Works well, but needs a User Manual
For NanoVNA V2 Plus4
With no manual, the proper setup, and proper calibration procedure, is guess-and-hope. (Do I terminate both with a 50 ohm load, or just input 0? How do I null-out the length of the cables?) What else can this tool do?
But overall, this is a good tool, and definitely worth the price.
Thanks!

Love this VNA, but
Also, I have heard about a firmware version to support crystal measurements. Is this going to be included with future units?

NanoVna V2 plus 4 delivered today
For NanoVNA V2 Plus4
Without battery I plugged the nanovna to the usb port of my computer and it seems to work well. I can begin to play....
About the shipping: the item was ordered on november the 20th, shipped by SF eParcel and delivered (in my letterbox in France) today on december the 18th. So a delay of less than 3 weeks from China to France, which is very satisfactory.
Thank you to the team for the good job !

After about 1 Year, Damaged ESD ?
Maybe the cause should be ESD or something with the PLL generator above 145MHz.
Do you have some clue based on others related problems??
For repair input switch or ESD protection diode do you have spare components you can sent.
Thank you
Fernando

Quality bit of test gear.
For NanoVNA V2 Plus4
Easy to use, good protective case and a sensible battery choice that is easy to source and replace as required.
The slightly improved specs over the 2_2 are a nice addition as well.
I use it on the bench connected to the computer and also at the feeding of Antenna's.
There is no comparison to the early NanoVNA's -which did have their place of putting a hobby grade instrument into the hands of many, but easily outgrown.
The value for money is very good and you can spend a lot more and not get much more in terms of performance.
A useful instrument to keep around.
