That is a good idea. I just started using NanoVNA-saver because it's in Python, and I'm familiar with scikit-rf.

This is a tricky measurement even with a high grade VNA. A compact article on the topic is at:

NanoVNA firmware can send uncalibrated data, then calibration need use in external software But by default NanoVNA send calibrated data (if calibration apply on NanoVNA) in this case not need made

I need to measure a very low impedance device for a non-ham application.....probably less than 1 Ohm.? Is the NanoVNA able to make an accurate measurement on such a load in the 14 MHz range? 73,

Rune had a good suggestion where you calibrate slot 0 in the NanoVNA for the maximum frequency range you would ever need and then leave it that way and use the other slots for other frequency ranges

I'm not sure about the accuracy implications - there are some numerical precision effects that would need to be looked at. I believe there is a "scanraw" command in some of the firmware versions that

Well, saver and the device are two completely separate entities, with some versioning differences to boot (e.g. NanoVNA-Saver works with lots of different devices). But yes, some summarizing and

I fully support this view of Chris! I also thought that the calibration of the NanoVNA Saver was independent of the NanoVNA. Otherwise 'Save' of calibration in NanoVNA Saver makes no real sense (as

Nanak Nagar = NanoVNA Autocorrect needs fixing also!! ;-) -- Regards, Chris K2STP

Interesting discussion…. Me thinks the calibration procedure/protocols/software for BOTH the unit, and software (saver) need to be fixed/made more user friendly. Especially for non-tech users like

I've had mixed luck with https://www.thingiverse.com/thing:3818979 depending on the fit of the cover. I can't find the one that was similar to that but included a cover. I ended up trimming off the

Mine came from thingiverse. I love it.

It is perfectly clear now. I firstly had made the calibration on the NanoVna and saved that in slot 0. Then connected the NanoVna (by pressing the "Connecting to device"). Selected the wanted segments

I'm not so sure about that.? The interface (over the USB) doesn't expose any way to know whether the nanovna is sending calibrated or uncalibrated data to NanoVNA-saver. The data command with
