Optimizing the Acquisition
The initial acquisition shows the relay contact beginning to open at
the trigger point. This is followed by a l arge spikes that indicate
contact bounce and inductance in the circuit. The inductance can
cause contact arcing and premature relay failure.
Before you take the next acquisition, you c an adjust the vertical and
horizontal controls to give you a preview of how the next acquisition
might appear. As you adjust these controls, the current acquisition is
repositioned, expanded, or compressed. This preview is useful to
optimize the settings before the next single-shot event is captured.
When next acquisition is captured with the new vertical and
horizontal settings, you ca n see more detail about t he relay contact
opening. You can now see that the cont ac t bounces several times as
it opens.
