请问如何实现已经捕获的现有s1p数据文件的相位偏移

每个数据点？
我只是在“度”栏中添加“90”吗？
>>简短回答是肯定的;
这就是offeset的作用，将所有角度改变相同的量。
这有点不常见。
更常见的是改变电延迟，这意味着相位随频率而增加。
这就是你用模拟线得到的，它在中心频率为90度（假设中心频率为1/4波长）。

Short answer is yes; that is what phase offeset does, change all angles by the same amount.

This is somewhat uncommon.  A more common thing to do is to change the electrical delay, which means that the phase change increases with frequency.  That is what you get with a simulated line, where it is 90 degrees at the center freq (assuming a 1/4 wave length at the center freq).

非常好 - 谢谢乔尔博士。
是的，我认为lambda / 4电气延迟就足够了，但是，正如我后来所知，你只能在延迟真正为90度的一个频率上旋转90度。
在测量谐振器并且想要获得对未调节的短位置的s1p响应的情况下，所有点需要被相等地旋转，因此不使用VNA上的电延迟，而是使用相位偏移。
谢谢你的澄清 - 我现在有了一个脚本，可以帮助我正确地转换所有的s1p跟踪，一切都很顺利。

  Excellent - thanks Dr Joel.

Yes, I thought that a lambda/4 electrical delay would suffice but, as I later realised, you only rotate by 90 degrees for the one frequency where the delay truly is 90 degrees. In the case of measuring a resonator and wanting to get the s1p response to the untuned short position, all points need to be equally rotated and hence electrical delay on the VNA is not used but phase offset is used instead. 

Thanks for the clarification - I've now got a script together that will help me transform all of my s1p traces correctly and all is well.
