I managed to get the hang with it, and carried on with the next few demo practices. The key thing to make it look similar to what the board is showing was, to manipulate with the frequency settings, b

It happens in certain selections in the menu. I cannot recall which selection it was now. I will make note of that, and update here next time when it happens. But it sounds like it is not some serious

Set it to LOGMAG. Freq. range was 1 - 100 Mhz.

I can tell it was wrong setting. It is showing resistance? I should have set it for LOGMAG? Will try again later.

This is what I got.

The menu display containing k M G is cut off. It happens in certain occasions, not all the time. Is this faulty? Or is it because something else?

Do you set the frequency range say from 20 Mhz to 50 Mhz, and set the centre frequency to 30 Mhz, and then sweep the frequency to get the graph? What about SPAN and RBW (band width) - what do you set

I received the RF Demo kit for NanoVNA. The cables are indeed fiddly to attach on the pcb board, but I am getting used to it. Just hope that it will last for some long time rather than get mangled, an

I see RE Demo Kit for NanoVNA-F for demonstration. Would it also work for the H4? Is this a good kit for NanoVNA beginners for learning? Does it have any practical use than educational? I also read a

Good point as well.

Yeah, I think my set allows 6 or 7 setting savings, and can recall them I remember in the menu. It seems a great idea. Putting on the tiny Open Short Load bits unto the SMA port and taking them out ca

Great info & advice. Thanks.

Does it need new calibration every time when different frequency range is selected? Or is it enough just one initial full freq. calibration?
