摘要
本系统是用于电磁场与天线课程实验的一个室外辐射性实验系统 ,该系统巧妙地运用了彩色电视机的电子调谐器来构成测量接收放大器 ,改进原有的实验系统。该系统可使天线辐射功率降低至13d Bm ,且工作稳定可靠 ,体积小巧 ,代替原有的实验系统 。
This system is designed for an outdoor radiation experiment in the electro magnetic theory and antenna course.It contains an improved measurement receiver amplifer, which is craftily made out of the electronic tuner for color TVs.It reduces the radiation power of the antenna to 13dbm, which therefore greatly reduces the influence of the radiation on the researchers conducting the experiment.Moreover, compared to the old system,this system is inexpensive but very stable,and occupies a small working space.
