Hi,
I have been trying to use the portAdapter from the rfExamples lib to sweep my load impedance. I run into issues there. Please check the image below : 
For gamme=0.6, and phase=90deg, the output log shows that I have neg resistance at the portAdapter. I would like to understand what is going wrong.
These are the Properties form of all the instances.
Since I encountered issues with the portAdapter and since portAdapter is really not necessary for HB simulations, I thought I will try the Loadpull option within the HB analysis setup form.
So my schematic looks like the following : 
In this scenario when I run the simulation and look at the output log, I dnt see any negative resistance issues. 
Can someone please help me on what's going on?
Many thanks in advance.
Regards,
Amit
