nanoVNA for Dummies


 

It's always bewildering to wander into someplace and find that you're trapped inside
someone's jargon jungle. I've found myself in that shape when I wandered into the
nanoVNA Users group.

I'm a noobie when it comes to the nanoVNA. I've owned a miniVNA but the gui is far different.
The interface presents measurements according to known task names making selections a lot
simpler. The price difference between the two is 10 to 1. When the magic smoke got let out of
miniVNA, I knew I needed a much more affordable instrument. I don't need lab grade for what
I do hence my purchase of the nanoVNA, a good deal.

I came to this group looking for help. I'm sure it's here but filtering through the myriad of messages
make the discovery task a chore. The user manual really isn't too much help. It is obviously written
by someone whose first language is not English but the effort is appreciated. Looking for help in
the various messages means wading through much expert-speak to get to a simple explanation.

What is needed by this oldie-newbie is a manual, or series of tutorials, which give, step by step,
instructions which uses the nanoVNA to perform simple(?) tasks. For instance, proper calibration
is emphasized throughout many messages but nowhere are there instructions which show how to
perform calibration. And if more than one calibration type is required, a tutorial which shows how
to do each.

Something else, there is a document which details the console commands for the nanoVNA. What
application is used to communicate with the device? Surely not the touch screen! And if you
communicate serially through the USB port, what are the parameters of that port?

For other tasks to be performed by the nano, just look at the miniVNA document referenced elsewhere
in this forum. It's a good document but, as I said, the user interface is far different from the nano.

Folks, I'm not complaining (well, maybe I am ... I'm old and in a hurry), but I just want to get along
with my learning so that I, too, can acquire a new expert-speak language, voila'!

Hi Bruce,

Try this file:

/g/nanovna-users/files/NanoVNA%20Calibration%20Considerations%20and%20Procedure_v1.0.pdf

It is in the FILE DIRECTORY FOLDER.

Also, there is a MENU breakdown flow chart that is very easy to follow and will provide quite a bit of assistance with the manual in hand.

Here is the MENU flow chart:

/g/nanovna-users/files/Miscellaneous/nanoVNA%20Menu%20Structure%20v1.1.pdf

This is helpful as it permits you to get an eagle eye view of the instrument soft key flow top view.

Thanks Alan,

Somehow I missed these ... or failed to read them in my haste. RTFM. I'll read
carefully to see if it serves what I need. Been spoiled by being spoon fed by
the miniVNA interface, I guess.

Still, I have learned new terms which will be helpful.

Thanks again,

Bruce, K4TQL

This easy to understand HP document, from which I learned a lot, could be entitled "S-Parameter Techniques" for Dummies.
