6.9.4 Pre-event and Post-event Triggering

The range for this offset is 4096 to 2E9 points. As shown in the following figure, when the offset is

negative, the values at the beginning of the data record represent samples taken prior to the

trigger. When the value is 0, all of the values are taken after the trigger. Values greater than zero

can be used to program a delay time from the receipt of the trigger until the data points that are

entered into the buffer are valid.
