I use a Bird SiteHawk Sk4000 antenna analyzer at work and had to repair it once.
When I opened it up, I discovered that Bird engineers used a slightly modified Samsung 6" cellphone for the display and processor brains of the unit.
All of the RF guts were inside a solid shielded module.
The RF module was connected to the Samsung through its USB (OTG) port.
So - something similar could be designed to take advantage of all the Android (and possibly iOS) cellphones and tablets with multi-core processors and HD displays.
As mentioned earlier in the forum, maybe a headless version of the nanoVNA could be designed that goes up to 2.4GHz or higher that has a USB interface only.
For anyone interested, the SK4000 apk can be downloaded from the BirdRF website to play with.
Regards,
Larry
