Method for Derivation and Synthesis of Conducted Susceptibility Limits for System-Level EMC

This paper presents a novel method for the derivation of conducted susceptibility requirement limits for roll up and synthesis into an overall system-level design. If a system-level EMC design is an assemblage of compliant subsystems, then the subsystems should be an assemblage of compliant components or module designs. This approach requires tailoring the system-level requirements through to component- or module-level designs. The method discussed is applicable to a variety of components and implementable early in the design process. The method provides rationale for the derivation limits, while maintaining traceability to system-level requirements. A discussion is included on comparison and margin analysis of input filtering for verifying compliance to conducted susceptibility requirements at the system level. Detailed examples using both commercial and military requirements are included.
