QUCS: how to add port with complex impedance? Now using 50Ohm "power source" element.

I want to add some kind of element, that can simulate complex impedance. I tried to edit "power source" impedance to complex one, but error occurs "unexpected complex number".

Oh, i found the solution here: https://sourceforge.net/p/qucs/discussion/311050/thread/e005519d/
and also there is some auto-post added by anonymous automatically, copied my message from this board (is it some new fashionable technology?)

But here is new problem arises: how i can measure impedance somewhere in scheme, only using Ohms law and AC simulation? Any chance in S-simulation mode?
