Use NanoVNA-App https://github.com/DiSlord/NanoVNA-App

Now there is a GREAT suggestion for the Nanovna, add a firmware update option to the PC Saver program!! This way we have an “all in one” application to use and manage the nano. -- Regards, Chris

Strange, yes, but personally I prefer it that way, so that you know exactly what is being added to your computer rather than a massive install.exe with no idea what it contains! 73, David GM8ARV --

Did you check it with an ohmmeter? BTW, I noticed in the first picture that you're using/reading S21. Is that correct? And "Transform" was set to "OFF". (but maybe you changed that after taking the

Hello Thank you for the link. It's strange that we have to download file by file. It's done, thank you 73 -- F1AMM Fran?ois De la part de David J Taylor mercredi 21 juin 2023 12:39

The Nano's TDR function can show 'defect' location - even multiple "feature" locations. It shows distance in meters. You move the cursor to the "odd spot" in the trace, and read the distance to there.

Fran?ois, Gyula has already pointed you to the group (thanks). The newer and more capable TinySA Ultra has a "4-inch" screen which is adequate (for me) for many things, but there is a TinySA program

Hi Doug Do NOT cut the wire just fold it back at the insulator and tape it in place. Cheers John G4FRD --- New Outlook Express and Windows Live Mail replacement - get it here:

Don, My preference would be for the developer's effort (for which we are all extremely grateful!) to go into improving the VNA functions, especially as there are spectrum analysers in the NanoVNA

Only thing missing is distance to problem in meters or feet. You have to quess the Er.

Yes, I suppose I do, no pin so open(no contact). Lesson learned! Thank you again, Muggs KC3UDZ

A true TDR sends out a short pulse and looks at the time it takes for that pulse to return. The NANO VNA sweeps frequency and notes where the frequency when reflected impedance approaches Infinity and

"..cost beyond the software development." does not imply that software is free, on the contrary, it explicitly recognizes that cost. Even a "bad and slow" SA function is better than nothing if there

It's a wonderful, very useful feature. Very quick and easy to use, no other settings to make. It does use a different method than TDR, and is explained in the info for the first firmware version that

The tinySA group can be found here: /g/tinysa/topics -- Gyula HA3HZ ( http://ha3hz.hu )

Why do you think software development is free? However, adding a spectrum analyzer function to NanoVna is not a good idea, it will be a bad and slow analyzer with a lot of limitations.

Hello I have never used this kind of small spectrum analyzer TinySA - I read that there are at least 2 software on PC (like nanoVNA-saver) which allow to connect the small box TinySA. I don't want to

Let's go back to basics and use only the basic behavior of an open and shorted 1/4-wavelength of coax (in the cable, not physical length: SHORTED END measures as an open OPEN END measures as a short
