In sampling theory the BW is determined by the half of the sampling rate. But in a scope things seems to be different if I'm not mistaken.
But for example if you look at the front panel of the oscilloscope model TDS1002B, among other things two things are written. It is written 1GS/s and it is also written 60MHz.
So the BW is explicitly given here as 60MHz. On the other hand if we apply Nyquist law we could have also conclude the BW is half the sampling freq. so 1GHz/2 = 500MHz. So where am I thinking wrong here?
