摘要
为了克服手动微波测试教学系统测试过程繁琐的问题,给出了一种新型的微波测试教学系统,在原手动微波测试教学系统的基础上,用步进电机驱动测量线,用微机进行控制,实现电压驻波比、反射系数、波长、阻抗的自动测量以及沿线驻波分布图形的显示。该系统的使用简化了微波参数的测试过程,提高了测试效率和数据的准确度,增强了系统的测试功能。
A new kind of microwave measuring teaching system is introduced in this paper in order to overcome the fuzzy measuring process of manual microwave measuring teaching system. It is based on manual microwave measuring teaching system, droved by a stepping-motor and controlled by a computer. Microwave parameters such as voltage-standing-ratio, reflected coefficient and impedance can be measured automatically, and the voltage standing graph along the measuring line is displayed. The measuring process of microwave parameters becomes easy, the measuring efficiency is improved, and the function of microwave measuring system is increased.
