Electromagnetic compatibility testing (EMC testing) ensures that electronic devices operate correctly without causing or being affected by electromagnetic interference. This testing evaluates how well a device can function in its intended environment while meeting regulatory standards. It involves measuring emissions and immunity to interference from other devices. The process typically includes various tests, such as radiated emissions, conducted emissions, and electromagnetic susceptibility. These tests help manufacturers identify potential issues early in the design phase, ensuring that their products comply with safety and performance standards before reaching the market.
