动态准确度图需要帮助阅读

嗨，我正在使用VNA不确定性excel工具来瞥见我正在使用的VNA的不确定性。
这是N5245A选件400 VNA。
使用N4691B ECAL。
我无法理解为什么动态精度图中有多行。
这看起来有点像Pout / Pin图，他们在大学时使用它来显示1dB压缩点。
但为什么有多条线？
每条线是否代表校准时的功率水平？
我附上了我正在看的图表。
如果你能给我一个如何阅读这个图表的简短细分，我将非常感激。
而且，我已经看过Joel博士的书和其他资源，试图找出来，我只是不确定。
谢谢，KTB

Hi,

I'm using the VNA uncertainty excel tool to get a glimpse of the uncertainty of the VNA I'm using. It's the N5245A Op tion 400 VNA. Using N4691B ECAL. I'm having trouble understanding why there are multiple lines in the dynamic accuracy graph. This seems sort of like a Pout/Pin graph that they used in college to show 1dB compression points. But why are there multiple lines? Does each line represent the power level at calibration? I've attached the graph I'm looking at. If you could give me a short simple breakdown of how to read this graph I would greatly appreciate it. And fyi, I've looked in Dr. Joel's book and other resource to try and figure it out and I'm just not sure.

Thanks,
KTB
