Pretrigger of Event Data
The pretrigger can be specified in trigger mode.
This function is used to save the data before the point where the trigger condition
is met as event data. This function is convenient when you wish to record the data
before the occurrence of a certain event such as when an alarm occurs.
Specify the pretrigger as a percentage (0, 5, 25, 50, 75, 95, or 100%) of the recording
time (data length) of the event data. If set to 0%, the data after the trigger condition is
met is recorded.
