A decent spectrum analyzer would need good image frequency (and spurs) suppression. And it would need a much faster ADC because a 5 or 10 KHz bandwidth is way too low to be useful. I need a real time spectrum analyzer that can capture at least 10 MHz of spectrum at once. In essence, a spectrum analyzer is more complicated than a vna. However, they have quite some hardware in common. It is on my wish list to design a decent 6 GHz VNA/SA combi, not a cost optimized VNA "toy" like all nanoVNA versions. But the wish list grows faster than I can handle...

Although, thinking about this a little more - there IS alot more space for enhanced firmware on the new V2 board which uses Analog Devices freq generator chips so additional functionality -might- be able to be developed for a spectrum analyser feature using the input port.The problem is the dynamic range and how to control input levels.
What do you think, Gabriel?
It would also be nice to have an option to flip the display 180 degrees.

Not really worth it when there are countless RTL-SDR dongle projects that allow you to do this already on the cheap.

is there any plans to make a spectrum analyser along the same lines as the nanovna?,seems to me it would be a winner.
