Operation
Delay
Delay between recording and trigger event.
Pre-trigger Select a negative delay time to detect signals prior to the trigger event.
• In the oscillograph, the trigger time is designated by a dotted line.
• With triggering on occurrence of an event, it is thus possible to detect the values that
have caused the event.
Post-trigger Select a positive delay time to detect signals occurring a certain time after the trigger event.
Edge
If the trigger source is a channel or a variable, you can choose between the following trigger
modes:
Positive edge For triggering on a BOOL variable:
• Trigger activation requires a FALSE-TRUE transition.
For triggering on a different variable:
• For trigger activation, the selected trigger value must be exceeded.
Negative edge For triggering on a BOOL variable:
• Trigger activation requires a TRUE-FALSE transition.
For triggering on a different variable:
• For trigger activation, the selected trigger value must be fallen below.
Change For triggering on a BOOL variable:
• Trigger activation requires a status change.
For triggering on a different variable:
• For trigger activation, the current value must be different than the last value.
