PC detects that a trigger condition has occurred which may be thousands of readings later than the actual occurrence of the signal the Daq driver automatically looks back to the location in memory where the actual trigger causing measurement occurred The acquired data that is presented to the user actually begins at that point The latency in this mode is equal to one scan cycle 8 2 Taking Measurements 898095 DaqScan 2000 Series Pre and Post Triggering Modes Six modes of pre and post triggering are supported providing a wide variety of options to accommodate any measurement requirement When using pre trigger the user must use software based triggering to initiate an acquisition e No pre trigger post trigger stop event This the simplest of modes acquires data upon receipt of the trigger and stops acquiring upon receipt of the stop trigger event e Fixed pre trigger with post trigger stop event In this mode the user specifies the number of pre trigger readings to be acquired after which acquisition continues until a stop trigger event occurs e No pre trigger infinite post trigger No pre trigger data is acquired in this mode Instead data is acquired beginning with the trigger event and is terminated when the operator issues a command to halt the acquisition e Fixed pre trigger with infinite post trigger The user specifies the amount of pre trigger data to acquire after which the system continues to acquire data unt
