Thanks Herb. That will help a lot with my understanding.

Hello Herb,
thank you for answering this! :-) You're absolutely right.
The impedance steps are only shown in one direction, though: Going up. I've
yet to figure out quite *why*, but I am looking into it.

In the TDR display there are two traces, One Red and one blue. I
understand the red but not the blue. Would some please give me an
explanation of the blue trace?
===========================================================================
You can think of the red trace as equivalent to selecting
<DISPLAY-TRANSFORM-LOW PASS IMPULSE> on the NanoVNA. Where the peaks are
indicative of time and distance.
The blue trace can be thought of as being equivalent to selecting
<DISPLAY-TRANSFORM-LOW PASS STEP> on the NanoVNA. Where levels are
indicative of impedance variations (see attachment).
