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.
I went to use my nanovna v2 plus and it won't boot. It has a white screen and flashes off then back on with the white screen. I put a battery in to see and it boots properly however it doesn't seem to make correct measurements anymore. If I plug it in while the battery is in then it turns off and on again but boots. Not sure if this is a software or hardware issue. Any help would be nice.
