In June 2012, European Union released EN 300 328 v1.8.1 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 v1.8.1 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. ©, 2014, Journal of Nanjing Institute of Posts and Telecommunications. All right reserved.
