载波通信单元测试技术研究

Study on the test technology for the carrier communication unit

程控衰减法是对电力线的载波强电信号进行上位机程控式衰减的一种方法。本文推导出基于程控衰减法的程控衰减器电路实现,研究了通过程控衰减器测试载波通信单元灵敏度的方法,总结出测试载波通信单元灵敏度的步骤。最后通过案例分析,验证了该方法的可操作性和有效性。

The program controlled attenuating method was used to control the carrier electrical signal on the transmission lines. In this paper, the program attenuating circuit has been derived, the test of carrier communication unit sensitivity through program controlled attenuating devices has been studied, and the test step for carrier communication unit sensitivity have been concluded. At last, the feasibility and efficiency of this method was verified.
