Re: Annotated nanoVNA menu diagram
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,

Re: Annotated nanoVNA menu diagram
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
Re: NanoVNA parallel R measurement
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

Re: info update
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
Re: NanoVNA-Saver 0.0.12
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

Re: Quick compare with HP 8753C...
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

Re: NanoVNA-Saver 0.0.12
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

Re: NanoVNA-Saver 0.0.12
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

Re: NanoVNA-Saver 0.0.12
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

Re: NanoVNA parallel R measurement
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.

Re: Inductor S21 measurement using nanoVNA
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

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

thanks, the smith chart tutorial was nice, the matching network I'm dealing with is a bit more involved as it consists of an emc low pass filter on the rfid chip amp, then the matching L network going

Re: Inductor S21 measurement using nanoVNA
The S Parameters are defined in terms of a circuit within a closed box. Snm is the amplitude of the signal coming out of port n relative to the signal that went into port m. Thus, S21 is the signal
