Making EMI Compliance Measurements
This Keysight application note details the process of performing Electromagnetic Compatibility (EMC) compliance measurements for electronic equipment. It outlines the four primary types of tests – radiated and conducted emissions & immunity – focusing on emissions testing within the 9 kHz to 40 GHz frequency range as dictated by standards like FCC Part 15 and European Norms (EN). The document emphasizes correctly identifying applicable regulations based on product type (ITE, ISM, automotive) and intended market. It details essential equipment requirements including a CISPR 16-1-1 compliant EMI receiver (like the Keysight N9038A or N9048B), bandwidths (from 200Hz to 1MHz depending on frequency), and the importance of using Line Impedance Stabilization Networks (LISNs) for accurate conducted emissions measurements.
