Roger, Can You evolve how that is done. I have never seen that possibility with NanoVNA-App. Regards/Torbjorn

How do you measure a coax with my nanovna

Once you have calibrated you setup at the measurement plane including any fixtures, the following may help you (I've got the VNA in front of me as I write so I'll go through the steps). To measure

Hi Stan, I gratefully will accept your kind offer of help. Thank you and I am not in a hurry. zapel406@...

Hi Dean and everyone who gave an answer firstly thank you. Yes I am using Nano Saver on my laptop, yes I am aware of how to calibrate and the importance of measuring at the plane, yes I have made jigs

Phil, Even if you know how to use the VNA, measuring the QMX lowpass filters is tricky. I have done it a few times and can help you, but it would have to wait until Monday since I currently have

I second this! After you learn to properly calibrate the VNA in your test environment, look up YouTube videos on the Smith Chart, there are many. The chart will map resistance, inductance, and

Use Smith Chart. If your marker is in the upper half, it's inductive. If below, it's capacitance. Sent from AT&T Yahoo Mail on Android On Sat, Apr 19, 2025 at 7:46 AM, Jon via

Dean, Can you kindly explain the method you have used to measure inductance and capacitance with NanoVNA? 73 Jon, VU2JO [email protected]> wrote:

Phil, Are you using Nano VNASaver software on your computer to connect to the NanoVNA or are you trying to do it directly? First thing to remember is, Calibrate at the connection you are using to

Though I have been using NanoVNA for a few weeks now, I was not aware that it can be used for measuring inductance and capacitance. Now I will also join your search! Currently I use my LCR meter to

Hi Everyone, I'm new to the VNA and trying to measure both inductance and capacitance but getting stupid results. Is there someone who has this version of the VNA could walk me through the setup and

Yes, that is the reference choke...

Is this the reference to what you are trying to do? https://www.dj0ip.de/open-wire-fed-ant/balanced-line-choke/

Hi The choc of john its exactly an 1/1 balun made by a lot of ferrites, measuring a balun with an NanoVNA on a chack its a thing and results of balun mounted with a dipole antenna was a different

I think this is not correct in this case, Nizar. Measuring the choke is not measuring a transmission line with specific characteristic impedance that needs matched; it is more like measuring an

I wouldn't really describe this as a "common mode" (although that is used) - it's really better conceptualized as a third wire which is connected to the feedpoint, as Roger said. As noted, the choke

Users of a Maxwell or W2DU choke need to be aware that the effectiveness in reducing common mode current is not directly related to the magnitude of the impedance |Z| or S21 loss that they measure

I had bought one off ebay and it arrived in the smallest possible box, and when I took it out of the box that switch was at a rather odd angle, and did nothing. I returned that one, no issues with

Hi S11 Smith measurements or S11 IZI is also possible , it should have higher then 1500 Ohm as mentionned by the paper , no care with one wire or two wire connected together , it should be
