The bandwidth is the -3dB input bandwidth for the scope, so it's telling you the maximum frequency it can see.

Keysight DSOX4022A Oscilloscope old rule of thumb is get a bandwidth that's twice your frequency, although sometimes 3 or more times can be helpful depending on what you're working on and what you need to see. Here's a reference article all about oscilloscope features. The article you link states the 'rule of thumb' to be that the sampling rate should be 3 to 4 times the bandwith, but I feel like all the Tektronix scopes I've worked with have a sampling rate of 10 times their bandwith.

Keysight DSOXA, 2 Channel, MHz Bandwidth Oscilloscope

Keysight DSOX4022A Oscilloscope So it depends on the equipment you have, how fast your going, and how much you can pay: You should also be aware that if your input signal is not a pure sine wave it also contains harmonics with much higher frequencies. For accurate acquisition you have to cover at least some of these harmonics. At the frequency of the maximum bandwidth here MHz a sine wave of this frequency is attenuated by 3dB by the analog frontend of the scope.

The sample rate specifies how many measurements are done by the scope per second i. Not the answer you're looking for?
