VNA E5071C偏置三通不成功

我从未在ENA上使用偏置T恤，但是在许多其他网络分析仪上。
偏置三通只是射频端口的直流馈电，所以你需要的只是直流电缆，一边是BNC连接器，另一边是香蕉电源。
对于ENA我不太确定，但内部偏置三通的最大电流可能不应高于500mA。
Bias Tees持续连接，因此无需软件。
如果你记得来自ENA的DC偏见，那就是不同的故事。
这意味着您从ENA采购供应。
在ENA的前面，如果我是正确的话，它们是一些提供5V的概率连接（从不使用它，只需播种几次，就像安捷伦人使用它来启动一些演示板一样）。
您还可以使用辅助直流输入来测量设备电压或电流（使用已知电阻和某些数学运算的电压差）。
这将适用于扫描（频率，功率，时间......）

  I never used Bias tees on ENA, however on many other network analyzers.
The bias tee is just DC feed in the RF port, so what you need just DC cable probably with BNC connector on one side and banana on other side to power supply.
I am not sure of that for ENA, but max current on internal Bias tees probably should  not be higher than 500mA.
The Bias Tees are continuously connected so no software required.
 
If you have in mind DC bias from ENA that different story. That will mean that you sourcing the supply from ENA. In the front of the ENA  they are some prob connection that provide 5V if I am correct ( never use that, just sow couple time like Agilent guys use that to power up some demo boards).

You can also use auxiliary DC input to measure the device voltage or current (using voltage differential over know resistance and some math). That will work over sweep (frequency, power, time ...)
