According to the definition of IEC, EMC (Electromagnetic Compatibility) is "the ability of an equipment or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment." Operating electronic products can interact with each other by means of conduction, induction and radiation, thereby under certain circumstances it may disturb, interfere or even harm equipment and people nearby. Therefore most electronic products have to perform EMC tests to ensure safety. STCs EMC testing facilities, which include open area test site, semi-anechoic chamber, shielded room and TEM cell, enable us to provide EMC testing service to many electronic products.
