How Width Trigger Works
Width trigger allows you to define a positive- or negative-going pulse width bounded by a voltage
level, above or below which a trigger will occur. You can specify a pulse width and voltage range,
within or outside of which a trigger will occur.
Width Trigger Setup
1. In the menu bar, touch Trigger, then Trigger Setup... in the drop-down menu.
2. Touch the Width trigger button
3. Touch inside the Trigger On data entry field and select a source on which to trigger:
4. Touch inside the Level data entry field and enter a value using the pop-up numeric keypad.
5. Select positive or negative slope.
6. Touch the LessThan button and enter a pulse-width value in the Upper Limit data entry
field. Or touch the GreaterThan button and enter a pulse-width value in the Lower Limit data
entry field. Or touch the InRange button. Touch the Delta button
to set up a nominal
range, plus or minus a delta value in seconds. Touch inside the Nominal Width and Delta
data entry fields and enter values using the pop-up numeric keypads. Alternately, touch the
Limits button
to set up a precise pulse-width range. Touch inside the Lower Limit
and Upper Limit data entry fields and enter values using the pop-up keypads. Or touch the
OutOfRange button and perform the same range setups as for InRange triggering.
