Making Precompliance Conducted and Radiated Emissions Measurements with Option EMC for the X-Series Signal Analyzers (CXA/EXA/MXA/PXA)
This Keysight Technologies application note details a precompliance EMI testing methodology using the X-Series Signal Analyzers (CXA/EXA/MXA/PXA) with Option EMC. It contrasts precompliance with full compliance testing, highlighting cost benefits of early-stage identification of potential electromagnetic compatibility issues before formal certification. The document focuses on both conducted emissions (9 kHz to 30 MHz) and radiated emissions (30 MHz to 1 GHz - expandable depending on device clock frequency) measurements, outlining preparation procedures like LISN use, antenna setup, ambient signal measurement, and data evaluation techniques. It also covers troubleshooting diagnostics and references relevant standards such as CISPR 16-1-1 and FCC Part 15 for various product classifications (ITE, ISM).
