Optimizing the Acquisition
The initial acquisition shows the relay contact beginning to open at
the trigger point. This is followed by a large spike that indicates
contact bounce and inductance in the circuit. The inductance can
cause contact arcing and premature relay failure.
You can adjust the vertical, horizontal, and trigger controls to
optimize the settings before the next single-shot event is captured.
When the next acquisition is captured with the new settings, you can
see more detail about the relay contact opening. You can now see
that the contact bounces several times as it opens.
