Optimizing the Acquisition
The initial acquisition shows the relay contact beginning to open at
the trigger point. This is followed by a large 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 can 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 can see more detail about the relay contact
opening. You can now see that the contact bounces several times as
it opens.
