11.5 Trigger Save
Trigger Save refers to saving a set number of data before and after the relevant point: the number of data is set by
parameter. This method is useful when you want to view data from a certain period before and after a certain event.
When Event Save method is used, data are saved after END of each main task where the set bit condition occurred.

Note
After selecting Trigger Save, if the first trigger condition occurs and another trigger condition occurs while
collecting data, the new trigger is ignored and the trigger reoccurrence flag value increases.
Note
If a trigger occurs after collecting one less than the number of sample blocks prior to the trigger, only the
number of blocks collected until then is stored, and the sample is started after the trigger. In this case, the
total number of blocks collected can be less than the total number of trigger blocks
