Can someone please help me understand what Nanovna I bought and how, if possible I can use it.
I see SAA-2N on my front panel of the vna. I have tried to find a match in the sea of information. NADA..
I have tried to get it to boot to my PC..NADA. I pulled up the so-called version no, it is 20200617
Nothing matches..It says Board NanoVNA V2_2. It's brand new and it has sat in the box til now.
Is it JUNK? Can I get some form of updates? If so where? are there exe software instead of raw compilers?
I haven't a clue how to compile anything.
Please help.Thanks--

Hello Bill!
You have a clone.
You can download this firmware for your 2_2 version with 4 inch display:

https://nanorfe.com/downloads/20201013/nanovna-v2-20201013-v2_74.bin

or experimental, but good:

https://nanorfe.com/downloads/20201124-experimental/nanovna-v2-20201124-experimental-v2_74.bin

By https://nanorfe.com can you find a manual for this last official version.

Please download NOT FW for V2Plus or V2Plus4 - it is other hardware!!!

Best regards
Vladimir, dl7pga

Hello Bill!

Please see item # 1371 for the latest firmware for all V2 versions from user DiSlord. Please pay attention to the information about FPU in the device.

Vladimir, dl7pga

A vector network analyzer is a powerful measurement instrument for RF, it is not a software development toy. Learn how to use it for measuring parameters of your filters, antennas, amplifiers, RF components and so on. Start to use it as is, later when you are familiar with this tool and have a set of proper HW bits and pieces for it you can consider updates and other GUI and whatever.

I am not sure what you mean by " I have tried to get it to boot to my
PC.". You must load a program to run the device and one often used is
VNA_QT which provides ability to use most if not all of the VNA services.
However, I have experienced the inability to run the program with the VNAs
on a ThinkPad by Lenovo using Win 10 while an old HP laptop running Win 7
ran on the first try, This happened with two different models of the
VNAs. One solution which works according to reports is downloading new
firmware and here I suggest asking others or reading earlier messages on
such topics. The older computer gives it a new task and needs no
significant risks or playing around.

Hello Bill!
As first - on Website https://nanorfe.com ist most information to NanoVNA V2 (SAA-2) and user manual.

As second - please download and install the driver and program NanoVNA-QT for windows.
Without this driver cannot operate with SAA-2N on PC!!!

https://nanorfe.com/nanovna-v2-software.html

With NanoVNA-QT you can upgrade firmware of your SAA-2N.

I have written you over the firmware.

Best regards
Vladimir, dl7pga

Hi Bill,
Let's start with a more basic procedure, instead of connecting to the PC and trying to update the firmware. Those things can be accomplished, next month of, later this year.
So, dig out the VNA and 3 CAL elements. Set the NanoVNA to a stimulus of Frequency (start) =100MHz and Frequency (stop) =200MHz, then set the display to Smith Chary and perform a CAL using the open, 0ohm short and 50 ohm load. Then save the CAL. Then go find any 2 meter antenna and connect it to the nanoVNA. Change the display to SWR, to read the SWR of the antenna.
Now, you are on your way!!

Hello Vladimir,
Looks like you exactly know what we are talking about here, therefore I plea
for your help because I'm confused too...

I purchased the 4" display SAA-2N on Amazon From AURSINC: [NanoVNA SAA-2N V2.2
](https://www.amazon.com/gp/product/B08G4GXTKK/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1)
Config/Version says
Version: git-20201117-9659de4
Port Info: GD32F303
Board: SAA-2N
Has FPU: yes.

So, what did I get and what's the right pattern to upgrades?

Dear Max,



Although I only have a small version with the 2.8 inch display and SMA
connectors, the SAA-2N version basically has an SAA-2 board with N connectors
and 4 inch display. In terms of software it is the same. The first FW for V2
with 4 inch display is dated 20200619 (Github). But there is no such thing at
nanorfe.com



<https://nanorfe.com/downloads/>



The earliest FW version there is 20200926, followed by 20201013, 20201122
(bugs) and 20201124-experimental (good!). The 20201117 compilation was used in
production, but should be the same as the 20201013 compilation. The
designation of the FW for V2 (SAA-2N) with the 4 inch display is, for example
for the 20201124-experimental,

nanovna-v2-20201124-experimental-v2_74.bin in folder
<https://nanorfe.com/downloads/20201124-experimental/>



All other files are either for 2.8, 3.2 inch or, like V2Plus, V2Plus-ST7796,
V2Plus4, intended for other hardware, NOT for version 2.2 (2_2) with 4 inch
display.



