I want to use my NanoVNA to determine if the cables I use in my lab are good enough, like the correct Z, no sharp bends or crushed dielectric or bad connectors, and so on.
My first vague idea was to
1. Calibrate solt for a plane at the end of a short cable.
2. Connect the cable under test, the CUT, to the end of the short cable in 1.
3. Connect something, (short, open, load?) at the end of the CUT.
And then know what a perfect CUT with Zc= the load test R would look like on the NanoVNA display.
And that I don't know.
Can you advice on this?
