It looks better without USB connection. Adding a ferrite core improved results with USB connection:

Hi Gabriel - I guess you meant message 6456, and agree that was a poor choice of graphs. I do not calibrate for such a wide range. So, second attempt: Looking at logmag for CH0 and CH1 terminated by

Dear Hans, many thanks for interesting and useful information. My initial suggestion of a scheduled scan has exactly this purpose, to eliminate the influence of cables or operator.

I think the RF on the USB cable wouldn't be an issue. The TX level of NanoVNA is very low. Some ferrites can be added on the USB / UTP cable. The UTP cable can be installed perpendicular to the

Andrew, The support group for the NanoVNA-F that you own is located at /g/nanovna-f . You should leave a message on the board there ( /g/nanovna-f/messages ) and

So, it has been less than a month and my 4.3 inch long little wonder arrived from Alixpress today. It had a Quick Start Guide lol. Are you kidding me? It might as well be encrypted. Has anyone come up

You may also need to add the try group to your user profil. I found that I needed to on RaspberryPi. M Walter

Hi Oristo In the help file search in index for "trace types" there all the various and very many trace types are described also custom traces. The trick is to double click on any trace type name e.g.

apparently "facupov" is pseudo for "from a common user's point of view",

From A Common User's Point of View

Sorry for question, but what means word "facupov"? It is often mentioned here, but I cannot understand what you're talking about... Just tried to google it, but unfortunately with no success

What about RF on the USB cable?

Rune, I attached a screen shot of the image you ask for. That is a full screen of a scan I saved. I noticed when I first loaded the file the image fit the screen perfectly but when I added Marker3 the

If you have calibration data as impedance and delay, but want S11 s1p format, then VNWA software can generate it, according to Kurt Poulsen. I did not expect this "simply" to be so tricky. It appears

I don't entirely agree, Erik. GitHub issues can easily be marked as "enhancement" - I certainly use that a lot to weed out what I need to work on, and what's optional. As long as you're polite,

PLEASE only give feedback on what is supposed to work but does not. Don't submit hundreds of new feature requests as there is only one hugen79 and one edy555 (ttrftech) Github can not be used as some

That detuning should be investigated; I suppose it depends on match between nanoVNA and antenna. For antennas typically using a balun to feed coax, then nanoVNA should have the same. Perhaps running

Rotations are mostly by cable delay, and I guess that differences from 180 degrees between rotations for open and short measurements are provoked by non-ideal open and short calibration

Hi Andy, I cannot support your last statement: That UTP cable is just as much detuning your antenna by common mode current as feeding the antenna by coax without balun would do. Common mode current

Hi Wes, can you send me a screenshot? There shouldn't be any problems fitting in 900 pixels vertical space, unless you're running a lot of markers, or quite a large font... -- Rune / 5Q5R
