that can over-ride bad driver decisions or actions. Other technologies, like vehicular biometry and new connected infotainment gadgets are rapidly changing the dashboards of future cars. On a broader level, innovations like route tracking and driver health monitoring are set to trigger a need for connectivity to supporting infrastructures by government agencies. Imagine road gantries that monitor how frequently you use busy roads, or automatic carbon-emission report systems, leading to taxation systems based on how eco-friendly your car and your driving habits are. These are exciting times for automotive electronics manufacturers, and one can see the parallel of Moore’s Law moving onboard the vehicle – only this time, besides transistors, we are talking 5G technology, 802.11ac WiFi, BroadR-Reach, MOST150, CAN, LIN, FlexRay and more. Applying advanced automotive technologies offers enormous benefits; however, it also triggers new design and test challenges for developers and manufacturers. Based on over 75 years’ experience and technical knowledge of RF, millimeter wave, wireless, and high-speed digital design and test, Keysight Technologies, Inc. provides one of the broadest and most powerful range of automotive design and test solutions from early R&D to manufacturing stages, backed by our team of dedicated technology experts worldwide. Like you, we believe every drive should be maximized for safety, smoothness, and style for every driver and passenger.
Testing and Characterizing Automotive Serial Buses
With significantly increasing electronic features and functions, today’s automobiles include a variety of serial buses such as I2C, SPI, UART, CAN, CAN FD, CXPI, SENT, LIN, FlexRay, BroadR-Reach, and MOST. Automotive serial buses must be able to operate reliably in the harsh electrical environment of the automobile where random and infrequent transients occur. Keysight Automotive Serial Bus solutions solve challenges of designing and testing your auto-motive serial buses.
Physical layer testing
The primary measurement tools used to test and characterize the physical layer of these buses are oscilloscopes, such as Keysight’s InfiniiVision X-Series and…
