How to use NanoVNA Saver software

How to use NanoVNA Saver software connected to NanoVNA V2 for testing LorA Helium filters, attenuators and amplifiers.
Thanks and credits Zarath Holger Müller
You may download the software here : github.com/NanoVNA-Saver/nano...

I am a subscriber! Just under a couple other usernames! Thanks for setting this up. Looking forward to the rest of the video.

I had done all the same steps as you to calibrate First calibrate only port 0 on the device and then via the software When I sweep, I don't see a line connecting the dots. Instead it looks like a scatter plot graph. I'll try again as you describe step by step to confirm, but maybe my nano has an issue.

Thanks for support Dimitrios!

How can we check the NFC tag parameters using nano VNA.

[@viocaia]

Got no idea if it's possible, likely a spectrum analyzer will be better if any radio waves involved

Hmmm I've just downloaded from github and got a different software for nano vna saver. It started with a black background, 4 windows, and the setup is totally different. Can't find any videos on how to change the windows ( functions of the sweep) so unable to do the SWR sweep I wanted... Can't use the software because I'm, unable to change the modes. It looks like a better software, but is harder to operate... I'll post the version later.. Can you do a video on this latest version please..

[@viocaia]

I recall I did a resoft to earlier model, didn't work well, the touch screen frozen and so...there should be a software to push the firmware in USB mode to NanoVna.

mister do you have LCD for roland EM2000 ?? im from indonesia 🙏🙏

[@viocaia]

Sorry I don't..

[@najeebqureshi6409]

sir can you make a video to measure LC resonant frequency.

[@viocaia]

I'll do..

I'm having a very hard time seeing the text on your screen. I don't expect you to redo this on my account but perhaps on future videos, you can zoom in. At 3:24, you go from calibrate and "at first you should see the cable itself". What test is that ? I can't read it from the screen, sorry. My default screen is a Smith Chart on top and polar below. I'm just wanting to check my home brew antennas for resonance. I'm getting some new glasses in a couple of days. See if that helps but every text is a blur on the screen. Curious to know what others are experiencing.

It means a cable connected from port 0 to 1 directly..if the cable and connectors are ok you should see a straight line...change your display settings from left down corner...''display" and choose what you need..probably for antenna tuning is channel 0 SWR and Return loose..means two dsplays..but no Smith..

don't forget to like and subscribe..thanks!

@@viocaia Thanks, I found that SWR selection but don't see any sort of run test command anywhere. I tried SWEEP but it returned an error: Cannot configure port. Time for bed. thanks.

[@viocaia]

@@SmeeUncleJoe Strange..I'll redo the steps..

[@SmeeUncleJoe]

@@viocaia It would be great if you could do a video on checking antenna resonance. I suspect it's the most common motive for people buying the NANO. Certainly in my Ham Radio circles.

[@SmeeUncleJoe]

During calibration, why did you ignore the direction to put a load on Port 1 ? You said you "don't have it" but you just used it on Port 0 . I don't understand.

[@viocaia]

Do exactly like I said ...don't attach any load to port 1..just aconnect the cable between 0 and 1

[@zktec1]

I have the same question. Why was the load not attached to port 1 as the dialog stated...

What nanovna recomand ?

[@viocaia]

I'm not sure..lots of fakes ..you can find originals here... nanovna.com/
