NanovnaF-V2 cable fault TDR function is very useful for finding problems in coax.

No video shows this great function of the nanovna so i shot this clip to show how it can be selected and what it can do.
Found several mysterious faults in cables, quite a unique function!
There is a very good video about the tdr usage;

Hope you like this special use of the nano, thanks for watching.

It can be set up to actually show you the impedance of an unknown piece of coaxial cable. I use it to sort my 10 ohm, 12 ohm and 17 ohm cables. I even found that some cable I removed in an industrial setting was 93 ohm. A great instrument. I have several, just yesterday I received the liteVNA64 and it rocks.

Thanks John, yes, there are several ways to confirm/discover impedance.
Was just so impressed with the horizontal line representing the transmission
line and what happens along it, to my surprise the cursor also indicates the impedance in green anywhere along the trans line.
Have had experience with tek high end tdr ( unaffordable ) but this is fine for the work i am doing with it, cool for finding moisture in connectors up a pole, totally takes all the guesswork out of it.
Glad you liked it, Thanks
