Oscilloscope Bandwidth Tutorial
When we use a 1 GHz bandwidth scope to capture this 100 MHz digital clock, the
result is that we now have a much more accurate picture of this signal, as shown in
Figure 108 . We can measure faster rise and fall times, we observe less overshoot,
and we can even observe subtle reflections that the lower bandwidth scope
masked.
