Abstract
The present disclosure provides an apparatus and method for measuring echo responses of communication links used in in-vehicle networks with high resolution and high dynamic range, allowing for diagnostics of various failures and/or degradations with high precision. Additional information can be provided to indicate signaling quality, insertion loss, and return loss of the communication links used in in-vehicle networks. Together, these measures and information can provide a comprehensive diagnostic capability that improves network reliability and safety of in-vehicle networks.
