Evaluation of high-speed digital media for automotive cabling
Digital systems in automotive applications are becoming more and more prevalent. Multiple cameras may be streaming video data to the vehicle 'head-end' controller. Radar or lidar systems feed rivers of data at high speed to the central processor for collision avoidance and navigation. Arranging for all of this data to arrive at the head-end controller with minimal corruption in the presence of a great number of interfering signals is a challenge. As a first step, a VNA may be used to set expectations for signal integrity over any chosen digital transport media.
