Gregory's Serveranother way is to calibrate to the end of the SMA cable and use the "electrical delay" setting. this didnt work well for me. I'm used to larger, more professional VNAs that let you adjust it with a knob and watch the Smith chart in real time. the NanoVNA makes you play a game of Guess-The-Number...

 @Darius yes it might actually be good enough to do it that way. i'll have to experiment some more. |
@tubetime you should be able to measure the electrical length with the far end open (or shorted) by measuring the phase and halving it. Would be nice if the tool could do it for you though! I have some QoL ideas like this I keep meaning to try implementing in my nanoVNA after using it at work a bit