The Nanorfe downloads folder also contains newer versions, but ONLY for the
V2Plus (2.8 and 4 inches) and V2Plus4 (only 4 inches!).



That's why I put a note on the forum post # 1371, where user DiSlord shows the
latest versions of the FW and explains what the FPU is all about. In the
archive loaded in the article there are FWs for the devices with and without
FPU. The FW without FPU support works with all, whereas the FW with the
support of FPU only works with the devices with. There are such devices too.

Please read this post from DiSlord. As a developer, he can explain everything
better.



Best regards

Vladimir, dl7pga

P.S. In Attachment is the FW for the V2 device with 4 inch display with FPU
support - 4 inch display has 480x320 pixel (SAA-2N)

Vladimir,

i just experienced the same scenario while looking for a path of upgrades for my Amazon purchased nanovna saa-2n. Hope to see engrained support for the product on this site.

Hello Vladimir,
Thank you for your help.
I now understand there are several hardware platforms with different display
(and connector) solutions.
I updated the firmware to the revision you suggested, everything went well and
smooth.

Unfortunately, looks like there is not any officially released V2Plus4 (latest
hardware, if I'm not wrong) with 4" display and N connectors.

No, apart from SAA-2N there is no device with the N connectors. The latest
V2Plus4 with 4 inch display also have SMA connectors. SAA-2N remains an

Они разобраться с разъёмом не могут? Или с версиями приборов?

I think that the located transition from sma to n connector does not benefit the device.

I am a bit confused too, but I blame this on the glass of whiskey.

May I say, this has been a tortuous thread, some of it not in the accepted communal language for the forum, and an embarrassing degree of quoting previous messages.

Summarise:-  V2.2 can only use v2.2 firmware. There are two versions with different drivers for the two screen resolutions (2.8” and 3.2” or the 4”). Dislord has rewritten the V2 firmware and the faster version makes use of the floating point unit (fpu) to speed up calculations - therefore four versions.

I find the v2N ideal (I have two of them) as it is heavy enough not to slide around the bench, it fits in the hand and has beefy connectors. I have had no trouble from them.

Ultimately, when you buy a complex device, you should expect to devote a period of time to learn about it and how to use it, if you have not used one before. That is not the responsibility of the manufacturer. Someone who has never driven a car before cannot expect the car manufacturer to supply a comprehensive handbook of driving complete with driving licence for the purchaser. Most new drivers spend some time and money learning to drive first and maybe a just a few minutes looking at the brief manufacturers info on how to use the satnav etc.

In the past, the leading manufacturers of vnas did offer education courses to new users at a huge additional cost to the purchaser (or his employer). Most employers hoped their technical staff (selected at the job interview) already knew how to use the kit.

Steve L.   (PS  I am a retired medical doctor and I am still learning about vnas, on these forums and the wider internet. I taught myself about spectrum analysers 30 years ago by making one).

This unit has a super Dokumentation and is perfect for education, just google the call sign and check. Yes I have one, I also have two nanovna’s and a professional Astech VNWA. I am happy with all of them. I would even be happier if the nanos would have the option to select a log freq. scale, see above picture.

For me, if I am using log it's because the weighting of the data set.  The problem isn't plotting the data in log, it's running a log sweep.  To work around it, I run a quasi log sweep basically running small segments of linear sweeps in but calculating each segment as a log.   I find that some software doesn't like the Touchstone data this produces.

Vladimir... THANK YOU for this comment: "No, apart from SAA-2N there is no device with the N connectors. The latest V2Plus4 with 4 inch display also have SMA connectors. SAA-2N remains an exception."
I was very much wondering about this. I am awaiting mine here next Friday.
Thank you again..... much appreciated. Mine will be a clone too.... with N type connectors and a 4" screen. and  aluminium case.
In my opinion... SMA connectors are too fragile for this type of a device,
Thanks again....
Albert EI7II.

are you sure about case be in aluminium?!?

as far as i know the saa2n has a steel case and the v2plus4 has an
aluminium case (i do not know details about the other half a dozen clones)

the n connectors ... are sma to n adaptors screwed (and secured with
some solder) on the "normal" sma connectors

so in fact the saa2n ... is a "normal" v2 ... with 4 inch screen and
those sma to n adaptors

and those n sockets (adaptors)... are held from the sma sockets and not
secured well to the case

There is a reason why they were additionally soldered!

Hi Sigi... Grusz Gott.
No, I am not sure at all.... the case looks steel to me, but somewhere I
read that is was aluminium !

