Jim Lux,
I got a break from TDR by seeing "Swan Lake" , enjoyed the music , not sure about the ballet.
My XYL comment was "woman body legs are not attached to the body..."

BTW the antenna "mast" fell in recent windstorm, dummy forgot to add hose clamp to the first cammo pol;e and it broke .
No damage to anything, just pride.

I found a short piece of same, labelled RG6 cable so I can compare it with the unlabeled one.

I need to go back to grammar school and study Fourier to make sense of all of this.

I still believe the nanoVNASaver has an issue with using the "sweep" entries...
Also the "TDR" and the TDR display options do not match - the "POP up sub menu in particular.

PS
During my college study there was a joke going around with one of the professors pet question
"draw me a graph..."... if you forgot to add dimensions to either axis you have failed the exam.
TDR graph is missing the "y axis" dimension.
