EN 300 328 v1.8.1标准功率测试方法研究

欧盟2012年6月发布了EN 300 328 v1.8.1标准,并于2015年1月1日强制执行,为了解决标准中提及到跳频和宽带调制蓝牙及无线局域网产品的多天线功率,搭建了新的功率测试系统.根据对测试流程和各设备技术参数的分析,多通道功率系统由高速率采样功率计探头、开关箱、信号综测仪以及软件控制电脑等设备构成,通过对现有产品测试验证,搭建后的系统符合EN 300328 v1.8.1标准要求.新测试系统的提出,解决了现有蓝牙和无线局域网产品多天线功率无法正确测试的问题,同时也为第三方测试实验室提供了除了选择国外测试系统外的解决方案.

Power Testing Method for EN 300 328 v1.8.1 Standard

In June 2012, European Union released EN 300 328 vl. 8.1 standard for frequency hopping and wide-band Wireless LAN products. It is referred to multiple antenna output power testing adopted on January 1,2015. In order to solve the multi-antenna power testing issues from the blue tooth and WLAN products with frequency hop and broad band modulation, a new multi-channel power measurement system is built. With the analysis of testing procedure and equipment parameters, It is found that the system is constructed with a high-rate sampling power sensor, a switch box, a signal tester, a computer, and other devices. To pass the test and verify of current products, the built system can satisfy the requirements of EN 300 328 vl. 8.1 standard. The proposed system can solve the problem, that is,the multi-antenna power of existing Bluetooth and wireless LAN products cannot be properly tested. Meanwhile, besides the foreign products,it provides a testing choice for the third-party laboratory.
