I thought you are supposed to calibrate each specific frequency (range) test for better accuracy. Only one calibration for all frequency testing is much easier.
You calibrated the vna, then changed the freq range. The vna takes the calibrated range sample points, and extrapolates it to the new range. You might end up with only 1 or two points of sampling over the entire new range.
Здравствуйте ! Вы не подскажите как настроить что бы при прокрутке можно было встать точно на нужную частоту ,а то у меня перепрыгивает мне надо 145.300 ,а курсор или 142.800 и следующий сразу 146.600
Did you use JUST 1 patch cable and connect to BOTH ports, OR, 2 separate cables that were supplied? Having to receive this device without a manual, how to setup, how to calibrate this seemingly simple device in disguise is frustrating especially if you have a different version like the H4, with a different screen. Geez. To be honest, I'm goings around in circles just to get the SWR ONLY.
Think mine came with just 1 patch cable and one open load and short connection I just used 1 patch cable . Not used it in a few years been using my sark100

Perfect! Not to long and to the point.
Thanks for this. Hits the spot!
Nice and simple explanation Jez. 👍😉
Great explanation mate. Thank you
no worries hope it helped
Nice one,
you should have an amazon link on where to buy,
Just have to duff copies/broken that are on ebay

At 2:44 (the thru step) you connected both terminals of a single cable correct?
Yes thats what i did
@@2j4ezgot it. thank you!
You must calibrate over the frequency that you going to use, not calibrate then choose the frequency range.

Can you please help me I want to find the resonate frequency using the NanoVNA-H4 any help I'll appreciate it

You kinda goofed it. I suggest you watch a few nanovna UA-cam videos as to why.
