3. To set the range of pulse widths in units of time, press Upper Limit (side)
and Lower Limit (side). Enter the values with the general purpose knob or
keypad. The Upper Limit is the maximum valid pulse width the trigger
source will look for. The Lower Limit is the minimum valid pulse width.
The oscilloscope will always force the Lower Limit to be less than or equal
to the Upper Limit.
Set the Level .

Set the Mode and Holdoff.
Mode and holdoff can be set for all standard trigger
types and classes. To set mode and holdoff, refer to Set Mode & Holdoff on
page 3–85. To learn more about trigger mode and holdoff, see Trigger Modes
and Trigger Holdoff on page 3–75.
When you select the pulse class Slew Rate, the oscilloscope will trigger on a
pulse edge that traverses between an upper and lower threshold faster or slower
than a slew rate you specify. To set up for slew rate triggering, do the following
procedures.
Select Slew Rate Triggering.

Positive monitors the slew rate of the positive-going edges of pulses. The edge
must first cross the lower threshold and then cross the upper threshold.
