In the image below I want to make a sweep on the load resistance at port 2 and see the voltage across it (in the image below it has a 303 value and named R25). Based on the fact that the characteristic impedance of port 2 affects the z-parameters, I want to know what I should put for the port impedance of port 2. Should it be equal to the load resistance?&lt;\/p&gt;&lt;p&gt;Also I would appreciate any recommendations on how I should approach accurately reading the voltage across the load resistance in HFSS.&nbsp;I am sweeping for a wide range of resistances from 1 Ohm to 100kOhms.
