Nizar, please post the .s2p file. I'd like to see whether the Y21 method offers any improvement over the S21 method for your test. Brian

Hi Roger Thanks for all this papers and sharts, here my simple direct measurements comparaison of this morning for the same balun 1/1 commun mode impedances done by two differents methods : 1) S11

Hi Rod, Confession - I'm not a software guy. It does look like an issue with PIP/python rather than nanovna-saver. Google tells me it is likely the libssl-dev was not installed when python was built.

Hi Paul, when installing nanovna-saver 0.7.3 from github I get the error shown here: a Thank you again for helping me. I love the software. Cheers,? Rod

Hi Paul, Thank you, installing via apt JustWorks! I am using it an it's great! I had been attempting an install from? github. Later this weekend I will send feedback to you with screenshots on how I

Hi Rod, Did you have trouble installing it, or you install it and it doesn't run? I have mint mate (i.e. not cinnamon). I can't recall if it is 22 or 22.1. ?All I did was 'sudo apt install

All: In my recently emailed out method of measuring inductors and capacitors using the Smith Chart presentation on the NANOVNAs, I seriously also considered treating accuracy and determination of SRF.

Below are plots of a 3K SMD resistor and a 1 ohm resistor. Also a 10 pF capacitor which shows good results over a wide reactance range. Note that you need a good test jig and this becomes critical

Comments by Jean-Roger, Nizar and others concerning accuracy of S11 shunt measurements inspired me to write this post. The accuracy of any measurement is important and an excellent paper on this

Hello, Using Mint22.1 All attempts to install NVNAsaver have failed B/C ssl problems, including the instructions at

"Because in case one is measuring a reactive component at a frequency range of interest, which coincidentally is around the self resonant frequency." On the silver mica new unit the leads are about

Hi Nizar, Be careful with this NanoVNA accuracy sheet. It remains indicative, and as you say, accuracy remains dependent from hardware bridge and calibration load. The initial purpose of this picture

Hi Jean Your NanoVNA accuracy Shart is Very Nice : imposed naturaly by the S11 NanoVNA hardware 50 Ohm bridge , indeed S11 accuracy is better around 50 Ohm bridge resistor : S11 accurate prety good 3%

Thank you Dave. It is a quite interesting overview. I just suggest to add an advice about having also an eye of the jX (reactance) value. The idea is to check that this value combined with R (Z

I just implemented a simple method to freeze the automatic scaling. While the numbers are the same, this capacitance comparison is much more compelling. Brian

Thanks for all the information and suggestions. I will chose a low cost option and have learned to be more thoughtful and careful with this wonderful tool. I have learned a lot from it and have a

It was the H4 . Purchased from R&L. I accept the blame for the damage. The nano was not defective.

Here's an example of what the Y21 method can do. The plots are for an ATC 2.7 pF capacitor. The VNA was an HP 8722D with Inter-Continental test fixture and calibration kit. Self-resonance is about 9.4

There is also a large family of low-capacitance limiter diodes from a number of (non-Chinese) sources designed specifically for the purpose if you choose to build your own. They are readily available

As Dave mentioned limiters like mini-circuits VLM-33W-2W-S+ are a good solution. Unfortunately these are hard to get as they are being re-designed, and ebay sellers know this and have jacked up prices
