Re: TDR Measurement with NanoVNA Saver #nanovna-saver #tdr


 

Not sure why you created a rtf file for the screenshot, the result is poor
quality, the details are unreadable.

I've been checking my coax using NanaVNA Saver 0.2.2-1 on a NanoVNA-H with
Hugen 0.4.5-4-g96e7efe firmware.

I have a piece of 75 ohm Commscope F-11 coax going to a junction box in
the yard, I believe thet the far end is open.

I ran the TDR function. The Estimated cable length 41.104m (134ft 10.3in)
seems correct but I don't understand why I get this stair step graph with
reflections at multiples of the 41.1m length.

I've attached a screenshot named TDR Commscope F-11 in the files section.
