Dear All,
I want to use NanoVNASaver for continuously reading and storing S1.p data i.e. automating my experiments for long duration tests (few hours). Since there is no LabVIEW tool available for NanoVNA, I tried to use the Saver version v0.3.8 but with no success.
Would be great if someone has already a tip or solution in this context.

Best Regards
Adnan

Adnan,
Do a search on the message forum for OCTAVE (similar to MATLAB)

There is a lot of info on using it with the instrumentation library - that may be useful to you.

There is some python code in the NanoVNA repo that gives examples of how to access the NanoVNA, send commands, and retrieve data. It's somewhat simpler than NanoVNA_Saver, which is also Python.




For your application, you don't need the fancy graphics in NanoVNA-Saver.

The NanoVNA app by One Of Eleven has this feature built in. It records .s2p files that contain the S11 data that you need. You go into continuous scan mode and then click the record button. It writes about 30 or 40 files per minute.

To use it you need to update your firmware. You can find the app and the necessary firmware here. I use the latest DiSlord version 1.0.45 instead and it works great. It is .rar compressed format ( like zip ) so you need a program like 7 Zip (free) to decompress it.

Bundle of thanks for your reply.

The NanVNA app seems to work for continuous recording (s2p along with s1p) up to 1 GHz, however I am using NanoVNA v2 and the measurement frequency of interest is between 2-2.5 GHz. Is there any other similar app available for the aforementioned frequency range?

I have a general question. What is the deal with the # symbols in the
subject line, in this case, "#features #nanovna-saver"? Is it some kind of
a secret code?

There is a Labview package for the NanoVNA V2+ and V2+4 written by joeqsmith. It is discussed on the eevblog at the link below which is the most recent discussion. He originally did not release this software because he did not want to offer user support. He has kindly released it and a manual BUT do not ask him for support. You can read his posts and the user manual and figure it out yourself.

eevblog link -
manual link -
software download - multiple zip files -

I have not used this software so I can't provide any more info. You will have to modify it to record the files but if you are a Labview user that should not be much trouble.

Good luck - Roger

It's called a hashtag. A trendy, modern thing. I have not found a use for it.

It's called a hashtag.

Properly used it's supposed to make message searches easier.
Only if it's used correctly, only for those that do search before they post a question.

I can do searches just fine without it. I don't see the necessity for it.

Properly used it only links to other subjects with the same hashtag - it's superfluous in a group like this and should be constrained to twitter where the trendy junk originated from..
