6 Set the sequential softkey to on.
7 Press the # of points softkey, Then, use the keypad or entry knob
to set the # of points to 100.
Set the number of points to capture the event of interest. For this exercise,
100 points are used because each pulse takes up about 100 points on the
screen, and because this exercise is using a pulse as an event. You could also
have used 200 points to capture two pulses, or 25 points to capture part of a
pulse. You can also increase the sample rate to use more points to capture
the pulse.
Press the # of segments softkey. Then, use the keypad or entry
knob to set the # of segments to 10.
Set the number of segments to capture the number of events you are
interested in. Below the selected number of segments is the maximum
number of segments allowed. You may notice that as you increase the
selected number of points, the maximum number of segments the scope can
capture decreases. For this exercise, 10 segments were chosen, so that 10
pulses are captured.
