      This is currently not possible. I’ve never thought about such a task. Indeed it would make sense. But several things (like “apply optimized values to the circuit”) would not work then.

        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!

          Again, you are absolutely right. I have just uploaded the corrected files. Thanks for you reports!

            Yes, you are absolutely right! I will change it.

              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.

                  This is a nice idea indeed! So it’s on the todo list now.

                    Indeed, the plan for future versions is

                    * zoom with mouse wheel
                    * move with right mouse button pressed
                    * context menu with right mouse button click

                    As 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 ohms

                      This 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?

                              Yes, you’re right. Thanks for the report! It will be fixed in the next release.

                                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”.
