Application Examples
Optimizing the Acquisition
The initial acquisition shows the relay contact beginning to open at the trigger
point. Thi
s is followed by a large spike that indicates contact bounce and
inductance in the c ircuit. 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 (push the Single button again), you can see that the
contact bounces several times as it opens.
