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

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

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?

For the record, Nanovna-saver looks for Nanovna USB id's For the Nanovna-F I get: usb 3-11: new full-speed USB device number 20 using xhci_hcd [13509.779971] usb 3-11: New USB device found,

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

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

If you'd like to make this diagram slightly narrower, the right-most rows on calibrate and format could be made to go vertically down. On Sun, 6 Oct 2019 at 2:48 PM, Oristo<ormpoa@...> wrote:

Oops, previous menu gif background was light gray; whitened:

There is at least room in the firmware menu to add a "negative delay" menu item, under e.g. "CONFIG"..
