Is there a instruction that is not in Chinese? I asked the vendor for some info and got a Chinese PDF
Frank

I found this set of instructions.
Any use?
My unit not yet arrived.

I think the best way to create instructions, is build your own. That is what I am doing as I use the instrument and try to get inside the developers head! Once you do this it is pretty easy to do various things over and over and get consistent results. Otherwise you find yourself experimenting endlessly till you get a reasonable working function!!

You can access additional commands by connecting the unit to your PC, opening a terminal on the VNA's serial port and type the help command at the prompt.
You will get a list of all the commands available through the VNA's console.
I used this to calibrate the touch surface using touchcal.
Unfortunately, it doesn't store the touch calibration update.

Thanks Larry, good info. Alan

Hello all. I have the same instructions, plan to do someday in Portuguese. At time the most confused part is the calibration, didn’T figure yet if it take long to stabilize, if its like put open, short and load and press calibrate...

On the calibrate, the firmware routine does not appear quite right.

In any case, what I found that works consistent is the following:


1. Select stimulus and start and stop frequency
2. Select CAL and then CALIBRATE
3. Connect the 50 ohm to CH0
4. Press LOAD and then PRESS ISOLN (Note these are highlighted in black at first and then ISOLN goes green)
5. Then connect a THRU cable form CH0 to CH1 and press THRU
6. The firmware takes you to DONE. IGNORE!!!!
7. Now connect an OPEN to CH0
8. Press OPEN
9. Connect a SHORT to CH0
10. Press SHORT
11. Then finally press DONE
12. And SAVE

That's it. Check and be sure that the open, short and 50 ohm are on the proper side of the chart.

P.S. Let me know if not clear or if I missed something. NOTE, this is for the 2 trace or 2 track VNA. Not the 4 track or S11/S21 measurement device. Although I suspect the cal routine is no different.

Workedine. Thanks. Now I can make some tests on some handheld antenas. And in a 4m antenna that was about to build.

Great and good luck. Have Fun. Best 73' Alan

You can store the touch calibration us saveconfig command.

Good to know, thanks.
What other settings will the saveconfig command save?

That's all there is to it. Connect the open , press open. Connect short, press short etc.

All the units are based on the same hardware. This from "A Guide to the NanoVNA":
The current design of the NanoVNA and the name was created several years ago by a Japanese ham under the pseudonym “edy555”. His first design ideas with a different DDS (frequency generator) seem to date back to 2013, but the current design with a significantly reduced parts count and based on the Si5351A was published by him in 2016. Edy555 himself references a German kit, the VNWA3 which was based on the concept of using a cheap computer soundcard, published by Tom Baier, DG8SAQ in the Mar/Apr 2007 issue of QEX ("A Low Budget Vector Network Analyzer for AF to UHF"). In the summer of 2016, edy555 announced to produce the NanoVNA, which was apparently done afterwards, but the kits were predominantly sold in Japan. Edy555 was also involved in the original firmware and continues to support the firmware (see chapter Two). He decided to open-source hardware and firmware to avoid bad clones, which undoubtedly was key to future development and the current popularity of the NanoVNA. It was not until a Chinese ham, Gen Hu (pseudonym ''hugen'') adapted the design slightly by changing the power supply and started to mass market the NanoVNA, that the device created international interest. In agreement with Edy555, hugen sells his product under the name NanoVNA-H. Hugen also runs his version of the firmware.
