Saving Measurement from antenna
|
I have a new V2_2 SAA-N which I am trying to figure out. The user manuals explain calabration etc well. The unit works well with the NanoVna- Saver software. My question - I go to the feed point of an antenna up about 30ft outside the shack. I make the measurement. How do I save it so I can download it to the -Saver program inside the shack? The only Save options I find are for saving the calibration. I have already done the calibration for the band for which I plan to measure the antenna for. I must be missing something simple.
Thanks Joe |

You are not, no such feature.
Calibrate at the end of the feed line, measure in your shack. On Tue, 22 Dec 2020 at 18:16, joe gay via groups.io <hamop= [email protected]> wrote: I have a new V2_2 SAA-N which I am trying to figure out. The user manuals |

The NanoVNA is a bit like the 'traditional' V.O.M. - Just gives readings on a meter/display.
There is/are now version(s) with connections on the PC board to add a microSD card for storage, and I believe that one of the newest versions from one of the sellers actually includes the microSD card connector already in the NanoVNA. New owners/users should thoroughly read this group's WIKI and Files sections, but until they get frustrated with their new 'toy' and start searching the web for help, they simply don't know that this great resource even exists. Unfortunately, we often learn of the variations after purchasing an 'early' model. Since the makers and sellers are not large corporations, there isn't a lot of advertising and publicity about the models and features. Not even professionally written instruction manuals - although there is - now - often an included single-sheet chart of the menu system included with a new NanoVNA, but everything else is written by users. (To be fair, it would be difficult for a very small group of the 'tech' people who develop these to also come up with thorough documentation in multiple languages!). And then we have user enthusiasts writing new firmware versions that add even more features! I feel so fortunate to have this resource group. And I feel sorry for all those NanoVNA users who don't know about the Group and for those who cannot read English well enough to use it. At least we do have some wonderful multi-lingual members who do provide helpful information on their own websites it other languages. -- Doug, K8RFT |

Android NanoVNA app supports (AFAIK) "V1" nano only.

That's Hugen the "original" manufacturer and that is only on the H4 version.

The Android NanoVNA app also works with my old 2.8 inch "not-H4" early clone that I bought in October, 2018 (if I remember correctly). That was about 6 months after NanoVNAs became available. It would now be called an 'H2', but back then it was 'the only'. I think I've read that Hugen also created that app.
There are now versions of the NanoVNA with a micro-SD card holder for storing measurement data, too. Search the group postings for more information, and for information about adding Bluetooth communication to the Nano. These features are developed by users, not manufacturers, although I think that Hugen has begun incorporating the memory card slot in some versions now being sold. Not the -F, though - that's from BH5NU, not from Hugen, and uses different hardware and different firmware. (I have a -F too. It's great!) -- Doug, K8RFT |

I remembered something else about using an Android - you must use an "OTG" (OnTheGo) USB cable or adapter for the Android device to recognize the NanoVNA (or other device, like mouse or keyboard, or memory storage device). I was just reminded of that when I decided to try the NanoVNA App on my new Moto G6. It's difficult - the phone has a USB-C connector, and so does the Nano. A straight C cable won't work. All the OTG adapters I can find are for use with a USB-A cable/connector. So at least one more adapter is required!

I simply take screenshots in the NanoSaver app and save them to Word.

I use a program called snag it that is like a screen shot you can resize, crop etc. I paste the images into Word where I add verbiage telling what antenna i¡¯m working on, particulars of the antenna, length, height etc.
I am typically making changes to my antenna setup, so I capture a baseline on all bands, make a change, like length, and capture another series of screen shots on each band of the new results. I last was experimenting with my end fed wire where I captured 10m-160m smith, SWR, r+jX for each band at several different antenna lengths, and with various counterpoise wires attached. I wound up with a 15 page report that I printed out for comparison to optimize my setup for the bands I am interested in. Dallas n5fee |

That is device dependent, most newer devices

can provide power over USB. My nano works without issues on a Nexus 7 tablet that is 8 years old by now. On Thu, 24 Dec 2020 at 20:35, DougVL <K8RFTradio@...> wrote:

The "Official Store" selling the -F, and recommended by the developer BH5NU does not mention storage of readings in the list of features. PC software connected to the NanoVNA can save the SNP data to s1p and s2p files. Maybe that's what he was thinking of. -- Doug, K8RFT |
