Measuring impedance in PCB trace

[suleymancskn]

Hi Fedevel Academy Family!

I want to measure impedance on PCB trace.
How can we measure the impedance on the path in a pcb that we have physically?
I have a VNA. Is it possible with this?
Does anyone know how to measure practically?

It's about TDR, but you will get the idea.

I am not sure about VNA, I have "create a video about VNA" on my todo list. I know there are some videos on Youtube using VNA and measuring impedance, but I have not tried that by myself, but maybe someone may share their experience?

Hello, I learned from a different person that I can measure with a milliohmmeter or microohmmeter.

I will report the results related to this.

I am designing a CPW line. I don't know if I can calculate the series resistance, coil and parallel capacitance values of this line. Can anyone assist with this?
