The regular tinySA has a 434MHz first IF and the low input is as listed in the wiki. Just like the old HP spectrum analyzers when you remove the input low pass filter you can do all kind of tricks like harmonic mixing. I have the SW to show it is working? (till above 3GHz) but the "signal identification" (just like on the old HP SA) is difficult to explain and I am not sure people will like it. So I do not expect this will ever be a product.
We are investigating other options but for now I suggest you go for a RF Explorer WiFi combo or something similar, but the display of the RF explorer is much smaller? than the tinySA.
