software for NanoVNA V2 Plus 4 by joe smith

I first saw him on eevblog and at that time he was reluctant to share his work. His GUI app looks very attractive.

A few days ago I tried to run his software. It installed flawlessly, but when launched it complained about some missed LabView modules (about 10 consecutive dialogs about this). The application finally opened, but I was unable to even switch the COM port to connect to my V2+4, the app didn't respond.

Does anybody made it work in Win10? Do I need to have any previous LabView software in my box? The eevblog thread starts to be huge and is not so easy to find info there. Also, the author seemed a bit reluctant to share his work, so I do not want to pester him with my issues.

Thanks & regards.

My attempt has been on Win7, all OK except a "license request" for ActiveX
virtual driver (or similar).
The COM port is fixed on the default values and also clicking on "refresh"
non other ports appears
(the NanoVNA is on COM27 or COM28 depending on which USB connector I plug
No way to establish the link.

I installed it on a Win10 running within Parallels on OSX10.15.7, I also installed the Cypress driver.
Works perfectly, thanks joe.

Hi all! See my comment on the youtube video about this software.
You need to,install NI VISA. I contacted the author, He probably forget to
include this package.
It work well if you already have NI Labview on your computer, otherwise ,
you hve to install NI VISA, and you will see the com port windows with all
your com port available on your PC.Regards.
I think that the author will include the missing package soon.

Thanks, but I'm still unable to make it work. After installing NI VISA and re-installing Joe's software, when the application is launched nothing happens (no error messages, no window pops, nothing, nada).

A pity, as the software looks superb.

Thanks & regards.

I did not have to reinstal Joe's software.

Joe smith already added the NI VISA package to the new build that he uploaded to github.

F1RVC 2021/01/31 12:43

Yes he added it yesterday, thanks.

Hmm, I looked at that page, I am not very good with software, I see 20 files of the same size and a smaller one plus 2 source code files. Do I have to dl all 20 and then somehow compile them or is one of them all I need to run on WIN-7.


F1RVC 2021/01/31 18:21

Yes put all of them inside a folder and unzip the first one , it will
include all automatically for unpacking...
You will have a new folder with setup inside.

I must be dumb. I downloaded all the files into a folder called nanov2. and unzipped the one called It created new folder called NanoVNA_V2Plus-0.10 in which there are 4 files. I ran the file V2P4_Test_R0.exe and it just came up with an error message immediately about nor being able to find LAbview Runtime_engine. Teh files with numbers on seem to be unused and unchanged! What am I doing wrong? regards Mike

Christian Cziezerski 2021/03/14 21:19

did you get the runtime version 2011 ? That's the version of LabVIEW used to package the executable.

emece67s 2021/03/15 03:04

So, must I understand that, apart from the software (the various zip files), I must install some other software (such "LABview runtime engine")?

I've installed both variants of Joe's software:
* The first one, not including NI-VISA
* The 2nd one, including it
But neither worked. Both showed ~10 error dialogs at start-up complaining about missing procedures/libraries... Then, when trying to connect to the nanoVNA, the first one didn't allow me to select a COM port, whereas the other allowed me, but the Link button did nothing.

Thanks & regards.

"did you get the runtime version 2011 ? That's the version of LabVIEW used to package the executable." I did yes.

emece67s 2021/03/15 14:45

Ok, thanks, so finally the mechanism to install it is:
* Download National Instruments LabVIEW runtime 2011 32 bit and install it (reboot required)
* Download the 21 .zip files from GitHub. Uncompress the first one (this uncompresses all 21) and launch the setup.exe (reboot required)
* Launch NanoVNA_r10\NanoVNA_V2plus ⇒ You did it!!

Thanks, I do have it working now. Regards.

The files are a spanned  ZIP containing the runtime engine as well as NI-VISA.  There should be no need to rename files or to download other files.  I use 7-ZIP.

The software that is included with this spanned ZIP is fairly old.   I ended up moving to a common code base and porting it over to the original hardware.   There are now two branches, one for the V2 Plus, the other for the original hardware.  Once you have the runtime and VISA installed, there is no need to reinstall them.   Just download the software for your hardware and copy it to where ever you like.  I strongly suggest reading the manual before you waste too much time trying to use it.   It's nothing I would suggest a beginner attempt to use, rather stay with one of the many supported programs available.

This short video shows some of the latest changes.
