10 or more what? Cycles of some wave? If you are manually making
moves and recording velocity, you should only get one event.
You would want the sampling rate of the unit set VERY slow, like
100 samples/second, when doing servo tuning. That way, you get
somewhere around .25 to 1 second filling the screen.
