make sure you're running 0.0.12 - the version number should be in the title bar. The "Calibration assistant" button is what you're after: [image: image.png] -- Rune / 5Q5R On Fri, 27 Sep 2019 at 16:36, Nick <g3vnc@...> wrote:

Re: nanovna Battery Specifications
BTW..... this version is the so-called "better" one with shielding. It is better construction than my "white salamander worst" unit or my black "worse" one. The noise floor might be slightly lower on this one but I find no practical measurement differences among the three. Given a choice I would probably choose this one but I would also be perfectly happy with either of the other two.

Re: errors of "error" models
18 : @Dr. David Kirkby from Kirkby Microwave Ltd :
/g/nanovna-users/message/3181 Hello, Thank you very much for your interest in our work ! We much appreciate that; indeed. Therefore, allow us, please, to inform you that, on the one hand English is -obviously- not our native language, and, on the other hand, we are deeply regret since our limited presentation abilities still create so much confusion to you, even after you already read all of our references on this subject, of course, because these are : "the document" "including adequate references, much like a scientific paper" you ask for. However, and in addition to these, we already wrote, but obviously you didn't notice it too, at: 14 : /g/nanovna-users/message/3111 " this is the current state of published research on this subject, excluding some papers under preparation in order to be published in our small journal: " Nevertheless, it is needless to say that we don't agree at all with your, obviously subjective, comment that "The whole issue is far from simple" - which, by the way, it appears as it is orchestrally emanated from some honorable specialists of this forum - as it unreasonably discourages any Radio Amateur, who is absolute beginner or newcomer to the subject to even give it a chance to attempt to follow it ! And, as your scientific titles imply, it is certain that you know very well that this is the worst anti-scientific attempt to patronize the unsuspecting innocent victim who comes here wanting to learn. Anyway, since we always try to be good listeners, we shall also attempt to follow your valuable subjective suggestions on this very subject and to learn our lessons : Thank you once more ! Now, regarding the objective points you had the kindness to also set, which, we assume, you are definitely referenced to: [17] : From A Common User's Point Of View /g/nanovna-users/message/2521 allow us, please, to also gladly answer them, as follows: (1) You are absolutely right about the "incomplete definitions of the equations". This was a deliberate omission, in order to check how many of the honorable members of this forum - who desperately declare their thirsty for the Knowledge, that is they also passionately seek it in way which exactly coincides with that permanent of ours - are indeed interested for it. Therefore, we also thank you very much, since you are giving us the happiness to notice that: the capital letters are representatives of the "true value" - [ well, if you don't have a feeling of what this exactly [ means, then allow us, please, to inform you that [ you are not alone, but just one of us, and that all [ together we are, with many others who have the [ scientific honesty to admit that they also don't know [ what that really means, because, in our humble [ opinion, this is a notion lying on the boundaries [ between the philosophy and the science, that is it [ is a primitive notion, an undefined term, and all that [ in addition to the fact that there are many others, [ who do not accept that exists such a "true value" - A, B. C of three "known" loads, and Gama is of the "unknown" one, while the small letters are the representatives of the corresponding (VNA or nanoVNA) "raw" measurements, with the rest of the multi-letters to stand for either the well-known indexed S-parameters or for intermediate variables - just for the corresponding indexed Numerators to be used in the calculations and|or the computations - which facilitate, as we hope, not only the comprehension but also the programming, in the way we are mentioning in [17], that is of complex variables as they are all the aforementioned ones. (2) Regarding your interesting contributing notes about the phase matter, allow us, please to reserve ourselves from commenting it right now. Sincerely, yin&pez@arg 18 |

Re: NanoVNA-Saver 0.0.12
Hi Rune,
I tested your new guided calibration routine as well and all works fine with Win10 pro. Very well done! Thank you very much! I keep getting some warnings, and I have no idea if the performance of the NanoVNA will suffer from those!? This is not related to the current version, I had that "feature" with all versions. The messages were generated during calibration. Kind regards Norbert, DG1KPN |
