C63.4 (Test Method for the Measurement of Radiated Emissions)

C63.4 is a standardized test method used to measure electromagnetic emissions radiated from electronic devices. It involves placing the device in a controlled environment and using specialized equipment to detect and quantify electromagnetic signals that escape into the surrounding space. The goal is to ensure the device meets regulatory limits for electromagnetic compatibility, preventing interference with other electronic devices and ensuring safe operation. This testing helps manufacturers confirm their products are compliant with standards set by authorities governing electromagnetic emissions.
