Resistance measurements with RADTP signals

Hi there!

I’m currently trying to measure the resistance/impedance between the RADTP signals and the ground (GND), but I keep encountering the following error: "resistance invalid, out of range".

Below are the different code approaches I’ve tried so far. If you could help me figure out what I might be doing wrong or suggest alternative commands to achieve this, it would be greatly appreciated. Thank you in advance for your assistance!

Code 1:

Code 2:

Code 3:

If there are alternative commands or additional configurations required to make this work, I’d love to hear your suggestions.

Thanks again for your help!
