距离小于１０ｍｍ），这样能减少反射并能确保耦合到的噪声为共模噪声；（B）使差分线对的长度相互匹配以减少信号扭曲，防止引起信号间的相位差而导致电磁辐射；（C）不要仅仅依赖自动布线功能，而应仔细修改以实现差分阻抗匹配并实现差分线的隔离

动态范围就是能分辨强信号，如基波信号和弱小信号，如噪声谱的关系，时间精度就是能分辨瞬态谱，因为被调制后不同的时间谱是不同的，这个好的频谱分析仪的优势普通diy太难了，主要是工艺问题，如电路板的微带线设计，阻抗匹配

实际电流互感器我在这里用了磁环套在槽路上来实现同时要经过阻抗变换电路实际制作过程中发现反馈信号输入到Pin2 Pin6 内阻抗非常重要就算是Kohm级别都会影响到电路的正常工作在这里大家就要想办法做一个阻抗匹配啦
