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?

37 : ann : the uncertainties of our nanovna will be estimated tomorrow

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"..

Something that I have never fully understood is that S21 is supposed to be measured using a "matched load". Isn't the "matched load" of a VNA equal to 50 ohms? Are we to assume that 50 ohms is the

Also, LTspice from Linear Technology (now part of Analog Devices) has been freely avaiable for a long time. There is a Yahoo group, LTspice, which provides excellent support and information. DaveD

Sean,Are you aware that the simulation software call MicroCap is now free? http://www.spectrum-soft.com/ Try simulation first to give you a rough idea of your component values, then prototype and

With respect to matching networks, have you seen W2AEW's Youtube channel? https://www.youtube.com/watch?v=IgeRHDI-ukc Also, do follow the link to W0QE's Youtube channel: SimSmith is very nice
