That’s true! This is not a realistic example at all, but just a demo.
If anyone can share a real-life example here, this would be great!
Sorry, this is not yet supported, but on top of the todo list. For small lists, the if() statement could be used, but it’s very tedious.
Hm, seems to be a Linux problem. Sorry, I don’t know about a workaround. I think this can only be avoided internally by a different drawing method.
Indeed, the plan for future versions is
* zoom with mouse wheel
* move with right mouse button pressed
* context menu with right mouse button clickAs far as I know this is what most programs do.
The correct usage of z-parameter transformation is:
Z_param = stoz() if your s-parameter ports have 50 ohms
Z_param = stoz(25) if your s-parameter ports have 25 ohmsThis works in equation components only, not in diagram equation.
Anyway, if you want to know the loading of the source, stoz() is not the correct function, because z-parameters are defined with open port terminations.
rtoz(…) does the job (see attached picture).
Hello,
You’re right, complex port impedances are not supported. A warning would be nice here.
But the Touchstone file component supports the necessary transformation, if the property “func” is set to “complexZ0”. For frequency-independent port impedances, the s1p-file needs two lines only. See example in the picture.

Yes, you’re right. This is still on the ToDo list, because it’s more complicated. I think it will not be fixed before version 5.
The s4p files contains data up to 2.4 GHz, your simulation runs up to 24 GHz. I guess this is not what you wanted?
Would be great if you can share the project (snp-files plus schematics) that shows the problem. Using QucsStudio package file would be best, of course.
Many thanks!
Thanks a lot for the example! I can reproduce the bug and will fix it.
Workaround: Open the subcircuit schematic before the simulation starts, i.e. select the subcircuit component and press “CTRL+i”.