As far as am concerned... it's steel, feels like steel... smells like
steel, sounds like steel AND it weighs a TON.
I am totally new to the use of the NanoVNA... so am a raw novice. The
first one I got had a screen defect. But it worked... but the screen
defect meant that you could nor properly see the calibration symbols on the
L/H side.
One thing I need to mention..... the Vendor support was absolutely AMAZING,
even though I guess they are in China... replies with 24/36 hours, and
exceedingly helpful... they immediately acknowledged that I had a faulty
unit. and a free replacement is on the way to me. I bought it from Amazon
USA... as neither Amazon DE or UK had the unit available. The support guy
has a Chinese call sign and writes perfect English...... just a pleasure to
deal with them.

This is the Unit I am awaiting: NanoVNA SAA-2N V2.2 Vector Network Analyzer
Metal Enclosure 4.0" inch with 3000mAh 50KHz -3.5GHz Measuring S
Parameters, SWR, Phase, Delay, Duplexer, Smith Chart HF VHF UHF Antenna
Spectrum Analyzer

Sigi... I note your point on the N connectors... but i prefer them far
above PL259 or SMA. I no longer work on 23cm stuff so the N's will be fine
for me.
Thanks very much for getting back to.
Alles Beste...

Will a magnet stick to it? Granted, if it’s stainless steel, a magnet won’s stick, but I doubt they’d use stainless for the case. If the magnet doesn’t stick, it’s probably aluminum.

As far as am concerned... it's steel, feels like steel... smells like steel, sounds like steel AND it weighs a TON.

i have both .. an saa2n and a v2plus4 ... saa2n is steel and v2plus4 is
aluminium

I just did the magnet test on my SAA-2N, and it sticks. At least in the case of my SAA-2N purchased ~Nov-2020, it has a steel case.

FWIW:  Some stainless steel is magnetic, and some is magnetic when work hardened but non magnetic after annealing.

Thanks for the comment, Lou. Yes, I knew that, and perhaps my original comment was a bit too broad, and possibly misleading, regarding stainless steel and magnetic properties. Some stainless steels are indeed magnetic, but I doubt if the manufacturers of the SAA-2N would have opted for a stainless steel case, due to the added expense.

I apologize for misleading anyone into thinking that *ALL* stainless steel alloys are ‘non’-magnetic, but as a very general rule, a magnet will not stick to most inexpensive, garden-variety stainless steel alloys. But my original premise stands -- the fact that the magnet sticks does rule out that the case was aluminum, which was the ‘question’ I was attempting to answer.

Thanks again for the comment and correction, Lou.

Same.... magnet sticks. Problem solved. Makes sense... aluminium, tends to
be more expensive than steel.
Irrelevant for me.... even if the case was made from sourdough.... as long
as it adequately protects the unit.

Hi:

I am problems with getting my V2 to work via laptop. The problem seems to be with the driver. Which windows do you use, and which driver?

Hello Ray!
Here is the driver for all V2 Versions

https://nanorfe.com/downloads/NanoVNA-QT/CypressDriverInstaller_1.exe
I use Windows 10 Pro 64 bit without any problems.

1. please driver download
2. driver install
3. Connect Your NanoVNA V2 via USB to PC
4. Turn on . When switching on the PC emits a beep.

You can update the FW with NanoVNA-QT or NanoVNA-APP. My favorite program is NanoVNA-APP 1.0.206 or 1.0.207 from OneOfEleven.

Best regards
Vladimir, dl7pga

Hi Vladimir and group,

I followed your directions 1-4 exactly. Indeed my pc donged.

However:

1. In the device manager, PORTS do not appear, neither with the VNA on nor off.

2. What does appear when the VNA is turned on is “USB to UART Adapter”, Universal Serial Bus controllers. Clicking on properties reveals that the manufacturer is Cypress.

3. I tried to operate VNA View software. Under the Device menu, I see grayed out :

a. Select Device

i. No devices found; check dmseg or device manager

4. I tried to fun VNA saver 0.3.9. Under serial port control, nothing appears in the serial port box. There is not response to “rescan”. Under “manage” I am informed

a. Status: Not connected

b. Firmware: not connected

In short, much to my sorrow and disappointment, I’m still stuck.

BTW, I have tried to install various USB drivers besides Cypress, using in Device Manager the Action/add legacy hardware command. I manually chose Ports. These have included the HP communications Port, the Microsoft USB serial model device, the @i: Quatech Q-linx parallel adapter, and the STMicroelectronics virtual Com Port. All of these install, but display the little yellow warning triangle, and in short, don’t work.
On the other hand, the Denso Wave Active USB does install successfully (no yellow triangle and Properties says the device is working properly). But toggling the nanoVNA on and off does not change its status, the only change is that the USB to UART adapter appears and disappears, and the two nanoVNA software packages still fail to recognize the nanoVNA device.

