Probably because for a digital oscilloscope 8 bits of ADC resolution are enough, and 12 an overkill, which cannot be 
said for an SDR application.... with today's standards one should aim for a dynamic range of 120dB, and this implies at 
least 20 *real* bits of amplitude resolution, rarely, if ever, reached by the so-called 24-bit sound cards....
