Can't save calibration with NanoVNA saver in NanoVNA device,
Hello All,
When calibrate the device (nanoVNA-H) all is 100% OK. When I do calibrate with nanoVNA saver (several versions incl.0.2.2-1), all is also OK 100%, exept lhe last step - saving the calibrtion in nanoVNA-H. No way to save this calibration in nanoVNA-H.I can save it to the Disk only. Seems somewhere I make mistake,,,, Where ? The connection between the Saver and device is established and active. The VNA-H is not prepared to get data ? I have not found the procedure for recording in the device via NanoVNA Saver anywhere. Many things are described how to calibrate, but this is not exactly what it is. Any Help will be appreciated.Thanks in advance, Peter |

just a quick note: On the NanoVNA, you calibrate the device itself, and what it outputs on its screen, and via the USB cable. In NanoVNA-Saver, you calibrate exclusively within the software - it relies on the calibration on the NanoVNA itself remaining constant. This also allows calibrating with more data points than the NanoVNA itself allows. Using the "segments" setting, you can get many more points than the 101 of the device itself. There is no way to save calibration to the device. Neither the firmware, nor NanoVNA-Saver, supports this. Since we are on the subject of calibration: NanoVNA-Saver has a calibration assistant, and 5 manual buttons for calibration. Use the assistant. The manual buttons take whatever is currently stored (and being displayed) by the application, and uses that as the calibration data. It does *not* make a separate sweep for the new standard - it assumes the user knows to do this themselves. The latest version has a warning popup if a user tries to use the manual buttons. I hope you enjoy using the application :-) -- Rune / 5Q5R On Sat, 18 Jan 2020 at 18:58, <s_peter@...> wrote:

Sorry to resurrect a dead thread, but I am still a little confused. Here is what confuses me.
If the device is not calibrated, but I do a calibration on NVNA Saver, is the device then calibrated? So if I connect an antenna will I get the correct results? Or... Does the device need to be calibrated first for the frequency range I want to use? Then will I need to calibrate NVNA Saver? See where I am confused? Again, sorry for the lame question. |
I think DiSlord is incorrect - You can save cal in both environments.

In nanovnaSaver, if there are no cals saved, it uses the devices calibration. I believe there was a forum thread regarding this back at the start of the year. Search out Rune's posts as he is the nanovnaSaver creator. On Monday, June 29, 2020, 12:13:08 p.m. EDT, Brian D via groups.io <sv.takara@...> wrote:
Got it. One of the other but not both. Thanks |
yes, so far i am using nanovna-h without device calibration. Loading

calibration file (From PC) in nanovasver is necessary if device is not calibrated. On Mon, Jun 29, 2020 at 9:50 PM Larry Rothman <nlroth@...> wrote:

I believe Rune said that the NanoVNA should be self-calibrated at least over It¡¯s complete frequency span in order to prevent bad data causing NanoVNA-saver to crash. Then you should cal in NanoVNA-saver. In NanoVNA-saver if you set up multiple segments you really need to calibrate in NanoVNA-saver.

If you want use calibration in NanoVNA Saver, then Need reset calibration on NanoVNA, made calibration on NanoVNA Saver, and use this calibration and always disable calibration on NanoVNA then run nanoVNA saver mode. Or made calibration on NanoVNA and not do it on NanoVNA saver calibration. NOT need made calibration together. it possible, but not need |
