1、Practical Use: You can use the analyser to debug the duplexer, test the standing wave impedance of the antenna, the insertion loss of filter, isolation, standing wave, attenuated cable and shorten coefficient, phase, and the amplification of the antenna amplifier. 2、Frequency Meter: Improved frequency measurement can measure antenna frequencies from 2.4G to 3G. 70dB (50KHz-1.5GHz), 60dB (1.5GHz-3GHz). Reflection measurement S11, 50dB(50KHz-1.5GHz), 40dB(1.5GHz-3GHz); antenna analyser, 1.005(50KHz-1.5GHz), 1.02(1.5GHz-3GHz). 3、Improve Accuracy: The vector antenna analyser is equipped with an upgraded shell, which has strong anti interference and improved accuracy. Equipped with a 3.2in touch screen and touch screen pen, it is more accurate and easier to operate. 4、Safe Working: Powered by battery or USB, the built in 2000mAh battery can work continuously for about 3 hours, if extra working time is needed, you can connect an external mobile power supply or power supply. 5、Broad Utility: The performance is greatly improved. Can be controlled by PC, compatible with for Linux, for Windows (7+).
