Oscilloscope Bandwidth Tutorial B

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.
