Beware of cheap underperforming clones

As of 2023 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Plot print function


cocopuppy 2023/04/14 16:26

Is there any SW that will allow you to print a plot? I use it for documentation on eBay, and it wold be nice to have the file name or description of the plot in the file. Right now, I just use snippet\
The program I use to connect is vna_qt.exe  v1.1
Thanks

Nanovna_app can take Screenshots of your v2. Any paint or similar soft
(IrfanView as an example) can work with them. Or.. You can use the app plus a
screen grabber (hardcopy, print screen etc) and use that.

I'm trying to figure out what you have, and what you need.
You have a data file and you want to plot it? or you have a plot image, and you want to add some info to the image?
For the latter, there's a ton of semi-automatic ways to do this - for example ImageMagick or ffmpeg can both superimpose text on an image, so you could have a small batch file or script that takes the filename of a image file, and creates a new image file with the filename embedded in the image at a specified size and location.

Thanks for the reply. I use snippet to make a copy of the actual plots, and need a way to label the before I print it. Right now all I have is the file name I save it as.

I have posted some items I am selling on eBay, and trying to figure a way to put a description that people can see what the plot was for

cocopuppy 2023/04/18 09:44

I have tries that, but it becomes a real job when you have 5 or 6 plots. Is there was a way to save the files with the “name” somewhere on the picture

Thanks

Frank

Siegfried Jackstien 2023/04/18 19:05

you can change the name when saving via the nano app

if you use a screen grabber (hardcopy.exe or similar) then also there
you can give the file a name when saving .. so where is your problem?

either the screen of the nano itself ... or the screen from the windows
app ... both can be saved and both can get its filename when saving ...
HMMM?????

Exactly - those are flavors of ImageMagick

Thanks

cocopuppy 2023/04/22 15:08

OK, how do I do it? Is there a text function in the NanoVNA V2?

Frank

cocopuppy 2023/04/22 15:11

The file name is different, but when I load them on eBay, it ONLY has pictures, no file names

ImageMagick is available for Windows, and you can use a batch file (or
PowerShell) to do the titling. I don't recall it off the top of my
head, but there's a way to iterate through all files matching a pattern
in a directory, and you'd just use file name as both the "file to be
edited" and the "text to be superimposed".

something like

for %%f in (*.png) do (
superimpose %%~f /text %%~f
)

I have to go look stuff like that up every time I write a batch file or
shell script.

Actually, imagemagick is pretty sophisticated, it might have the
iteration through a wild card file thing built in. Well, I know it does
for stuff like converting all png to jpg for instance, but I don't know
if it can auto populate the text with the filename
