Description
Use this attribute to specify the amount of time after a Start trigger before a Reference trigger can be recognized. If the pretrigger time (pretrigger samples / 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 pretrigger count.
