G'day!
New to nanoVNA and new to groups.io, so please bear with me..
got my unit three days ago from Aliexpress. It's white, no lizard logo, no RF shielding, no idea what FW it's running and I get only two traces, blue and yellow.
I've done a fair bit of reading and I'm still very confused. One thing I noticed in my readings is that the 2-trace unit is referred to as "antenna analyser" and has better screen resolution?
I'm not ready to start playing with the different FWs.
Antenna testing is all I want to do at the moment but later I would like to be able to play with filters and other RF (VHF & UHF) things.
I'll keep on reading, but in the meantime could some kind soul point me in the right direction re finding out exactly what I've got?
What you have will do the job.
However, new firmware offers new features and bugfixes. It is nothing you must have but it is good to have.
Two track firmware does not have higher resolution. It just uses bigger font so text is more readable. but as memory space is limited, space reserved for two traces data is reassigned for big font. Other than that it is the same functionality. And for usual measuring two tracks are enough.
There is actually one firmware clone that keeps four tracks and offers bigger font. It freed memory by removing Chinese font.
