With the social, scientific and technological progress, the radio technology has been widely used in various fields. However, due to the extensive use of radio equipment, transmission equipment, uneven quality, plus some wireless users illegally set to change the technical parameters of the equipment transmitter transmitter aerial electromagnetic environment is becoming increasingly complex electromagnetic environment pollution, radio interference events have occurred, and to maintain the good order of the airwaves, and to ensure that legitimate radio services to carry out normal, timely detection of radio equipment on a regular basis, it is necessary to restrict the use of substandard equipment. Especially in the field of communication, mobile communication technology in recent years, the rapid development of 2G and 3G mobile communication technology use into the tens of thousands of households, with the increasingly wide coverage of mobile communication network, the number of mobile communication base station increasing The base station transmitter RF detection work more and more important. The one hand, the wireless channel is filled with a variety of electromagnetic waves by RF detection can detect whether the transmitter emission indicators in line with national standards, troubleshoot radio interference generated from the source, normal development of to protect legitimate mobile communications business; another many indicators of the aspects in the communication device with noise, interference, are directly related through the detection to the base station RF, it is possible to troubleshoot the cause dropped calls due to the deterioration of the RF index, poor quality of communication voice, is not turned ON, blind and other failures, and to ensure that the quality of communication . Domestic public mobile communication is now a second-generation and third-generation mobile communications system, generation systems including GSM, CDMA, three-generation systems, including TD-SCDMA, WCDMA, CDMA2000. China RF parameters for different systems to develop the technical standards as the basis of the RF detection. With the rapid development of mobile communication technology, the microwave power tester, spectrum analyzer, vector signal analyzer functionality is also innovation field use the Anritsu MS8609A comprehensive test system for GSM, CDMA base station transmitter instance RF detection test equipment and test principle, analysis discusses modern mobile communication transmitter RF detection methods, and summarizes some of the concerns of the analysis and testing, and finally, introduce a new test technology and test equipment function and development trends. Closely combined with the actual work of the author, to provide a reference for mobile communication base station RF testing experience.
