EMC testing covers many different standards, among which the most commonly used standard is formulated by the European Electronics Industry Association (EEA) and is called the European Union EMC Directive Standard. In addition, FCC regulations promulgated by the Federal Communications Commission are also important standards for EMC testing. In addition, different countries and regions also have their own EMC testing standards, so the specific testing standards need to be determined according to different regions and uses.
What are the steps and processes of EMC testing?
Electromagnetic compatibility testing needs to be carried out in a professional laboratory, which is mainly divided into three steps: first, prepare the test equipment, put the equipment to be tested into the test environment, including connecting it to the analytical instrument with special test equipment. Secondly, the experiment was carried out. When testing, it is necessary to simulate various common electromagnetic fields and phenomena, and carry out corresponding tests according to the types and uses of equipment. Finally, the test results are analyzed and evaluated. By analyzing the test results, whether the electronic equipment meets the relevant EMC standards is evaluated. When the result does not meet the standard, the problem is located and retested or corrected as necessary.
