After some thought, the plan is to add onto the 2-Port Plot tab.
That's would be OK, thank You.
Though I am unfamiliar with Unilateral factor.
Does it have the same definition as the mu-factor mentioned in the .pdf paper above?
In fact, most modern VNAs have this stability analysis option built-in.
At my previous job I had access to all these tools, but unfortunately, now I've been fired out, so now I am just in a process of setting up my home lab, where I cannot afford any expensive equipment.
For me it's just a hobby now, nothing more.
I shall post here some images with stability analysis graphs, but not too soon.
What's might be interesting to see in the SW features is the ability to plot a family of load stability circles on one graph simultaneously in case of broadband stability analysis, for implemented frequency sweep, as it is shown in the last section of L. Besser paper
Thanks,
Alex
