Electromagnetic compatibility emc test refers to the equipment or system in its electromagnetic environment can work normally, and does not constitute an intolerable electromagnetic nuisance ability to anything in the environment.EMC is mainly composed of electromagnetic interference EMI and electromagnetic sensitivity EMS. Electromagnetic interference EMI refers to the electromagnetic interference caused by the degradation of the performance of the equipment or system. Electromagnetic susceptibility EMC is the immunity of the equipment to the presence of electromagnetic interference in the environment.
EMC testing is mainly to confirm that the normal operation of the equipment in the process of electromagnetic interference in the environment can not exceed a certain limit, and the equipment has a certain degree of immunity to electromagnetic interference in the environment.
