The role of systems EMC analysis in large system EMC management by equipment EMC assurance

Electromagnetic compatibility (EMC) at the system level is often ignored, to the detriment of total system performance. Complete systems EMC is often a difficult and elusive goal, since systems are often too large to adequately or efficiently test, or complete systems are not available for test until initial customer installation, where testing could be impractical. Following a review of definitions of system EMC, an approach to systems EMC analysis is described. The interpretation of analytical results is discussed. Key to the management of a systems EMC approach is the management of subsystem component EMC on an individual component basis as a prerequisite to system EMC.<
