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.

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!

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

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.
