Introduction: Vehicle integration and multiplexing has created new challenges for module level EMC testing. Many modules today require some form of network communication for normal operation and to prevent the setting of fault codes. The current OEM EMC test specifications do not adequately cover how to set up the "network load box" now required for modules with network communication needs. Many questions come up at this point. Should the network load box be totally isolated or grounded? Should the power connections be taped to the ground plane or spaced above? How/where should the network be terminated? How should the CAN settings in the network load box be configured? If my CAN controller is outside the chamber what are the critical delay limits before arbitration will no longer be reliable? I would like to offer up my ideas on the above subjects, show some experiments and hopefully generate some good discussion on this very important issue.
