♦ Slope - Edge Type
Specifies in which direction across the trigger Level the Source
must change to trigger data collection.
Figure 26: Trigger Selection (2)
As the type of slope, select:
Rising Edge – Data collection is triggered when the value of
the Source rises from below the trigger Level to above the
trigger Level, i.e., when the change is from LO to HI in I/O.
Falling Edge – Data collection is triggered when the value of
the Source falls from above the trigger Level to below the
trigger Level, i.e., when the change is from HI to LO in I/O.
Data Change – Data collection is triggered when the value of
the Source crosses the trigger Level in either direction.
No Trigger – Data collection will start at the same time as
START TRACE is clicked. All other trigger settings are
irrelevant.
♦ Level - Trigger Level
Specifies the threshold value of the Source at which data
collection is triggered. The units for the setting are the same as
those of the trigger object selected in Source. The trigger level
cannot be set if the trigger object is I/O 1 or I/O 2.
♦ Pre-Trigger (0% to 99%)
A buffer of data is collected even prior to the trigger condition
being met. This allows FlexWorks to include the period before
the trigger in the graph. The Pre-Trigger setting specifies how
long this period should be, as a percentage of the duration of
the graph after the trigger.
