The only discrepancy - which is fatal to the software working - that I have seen thus far, is that the developers have changed the prompt line, which I use to detect when output from the device has

Kurt, Good points for more precise calibration. It would certainly be more precise than my suggestion. I certainly agree with you that it is a good idea to calibrate as close to the measurement plane

Hi Bryan You are forgetting that the female female adaptor has a delay which when removed shift the measurement plane away form the calibration plane. I have a suggestion which work with good

Hi, In reference to Alex_M modified version, nanoVNAv1.03TDRb4 doesn't use Python anymore to measure TDR cable length. neb

Should read: "However, I don't think it will run everything directly." -- Bryan, WA5VAH

Hi Stan - Sadly, that little horizontal twig just right of "Press control" block is hard-wired for all vertical branches and would be pretty hard to remove for only one; I tried... I may try again,

associated help file content is revised, but not yet for firmware updates (the next step): https://oristopo.github.io/nVhelp/html/nVhelp.htm

Maybe also put "Press control or touch screen for menu" into a horizontal box, and on 1 line instead of 3, similar to the "Display" box, and have the left side of it even with, and above, the

Hi Sean, Your VNA will be used to measure your antenna or other elements in shunt form or it could be used to measure in series through form, that would be a S21 measurement. However, for sake of

I had the .dfu file generated and uploaded. The edy555 firmware didn't convince me ... then I discovered that I have a problem with all types of firmware (NanoVNA-edy555, NanoVNA-H): If you execute

Hi Herb, I would actually suggest holding back for just a few days; NanoVNA-Saver 0.1.0 doesn't work that well with 0.2.2. The problems should be fixed in my next release. :-) -- Rune / 5Q5R

I have been a long-time user of Matlab; however, the license (number 12652) I use professionally cannot be used by me in a private setting. I recently learned of GNU Octave at

Rune, Thanks for the heads up. I've been hesitant to upgrade to the 0.2.2 firmware because I haven't had a compelling reason to do so. I think you just gave me one :) Herb

Paul, Feedback from users so far is that the command set for the NanoVNA-F is not fully compatible with the NanoVNA and, therefore neither NanoVNA-saver or NanoVNASharp work with it. If the only

IMO, you are probably better off measuring the series impedance and converting it to a parallel impedance because of the inaccuracy of the NanoVNA when measuring very high impedances.

Hi, aa_talaat, Here is a suggestion. I would recommend that you connect the inductor from the center conductor of port 0 to the ground of port 0 with the shortest possible wires. If you could, I would

I have 2 old but new metal pens with a nylon tip. Previously used to transfer rubbing letters and stripes to a copper print for etching. Works great !

Has anyone looked at S21 for a mixer as DUT, where other mixer input is e.g. sinusoid or sawtooth?
