【摘要】：RF性能是手机终端性能的重要组成部分,近几年来,随着互联网快速发展,手机终端各项性能快速提升,手机的频段不断的增加,从原先的单单2G到目前的全网通,手机校准的时间也大大增加,如何又快、又准确地对手机RF性能进行快速有效测试成为各大厂商急需要解决的重要问题。而传统的测试方法既不能满足日益增长的测试需要,又存在测试工作效率低、错误率高的问题。本文详细分析手机终端射频校准程序,针对目前手机校准方法中存在的问题,设计并实现了手机射频校准测试系统。本课题讲述校准的方法和概念,并在程序的优势与不足的基础上,介绍了本文所涉及的关键技术知识。并且详细分析手机射频校准需求,设计相应的校准程序及系统数据库,以自动功率控制(APC),自动增益控制(AGC),自动频偏控制(AFC)校准为主要软件需求,在此基础上建立手机终端射频校准系统;搭建Windows下的手机自动化测试环境,应用RS CMU200和AG66319B等设备,实现射频参数的校准和下载,并对校准过程中的数据和结果进行数据库备份与还原,最后应用本文设计的校准系统进行总结,并对测试结果进行分析。本文设计实现的手机自动化校准程序表明,所提出的校准方案,可以极大提高校准工作效率和准确性,同时降低校准误测率。
[Abstract]:RF performance is an important part of the mobile phone terminal performance. In recent years, with the rapid development of the Internet, the mobile phone terminal performance has been rapidly improved, and the frequency band of the mobile phone has been continuously increased, from the original 2G alone to the current full Netcom. The time of mobile phone calibration is also greatly increased. How to quickly and accurately test the RF performance of mobile phone has become an urgent and important problem to be solved by major manufacturers. However, the traditional testing methods can not meet the increasing needs of testing, but also have the problems of low efficiency and high error rate. In this paper, the radio frequency calibration program of mobile phone terminal is analyzed in detail. Aiming at the problems existing in the current method of mobile phone calibration, a radio frequency calibration testing system for mobile phone is designed and implemented. This paper describes the methods and concepts of calibration, and introduces the key technical knowledge involved in this paper on the basis of the advantages and disadvantages of the program. The requirement of RF calibration of mobile phone is analyzed in detail, and the corresponding calibration program and system database are designed. The main software requirements are automatic power control (APC), automatic gain control (AGC), automatic frequency offset control (AFC) calibration. On this basis, the radio frequency calibration system of mobile terminal is established, and the automatic testing environment of mobile phone under Windows is built. The calibration and download of RF parameters are realized by using RS CMU200 and AG66319B, etc. The data and results in the calibration process are backed up and restored by database. Finally, the calibration system designed in this paper is used to summarize and analyze the test results. The automatic calibration program of mobile phone designed in this paper shows that the proposed calibration scheme can greatly improve the efficiency and accuracy of calibration and reduce the rate of calibration error.
