Oscilloscope Bandwidth Tutorial B

4000 X-Series Oscilloscopes Advanced Training Guide 163

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.
