Beware of cheap underperforming clones

As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.

See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.

Marker Scale & Values on Display

Michael 2021/02/02 11:16

I'm trying to learn to use the NanoVNA (SAA2N) that I have and working on measuring some CMCs (thanks to Dave E for his helpful info) but there is one thing that keeps stumping me.

I have 3 Traces Active; 0, 1 and 2, along with 2 markers that I'm using on the display of the VNA.
Scale & Values for all 3 traces show up at the top in the appropriate color for each trace.
When I touch on one of the markers to move it, the Marker to a different frequency, the Values show up for the markers. OK fine...
However, I can't figure out how to get BACK to the original Scale & Value for all 3 traces.

So far, the only way I can get back is to save the Config, reboot and Restore the configuration. Then the 3 Scales & Value will show up again.
There's got to be an easier way, but I just can't find it.

Mike,

see the attached file.
Maybe it could help you.

Martin,

Thanks for the reply. I had seen that document before (and saved it to my iPad in my Acrobat App for future references).
I did go through it again, in pretty good detail. In all honesty, I learned a couple more things about the VNA, clarifications on channels, and things like that.

However, I didn't find an answer to my question.
When you start up (I'm starting from a saved configuration) The Active traces show up in color, along with the Scale & values for each.
If you touch one of the markers with the stylus, the Active traces at the top are replaced with the Marker information, Frequency & Value. Touch another colored marker and it's Freq/Value shows up.
I can't find a way to get back to the original Active Traces with the Scale & Values for each.

I figured that since you changed it by touching a marker, there should be another touch to return it, but I've been playing with it for over a half hour and the only way I can find to return, is to restart the NanoVNA & restore my configuration.
I also went through the "Marker" menus, and all the other menus, but couldn't find a way to get back to the Scale/Values.

I'm running the SAA2N Owocomm, Version git-20201117-9659de4 (Build date Nov 17, 2020)
