Measure line impedance in CST microwave studio

Hey,

I am working with CST microwave studio since a few days. My goal is to perform a impedance transformation from 50 Ohm to 2 Ohm. Is there a possibility to measure the line impedance at a certain position?

Best regards,

CST have optenni software to do impedance transformation designs. but im not very familiar with that. you can look for online videos on that..
