Bandwidth and sampling rate are not neccessarily tied to each other, so
different scopes will have different correspondences between them, and
if you are measuring a repetitive waveform you can have a slow sampling
rate and still yield good results(assuming a quality instrument). I have
a scope here with the same sampling rate as bandwidth and another with
five times the sampling rate as bandwidth.

Cheerful regards,

Bob
