New to nano VNA ... just got the latest and greatest. I've used port extensions with my higher end Tek VNA and my "miniVNA tiny". I successfully applied port extension with the "VNA View" software

I am on another forum where we have created topic posts, and those posts are only links to message threads about that topic. Anyone can add to the topic post thread. For example, here we might have

Hi to all I note, with disappointment, that many members start new discussions on topics already covered in previous discussions. Why not post messages to those threads instead of creating new ones?

Tom, Thank you for taking the time to make your post. In particular I noted the following: - The calculated inductance of your 4.7 uH inductor varied from 4.56 to 4.82 uH _(+2.5 to -3%) over a wide

Great project and information! Many thanks, Tom! Dave, KE9ED

Very interesting. Thank you for sharing :-) -- VE6WGM

Greetings All, As L/C component value measurement appears to be a present topic of interest here I decided throw my 2 cents in by posting a couple of tables that show the measurements results from

Sorry to hijack the thread. I think Rich intended to send a private email response to me, so we’ll take the conversation there :-) -- VE6WGM

Thanks for the honest thoughts Rich :-) This kind of critical examination really helps a person to think about ways to improve one’s presentation. I’ll have to go back and listen to myself at

Great vid. Around 8m30, you are trying to hit +1j, and can't, and mumble something about accuracy...but I think the issue is that the steps in the sweep don't hit exactly that point. here I think

YES :) Sometimes fingers faster then brain

When I turn on Transform, the x-axis doesn't change to time until I tap the screen. Then when I turn it off, the time axis remains displayed.

NanoVNA will only measure at the points to the display and skip all intermediate frequencies so you must be sure to match your frequency span with the number of measurement points and the bandwidth of

These videos I made were intended to be used to measure and verify the nominal values of inductors and capacitors, but it might help you to come up with something that works for your purpose.

Amazing work! Thanks for sharing Tom! -- VE6WGM

Good work Roger! I spoke with Brian on the phone myself a while back and he was able to very clearly and succinctly convey his thoughts on this matter. I concur with your writings here fully :-) Thank

Hi Roger, Attached is a photo of my tweezers and calibration reference box which is similar to a photo within the article. Yes I have found the tweezers to be surprisingly precise if used in

There has been considerable discussion lately on how to measure resistors, inductors and capacitors using the NanoVNA. In particular measurement errors of these components seems to be a topic of
