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.
