EMC Pre-Compliance Fundamentals
This whitepaper details the importance of Electromagnetic Compatibility (EMC) pre-compliance testing during electronic product development. It explains how conducting internal EMI tests—both radiated and conducted emissions/immunity—can significantly reduce costs and delays associated with formal compliance certification against standards like CISPR, FCC, and EN series. The paper outlines four primary EMC test types, emphasizing that approximately 90% of testing should occur during prototyping and pilot runs rather than solely at the final compliance stage. Keysight Technologies’ equipment, including the N9010B/N9020B signal analyzers, N6141EM0E X-Series Measurement Application, and N9311X close-field probe set are presented as solutions for performing pre-compliance tests.
