3 Advanced Triggering, Search & Navigation, and Segmented Acquisition Labs

Your scope’s display should now look similar to Figure 31. Using the

scope’s default rising edge type trigger, we can see two distinctly different

rising edge speeds on this waveform. Also notice that the slower

transitioning edge appears dimmer. This is because the slower

transitioning edges occur less often than the faster transitioning edges.

Perhaps these slower transitioning edges are in violation of meeting

minimum required specifications. Let’s first set up the scope to measure

the rise times of this signal, and then we will set up the scope to uniquely

trigger on the violation edges.

9 Press [Meas]; then tap the Ty pe softkey.

10 Select the Rise Time measurement; Once on, tap Statistics and then

Display On.

Figure 31 Scope display reveals two different rising edge speeds when triggering on any

rising edge.
