Triggering on External Waveforms

Use external triggering when you want to display waveforms on inputs A and B while triggering on a third signal. You can choose external triggering with automatic triggering or with edge triggering.

1Supply a signal to the red and black 4-mm banana jack inputs. See Figure 29.

In this example you continue from the Trigger on Edges example. To choose the external signal as trigger source, continue as follows:
