Description

Use this attribute to specify the amount of time until the next record's Reference trigger can be recognized. If the posttrigger time of the current record plus the pretrigger time of the next record (posttrigger record n + pretrigger record n+1 / frequency) is greater than this attribute, then the holdoff value is ignored.

This attribute is especially useful when you want each device in a multidevice situation to recognize the Reference trigger at the same time, though the Reference trigger is shared among devices and each device has a different record size.
