Harmonic Port and PSS with HB engine

Hi,

I read in the manual that the Harmonic Port option of the PORT component is available for harmonic balance large-signal analyses only:

For reasons I cannot yet understand, however, I am not able to make my (very ideal, maybe that's the reason) circuit to work properly with HB.

I have no issues with PSS-shooting though, so after much troubleshooting, I just decided to use that.

I just checked that PSS with HB engine works OK-ish

My end goal is to perform an AC sweep on top of the nonlinear simulation, either PAC or HBAC, so overall I guess my questions are:

- Does the harmonic port option work for PSS with HB engine? 

- I read "HB large-signal analysis" so better ask: is this port option working for small signal analysis like HBAC and - in case - PAC?

Thanks!

Michele
