There was a time when a Vector Network Analyser or VNA was the type of instrument that cost as much as a very fancy car or even a small house. The advent of commodity semiconductors that perform at high RF frequencies coupled with microcontrollers powerful enough to handle the data acquisition and processing might not yet have put those high-perfomance instruments within reach, but at our end of the market it’s opened the possibilities for some useful yet affordable devices. A fresh contender comes from [Jankae], whose LibreVNA tops out at 6 GHz and shows some significant attention to design
Big quote: Apple CEO Tim Cook once famously said “you can converge a toaster and a refrigerator, but those things are probably not going to be pleasing to the user.” Years later, the company is putting the same processor architecture at the heart of both iPad and Mac, but still strongly believes they are separate, complementary devices and that they should remain that way.
If there’s one thing that Microsoft has proven with its Surface 2-in-1s over the years is that there’s definitely a market out there for devices that encompass the best of both worlds — that of the
