With the development of electrical and electronics technology, becoming increasingly prevalent in household electrical appliances and electronic, radio and television, post and telecommunications communication and computer network increasingly developed, increasingly complex electromagnetic environment and deterioration, the electromagnetic compatibility of electrical and electronics products (EMC, EMI electromagnetic interference and electromagnetic resistance EMS) problem is increasingly attention by governments and enterprises.In order to standardize the electromagnetic compatibility of electronic products, all developed countries and some developing countries have developed emc standards.The domestic many electronic products manufacturer attaches great importance to the EMC certification, EMC design, from product development stage so as to greatly improve the qualified rate of EMC test, not delay the normal listed products.To get your product to go public and capture global markets, start with EMC certification standards.

    What is EMC testing?

    EMC test also known as electromagnetic compatibility (EMC), is refers to the electronic product size on electromagnetic interference (EMI) and the anti-jamming ability of comprehensive evaluation of (EMS), is one of the most important indicators of product quality, electromagnetic compatibility measurement is composed of test site and test instrument.The purpose of EMC testing is to detect the effects of electromagnetic radiation generated by electrical products on human body, public power grid and other electrical products.

    There are different kinds of terminology in EMC:

    ·EMC emission test - a test for electromagnetic interference caused by electrical equipment (EMI)

    ·EMC test - a susceptibility to electromagnetic interference from other sources.

    · electrostatic discharge (ESD) - static electricity emitted when two objects are in contact.ESD includes the static electricity you feel when you are drying clothes in a dryer or a lightening bolt.

    · conduction immunity test - inject current into a system input and output line during test.

    · conduction radiometric test - radio-frequency energy from an electrical device to the electrical system.

    · intentional radioactive body - a product intended to generate and emit radio frequency energy, such as a radio device that resembles a mobile phone

    , has no intention of radiator - a device is not intended to emit radio frequency energy, but the radio frequency used for its spontaneous or by connecting to the device sends a radio signal device, such as personal computers or television sets

    · radio frequency - a frequency of electromagnetic energy emitted for communication.

    , radio frequency compatibility - antenna connection in the system operation of the radio frequency receiver or transmitter subsystem, can run normally, not due to antenna connected to the antenna performance ability
