Probing question
Do you have a probe that can plug into a VNA and test/record the impedance of traces on a PCB? One with very small tips on one end and an “SMA” connector, “APC” connector, “N” connector, or even a “BNC” connector?

A VNA is capable, but using 2 measurements, short and open. See this article:

A TDR is a more direct measurement, using our J2154A and an oscilloscope:
