One way to avoid the mess would be to concatenate all the circles into one array and plot that as a single graph. Of course that would be a fairly large array but Labview can handle that much easier than trying to graph several discrete circles.
That's very nice, would be great,
Thank You !
Concerning the stability graphs in the VNAs, as far as I know, Rohde Schwartz analyzers have them as an option (but only K, mu1 & mu2 plots).
I've believe that Keysigh have this option for VNA, too, as far as I have seen it's description in Joel,'s textbook.
Which low cost VNA are you using that has support for 2-ports? Depending on the specs, it may be worth porting the software to it.
I have Jan's open source VNA, it's a fairly new project,
the USB protocol they had implemented is still a subject to minor changes as the SW is still under development.
As we had discussed previously, this work is still in progress, and it is not properly documented yet.
