In the dissertation, the test of EMC, for the products of AMOI Electronic Corporation Limited specially GSM mobile phone, will be discussed. It mainly focuses on the test site (anechoic chamber and shield room), EMC regulation of international and civil (relating to the products of AMOI), the theory of EMC compatibility, tester (manual power net and EMI receiver), what's more , will study the EMC test method about the GSM mobile phone of AMOI company.Electromagnetic Compatibility (EMC) is a science , which is used to study the compatibility of electrical and electronic devices and systems within the common electromagnetic environment without a degradation of performance. It is obvious to gain the perfect result, two request will be thought, one side, It descends the level of electromagnetism disturbance, the disturbance which is brought by the equipment, will be under the limited point. On the other hand, It need to improve the capacity of immunity to a disturbance. For the moment, with the increasing number of electrical and electronic products entering the market, all equipments almost perform on the environment full of electromagnetic disturbance. In order to assure the equipments operate within the common place without disturbing each other, It is only way to attain that every product must pass the test base on the same EMC standards.With the developing of the communication technology , the system of digital beehive communication is applied widely, but the problem caused by EMC is becoming more and more serious. Base on practical application of civil communication, aim to EMC test of GSM systems and assistant instruments, bring forward by Telecom Academe, Calibration center of Information Industry Department drafted out the standards of GSM & CDMA, it issue to implement by Information Industry Dept, mobile phone, which only already passed the request of this standard, can be sold in China. At the same time, the products of information technique were forced to obey the CCC attestation. For the products, EMC standard make them sure the quality when they enter the market. |
