我最近买了一个类似的VNA（E5071B 4端口），我正在使用N4431B 60006 Ecal模块。
虽然我多年来一直在使用这些分析仪，但这是我第一次尝试使用端口扩展功能，而不是在PE菜单中添加延迟时间。
我最初尝试在PE菜单中使用损耗补偿时，在测试LF到几GHz的小值电容时会产生非常混乱的结果。
我没有得到我期望的ESR配置文件，我认为我正在使用此功能。
所以现在我已经回到在RF模拟器中添加端口扩展，因为我可以生成我最常用的端口扩展的相当准确的2端口模型。
还有一个夹具补偿菜单，我打算在某些时候进行探索，看起来它可以在分析仪本身内实现同样的东西。但是目前我有点懒，并且正在进行PE / de嵌入
模拟器。

I've recently bought a similar VNA (E5071B 4 port) and I'm using the N4431B 60006 Ecal module. Although I've been using these analysers for many years at work this is the first time I've tried to use the port extension feature beyond adding a delay time in the PE menu.
My initial attempts to use the loss compensation in the PE menu have produced very confusing results when testing small value capacitors across LF through to a few GHz. I don't get the ESR profile I expect and I think I'm using this feature incorrectly. So for now I've gone back to adding the port extension in an RF simulator as I can produce a fairly accurate 2 port model of the port extension that I most commonly use.
There is also a fixture compensation menu that I intend to explore at some point that looks like it can achieve the same thing within the analyser itself.. But at the moment I'm being a bit lazy and doing the PE/de embedding in a simulator.
