There is no official manual as the app started out as a hobby project for the author's personal use. A such there is no support. However you can search the message archive of this group and find a fair amount of information.

Good suggestions. Also worthwhile are "The Missing Manual" and "NanoVNA V2/ S-A-A-2 User Manual". I've read those and have used the V2Plus 4 some success as I already know a fair amount about RF and associated instrumentation. Here, however, my question is specifically on information regarding the nanoVNA-APP software for Windows. I know something of NanoVNA-QT and nanoVNA Saver but nothing on the nanoVNA-APP for Windows. That's what I'd like to find out more about.

There is no "installation". Extract the contents of the .rar file to a folder of your choice. Create a shortcut for the executable in a place where you can find it and you are done.

Please remember that you need to un-rar the file.?

Thanks for the file link. That's the installation executable for windows? Is there a page or site that describes it or information that you can point me to?

Searching turns up too much and too little info at the same time. If you're new this nanoVNA phenomenon and not an all out nanoVNA enthusiast and aficionado, it's very difficult to follow and understand all the references and threads, especially as many are loose with nomenclature. A little help from an actual aficionado can go a long way in helping a neophyte get started.

Lou,
Download and read the "Absolute Beginner's Guide" in the forum's file section as well as Barry's slides:
/g/nanovna-users/message/22977?p=,,,20,0,0,0::Created,,posterid%3A1005447,20,2,0,83826635
Browse the forum Wiki sections as well - there is a lot of info to take in!
Best of all - play with your new device - build a jig and plug in coils and caps to see how they affect the Smith Chart, etc.

Thanks OneofEleven,
Error hasn't re-occurred ... I started using the -App because of the simple methodology to update Firmware ... and found it easy and straight forward to use ...

Don't forget the TinySA, you probably need one of those to. I paid somewhere around $50-$60 for mine. It's another great tool to have around.

The NANOVNAs are NOT spectrum analyzers. They are Vector Network Analizers.

You may want to look at the Tiny SA which IS a spectrum analyzer:



However, I have both and would recommend both for the capabilities of each.

I've been wanting to buy a Spectrum Analyzer for a while, however, due to
the high price, I couldn't buy it. I recently discovered the Nano VNA
Analyzer that would be a low-cost outlet.

Robin, truly excellent teaching!

Thanks for taking the time to illuminate.

Peter,

it helps to think of the active devices, the PA power transistors, as
horribly non-linear devices. The base-emitter junction is a forward
biased diode, whose small-signal parameters vary over an RF cycle. The
collector-base junction is a reverse biased diode (think varicap diode

<>), whose capacitance (Ccb)
depends on the instantaneous value of the collector-base voltage. That
capacitance is then subject to the Miller effect
(
<>), and can provide
positive feedback from output to input.

Generally, the stage voltage gain is kept quite low to avoid any
danger of the apparatus becoming a power oscillator rather than a
power amplifier.

And since the base emitter junction is a diode, it obeys (more or
less) the diode equation for AC resistance, r'= .025/Ib?Ω, where Ib is
the base current. There is a lot more going on, for instance see

<>.

All that capacitance has an impact on the tuning of the input and
output networks. At this point, you might be thinking that any
functioning RF amplifier is a triumph of engineering ingenuity over
the Laws of Physics. You would not be far wrong.

PS: It was a good question, but with a complex answer, depending on
how much detail one can cope with!

Ian,

I have the 2plus4 VNA and found the nanoVNA-App for Windows the "best" software tool for my needs. The VNA-QT is vy simple, the VNA-Saver does sweep -slooooow- and I do not like the trace resolution. Mr. Smith LabView soft is vy nice but more for testing C, R, L, Xtal etc..to confusing for me...and have other nice tools for those measurements.

Using the VNA here for RF-filters, Duplexers, Diplexers, Isolators, Antennas, Tuner and LPF-Alignment, Attenuators etc etc.....

The 206Version of the nanoVNA-App does not show the -errorbox- on startup here, and I had to find out a Firmware, which works with the 2plus4 and the App. This is a version from
Dislord V2Plus4 v1.0.64 noFPU.bin ( thank you Dislord) and this combo does vy well here. Maybe you will give it a try ?

To OneOfEleven, sri that this real fine software is no more in your line of support .... but I know the stressing demand of some users is frustrating.... all the best for you !

Kind Regards
Helmut

The mA referred to is the programmable current drive strength from the output device of the si5351, which is related to the output power at the source port.

When I received my hardware I downloaded and had running "nanoVNA-saver" as expected.
That was several versions of my OS - Ubuntu - ago.
Now I am on 21.04 , following same "git - hub" download instructions and so far no "saver" .
Since "nanoVNA-saver " is written in python I added several python packages to my current OS , but still no go.

If you don't want to cope with python's dependency system, the you can
also try the all in one binary blobs.



Download and unzip the file. On MacOS and Linux you will have
to make the extracted file executable via 'chmod +x file'.
Then you can execute that binary.

Just another little bug in the NanoVNA-App software Ian.

If I were to write it again I'd do things a little differently, such as make it much easier to follow and edit the source code.
It started as just a simple little piece of test software for my own use, but kept getting requests to develop it further, so I did (without much thought of how it's laid out etc).

Thanks for your response. I got a bit confused because units are in mA and
usually power units are dbm or dbd, or in watt. Thanks a lot for the
clarification. I will leave it in auto for the present time.
Best regards

this option not for battery calibration.

NanoVNA use si5351 generator, it allow generate 4 power level signals.
For some measures better use max power setting, for some less.
Select power option need before calibration!

Good evening everyone,
I bought a NanoVNA-H from a fairly well-known Asian site. It was delivered to me on time, with the two cables with SMA connectors and the "open" "closed" and "load" calibration plugs.
I have performed a firmware update to version 1.0.45 as of January 30, 2021.
I observed that in the new menu there is a Power calibration option. Could someone explain to me how to properly calibrate the internal battery of the NanoVNA-H from its menu?
Thank you in advance for your comments and advice.

Mine has a STM32F072CBT6, which - according to the data sheet - offers 128K.

And even if you have a ..C8 device, it usually typically has 128K.
In automotive electronics we call this "umbrella device", the supplier just builds a generic chip and names it differently depending on what you ordered - in most cases the devices are not even screened and selected.
No need to worry, even the original FW is always >64K.
