我现在用MCC128接入信号发生器产生的正弦波信号，通过网页测试程序查看采样后的数据，发现仅在一个通道上数据信号，采样出来好几个通道都采集到了同频同相位数据，但是幅值不同，如果在两个通道上分别施加正弦波和三角波，从数据采集后的波形看会出现相互干扰，两通道信号同频率干扰弱一点，不同频率的话基本上完全失真，请问在MCC128的输入通道信号接入上有什么特殊要求吗？我现在是把信号发生器的同轴电缆芯线接到AI端子CH1H，同轴线的屏蔽端接到AGND

您好，我现在打算用MCC118读取三相电压数据并观察波形，想用示例程序中的连续采样和浏览器看图范例，但是在按照https://shumeipai.nxez.com/2018/10/18/get-started-with-the-evaluation-for-mcc-118.html中的要求，安装执行：pip install -Iv dash==0.30.0 dash-renderer==0.15.0 dash-html-components==0.13.2 dash-core-components==0.38.0
后，运行Server.py一直提示错误，信息如下：

还望各位大神给解读一下问题出在哪？如何解决，谢谢！
