Optimizing theAcquisition
The initial acquisition showsthe relay contact beginning to open at
the trigger point. This is followed by a large spike that indicates
contact bounce and inductance in the ci rcuit. The inductance can
cause contact arcing and prematurerelay failure.
Youcan use the vertical, horizontal, and trigger controls to optimize
the settings before the next single-shot event is captured.
When the next acquisition is capturedwith the new settings (when
you push the SINGLE SEQ button again), you can see more deta il
about the relay contact ope ning. You can now see that the contact
bounces several times as it opens.
