安捷伦N9340B®索外部干扰源使用说明1、首先用安捷伦仪器专用连接线连接定向天线〔天线建议最好使用八木天线〕和安捷伦测试仪的INPUT接口。

2、按安捷伦测试仪的电源开关，开机后按仪表右边面板上的“F2 〔起始频率〕〞按钮，右侧数字面板输入850MHZ在按“ F3 〔终止频率〕〞按钮，右侧数字面板按数字输入970MHZ.3、按显示屏幕下面的“ AMPTD按钮，按F3按钮〔把“预放〞设置成“开〞状态〕，再按F6按钮〔把“高灵敏度〞设置成“开〞状态〕同时还要设置参考电平，建议设置为-40db。

形成图像如下所示：图像中有两个显著波峰的是电信C网使用的下行频点，图像右侧是移动的频点。

我们测是否对我们的频点产生干扰主要是看对图像右侧的波形的幅度变化时否很大，看右侧的图像的电平值是否整体都有提升，如下列图：如果出现如红色线所示的整体抬升的如果出现如上图所示的红色波形，就是外部干扰源。

找到了外部干扰源后，可以拿起手中的八木天线，有指向性的来找干扰源，当你指向的某个方向出现的波形抬升最明显时，就是干扰源的方向。

PS: C网的下行频段和移动G网上行频段有重叠局部，因此G网的上行容易受到C网的下行影响。

但是这种干扰不是外部干扰源，不会引起整个波形的整体抬升。
