System event The following system events serve as trigger source:
•Fault,
• Warning
•Error
Direct trigger No trigger condition, recording takes place immediately after clicking the symbol in
the oscilloscope toolbar.
Value Value from which on triggering is activated.
Deceleration Delay between recording and trigger event.
Unit: [%]
Trigger delay Select a negative delay time to detect signals prior to the trigger event.
• In the oscillogram, the trigger time is marked by a dashed line.
• When triggering on occurrence of an event, it is thus possible to detect the values
that have caused the event.
Select a positive delay time to detect signals occurring a certain time after the trigger
event.
Edge Three trigger types are available:
Positive edge First, the selected trigger value must be fallen below and then exceeded in order that the
trigger is activated.
Negative edge First, the selected trigger value must be exceeded and then fallen below in order that the
trigger is activated.
Change For triggering on a Boolean signal source:
• Trigger activation requires a state change.
For triggering on a different signal source:
• The current value must be different than the last value in order that the trigger is
activated.
