Gary,
If it is anything like the NanoVNA that I use regularly, it will be that I basically turn it on using the built in screen.
Every thing else is done with the USB cable and computer. It makes the screen virtually as big as your screen.
I use a 15" laptop and it is awesome.?
I used it at our amateur radio club and a 1/2 a dozen people gathered around my laptop as we tuned a filter viewing it on the 15" screen.