If you or anyone in the group have further suggestions, I would be grateful.
Also, if you could send the URL from which “NanoVNA-APP 1.0.206 or 1.0.207 from OneOfEleven” can be downloaded, I would be appreciative. Maybe I will be able to use it, once I overcome this driver problem

Hello Ray!
Download link for NanoVNA-APP 1.0.206
https://disk.yandex.ru/d/vwlBFKHEpU8Gyg ( https://disk.yandex.ru/d/vwlBFKHEpU8Gyg )
unpack with programs winrar or 7zip.
Easy start this program from folder.

I do not - I have no problems with Sypress driver and NanoVNA V2.

73 de Vladimir, dl7pga

Sorry, program version is v.1.1.206

Dear Vladimir:

Thanks!
I think my problem is on the driver-windows level, not the driver – nanoVNA device level. None the less, I’m stuck, at least for the time being.

Thanks for the link – I will download it in anticipation of somehow solving the driver problem.

do you know if the drivers really installed? a lot of drivers won't install unless you disable "driver signature enforcement" another winblows "feature"

Dear Dennis and group,

Thank you for your comment. I can only answer on the level of “Drivers for Dummies”: When I installed these various drivers via the device manager, they appeared on the device manager list under Ports. However all of them, except Denso Wave, appeared with the little yellow warning triangle, and Denso Wave did not seem able to connect to the nanoVNA. I would value your interpretation.

Your message seems to imply a possible solution, i.e. to disable “driver signature enforcement”. I would be grateful if you could explain what this means, and even more so how to do it, at the level of “Drivers for Dummies”, or point me towards a URL that does so.

Thanks and regards,
Ray

a lot of usb-serial drivers have to be installed twice it is a two step process, I ran into this with a model railroad device.
in fact the best explanation i found is the instructions for the SPROG DCC device drivers i mentioned at this link.
note toward the end of the process where it discusses the second install. http://www.bbmgroup.com/sprog/install/SPROGIIonW8-10.pdf

of course use your rivers not the SPROG drivers shown in the instructions

Dear Dennis:

I will try this….TNX

Dear Dennis and group:

I tried to follow the recipe in http://www.bbmgroup.com/sprog/install/SPROGIIonW8-10.pdf with adaptation to the Cypress driver. Specifically, I disabled the driver signature requirement, installed (got the yellow triangle, and under device status, the following “This devices is not working properly because Windows cannot load the drivers required for this device (Code 31)” I then did multiple updates, but got messages that “The best drivers for your device are already installed”, and the yellow triangle remains.

So, in short, I have not resolved the problem. Anyone have any other suggestions?

all i can suggest is
1

sorry something happened.
1 if there was a reboot during the install sequence driver enforcement would reset and need to  be disabled again (thanks Microsqueeze)
2  when updating drivers don't let winblows search for driver but point updater to your Cypress file (if it gives you the option)

failing that i'm out of ideas

Dear Dennis,

1. It did not reboot

2. I pointed to the Cypress driver

Dear Group:
Has anyone else (besides Clyde) experienced this problem? (inability to install functioning Cypress USB driver for nanoVNA.v2)
Better yet, has anyone overcome this problem?

Hi, Erich Kaltenbrunner!

A good friend recommended NanoVNA to adjust doubler filters. In my case I intend to build a duplexer with 6 cavities on the 2m band (144-148 Mhz). So, I ask: with a NanoNVA is it really possible to make adjustments in duplexer?

I can't understand why you have replied on my post about me trying to locate the Missing Manual in groups file section ,your query is about Duplexers,now I'm confused 🤔

for 2m?? an older nanovna ... or the nanovna v2

both should do it (more or less)

getting a good "notch" of 90 to 100 db in the rx chain on the tx
frequency is the tricky part ... or your repeater will become deaf

good luck

ps ... use good cables and a good load to calibrate and also when
loading the duplexer on the not used port

https://nanorfe.com/downloads has removed 20201124-experimental.  I have the Aursinc NanoVNA SAA-2N V2.2 and I installed firmware 20201013 and it is for 2.8 screen and messed up my device.
Can any one save me by providing the firmware I need to restore my device?  It would be MORE than appreciated!  My unit is useless unless someone helps me recover.  My device still installs firmware files, so i could recover.
Thank you, Doug

In the manual , boot procedure.....
Push left button while power on , and upgrade with the good one...

And then you could upgrade with your old firmware version you saved before
upgrading with the bad one.
