Optimizing the Acquisition
The initial acquisition shows the relay contact
beginning to open at the trigger po int. This is
followed by 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, th e
current acquisition is repositioned, expanded,
or compressed. This preview is useful to
optimize the settings before the next single-shot
event is captured.
When the next acquisition is captured with
the new vertical and horizontal settings, you
can see more detail ab out the relay contact
opening. You can no w see that the contact
bounces several times as it opens.
