One ususally buys an 'scope that can handle a comfortable amount over the nyquist rate. http://www.pfarrell.com/prc/bits.html RedBook audio is 1,411,200 bits/second So if you are looking at RedBook, 5 or 10 mHz is a nice bottom. This is nothing for a modern 'scope, so getting one that does 50mHz is 'safer' If you want to see jitter, or other things much smaller, then mHz is not enough, and you'll need gigaHz. this starts to get expensive and weird. At GHz, the wire in the signal sampling leads changes the signal. _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
