Hi I have an oscilloscope with a 50 mhz bandwidth, its time/div goes down to 2ns so far so good.However I have seen 100mhz scope with a time/div of 2ns and 50mhz scopes with a time/div of 5ns. Ok now i'm confused, I know bw is the 3db roll off but how does this relate to the time base? seems to be arbitrary and manufacturer dependent.Any one any info?
