    Bandwidth is the most important parameter in selecting oscilloscope.

     

    For bandwidth, you can confirm it by check how high frequency of your signal is?

     

    For example, when you test a USB, the highest reading frequency is 240MHz and writing frequency is 184MHZ, but you can't only select 300MHz bandwidth, because  if you also need to test harmonic in the signal, you always will select  more than 3 times as base frequency.
