The nano can measure inductance all by itself, too. Or, at least give you the impedance at the frequency you are measuring with. And the recent -H firmware versions have a specific "find resonance"

Thank you very much for your explanations. 1/ We found in old spectrum analyzers for RADAR (1960) delay lines made of a coaxial cable with losses. Our teacher had told us that it allowed to have a

It's hard to measure an assembled trap (or measure self resonance of a coil) with traditional 1 or 2 port fixtures, because the fixture is part of the system. I suppose you could develop some

Thanks,, Mike. -- Bob AF9W

I am measuring traps in a bandpass filter in circuit for tuning the filter. I have created some pickup coils that "sort of" work but I am looking for an improved solution. I'm using the Nanovna to

Can you measure just the area where the spike is. I have had odd readings when the scale has been too coarse, and have missed some retails..

Equivalent circuit=Spice model is not same as impedance. VNA gives you impedance, Coil64 and https://www.g3ynh.info/zdocs/magnetics/part_1.html give you equivalent circuit. Or an approximation of

I hope this is not a silly question, but where do you need GDO, if you have a VNA? That is, you can measure coils and capacitors with VNA. Measuring resonance frequency is bit harder, because Q gets

Hi Bob If you look at /g/nanovna-users/message/33324 you will see a picture of a pickup coil I made. It's 5 turns of 0.9mm enamelled copper wire on a 20mm diameter PVC former. This

Telecommunications engineers who work with transmission lines (telephone cable pairs) that exhibit complex characteristic impedances (Zo) generally use return loss and reflection loss to characterize

There have been references to pickup coils to use the Nanovna as a GDO. Since I have zero experience with a GDO and have a need to measure some inductors, could someone provide some specifics on

Using a smith chart VNA with a manual antenna will be an eye opening experience. You will never want to go back to the hunt and peck method of the three controls. Lester B Veenstra K1YCM M?YCM

Steven, [Transceiver], [Tuner], [Antenna] = [Nano], [Tuner], [Antenna] Set up if you wish to use your tuner to "adjust" your antenna resonant point with your Nano. David Reed, ac0yw

Hello all, I would like to connect my NanoVNA, antenna and manual tuner (MFJ-969). I can connect the nano and antenna but am not sure how to bring in the tuner. An example of what I am trying to do

I moved the coil away until the frequency of the dip remained steady then moved a bit further. The vertical scale is 0.01dB/div so the dip is perhaps not as large as it seems. -- Mike?

Pedro, You write "I have a nanoVNA S-A-A-2 which is useless because it doesn't measure Rs orXs independently in S21 mode, only measures impedance complex." Recent firmwares from DisLord provide what

Looking better but you still have a large dip. Keep moving further apart until you can barely see it and record the dip frequency as you go. Roger

I'd think somewhere between 18.082620 and 18.085096, because that's where the imaginary part goes through zero.

Roger I made a new sending coil and it works a lot better now. -- Mike

Roger always has good ideas. Attached is the measurement (via nanovna-saver) of a trape and I will then explain to you how the measurement is made. When I read S11 Return loss I say it resonates at
