The eye diagram is an analysis method for evaluating the signal quality of transmission networks with a moderate to high transmission speed. CAN networks can transmit information bit by bit from sender to partly distant receivers. The information transfer can, however, be easily corrupted by the network topology, cable length between the participants, line and terminating resistors as well as external electric influences. Both eye diagram analysis and serial bit mask analysis allow these influences to be identified and corrected early during the configuration phase of the CAN network.
