全部

1·Most are powered by the DC voltage from the LNB.

大部分是采用LNB的直流电压。

2·The RF satellite test probe allows direct measurement at the LNB output or at the satellite receiver or cable TV.

卫星射频测试探头允许直接测量lnb输出或卫星接收器或有线电视。

3·The experimental results show that the bi-fuzzy controller is much better than the conventional PID controller, and can meet the design requirements for the LNB temperature controller.

实验结果表明了该系统的控制效果优于常规pid控制器，满足LNB控制系统温度控制要求。
