Hi James , the nanovna H H4 and LiteVNA64 , whith the recent FW
has the TDR function but named TRANSFORM .
You can reach the relative menu , tapping the DISPLAY >> TRANSFORM >> TRANSFORM ON.
In the pictures , the 270mm cable connected to CH0 .

The NanoVNA-F-V2 has a convenient TDR function: It has its own menu choice. Just requires settings dependent on cable speed factor and short/long cable. Quite intuitive. Firmware 0.5.4 handles everything correctly. Nice, big display. I like mine.

I know the NanoVNA H4 has a TDR function because I've used it. It isn't
called that in the menu and is a little tricky to figure out. There is a
Youtube'video that describes its setup. Also message 12494 in this group.
