The new SAE J1816 for measurements of narrowband electromagnetic emissions from land vehicles

The Society of Automotive Engineers (SAE) procedure J1816 `Performance Levels and Methods of Measurement of Electromagnetic Radiation from Vehicles and Devices, Narrowband, 10 kHz to 1000 MHz´ is summarized in total and the essential parts of the measurement methods and limits are described specifically. Its contents are listed, and the reasoning behind the methods is explained. The performance levels (limits) of J1816 are compared to those of J551, ANSI C63.12, and the US Federal Communications Commission. Part 15J, Class B limits. Both near-field data reduction of magnetic-field strengths and the rejection of broadband noise while measuring the narrowband vehicular emissions are discussed
