卫星接收机解调门限的测试方法

The demodulating margin testing method of satellite receivers

接收机解调动态门限在卫星系统设计中是一个很重要的参数 ,虽然接收机一般给出其值 ,但如何用简易方法测出接收机实际解调动态门限电平对于指导设计和系统维护更具有实际价值 .

The receiver demodulating dynamic margin is a very important parameter in designing a sound (receiving) system. Although the receiver provides the demodulating margin, it is still valuable for designing or maintaining the system if we can take easier methods to test the voltage. This article supplys the practical method.
