Hi For me the analog bandwidth is a bit too low, this means that 250kHz sine can be digitalized with 80 samples per period. I think that 20MS/s is a some kind of a whistle, it cost a little, maybe a bit finer sampling accuracy plus some software to handle this. Another curious thing in product brochure is:
