FlexRay physical layer eye-diagram mask testing

What is FlexRay?
An automotive network communications protocol under development by the FlexRay Consortium. It is considered better than CAN and MOST both in terms of performance and price. Its key features are: 10Mbps data rate, time-triggered behaviour, redundancy, safety, and fault-tolerance. The core member companies of the FlexRay Consortium are BMW, Bosch, DaimlerChrysler, Freescale, GM, Philips and Volkswagen.

What is physical layer?
The Physical Layer is the first level in the seven-layer OSI model of computer networking. It translates communications requests from the Data Link Layer into hardware-specific operations to effect transmission or reception of electronic signals. The implementation of this layer is often termed PHY.
