The default mode is edge triggering which can be set to trigger on a +ve (rising) or -ve (falling) edge using the front panel controls.
Pulse
Selecting Pulse from this menu disables edge triggering and enables pulse triggering. The user must select either Negative or Positive pulse from a sub menu (see below) and is then provided with an Advanced Trigger window (also below).
The example shown is for a negative pulse.
The user can then select options to trigger on a pulse of length greater than or less than the time indicated by the top slide bar. The value of the slide bar is displayed in the box to the right and may be changed by clicking on and dragging the slider.
This triggering method can be an extremely useful tool for finding "glitches".
Delay From Trigger
The Delay From Trigger option also displays the Advanced Trigger and Delayed TimeBase Options window. This allows the data capture to be delayed from the trigger point by a specified time by using the by using the Delay From Main Time Base slide bar.
