Re: vna ~ nanovna : (r,x) comparative results but no comments


you're needs to setup electronic delay compensation in the NanoVNA to eliminate that curve. it happens because your load connected with different transmission line length than calibration kit load.

For example, here is 500 Ohm load measured with NanoVNA. First picture is how it looks with no electronic delay compensation. And the second picture is how it looks with electronic delay compensation 242 picoseconds entered into NanoVNA. (242 ps = 15 mm connector)

NanoVNA software which allows to see series and parallel RLC charts, can be found here:;t=4881
