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 use 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 (when
you push the SINGLE SEQ button again), you can see more detail
about the relay contact opening. You ca n now see that the contact
bounces several times as it opens.
