I bought a China function generator and while it does not have a software upgrade there are several components to be changed that make it function better at higher frequencies. I heard some cars have functions that can be turned on and off remotely so they can charge you yearly. The sat and cable TV is like that . The equipment is the same but they only enable the channels you pay for.
