Smith Chart Impedance Measurement With NanoVNA

[@wb7ond]

There are two other methods of measuring impedance. The method shown in this video is most accurate around the 50 ohm point (S11). Putting the component in series between Port 0 and Port 1 is used for higher values of impedance, and the shunt, whereby the Port 0 and Port 1 are connected straight thru, and the component is connected from that straight thru to ground. Mostly used for less then 50 ohms... W0QE has an excellent video on this very subject. "Three methods to measure impedance with the NanoVNA".. Thanks for the video

Hi Bruce, thanks for that. It was very helpful. Please can I ask where you got that SMA component tester PCB.

That is actually a board I made for testing ceramic filters, just adapted for testing components. I will head over to PCBWay and see if I can make it public for you. It includes a calibration jumper

I am only seeing my last five orders - this board was earlier. Hopefully they get back with me about converting this board to public.
