Used With 

All devices 

Description 

daqAdcSetAcq

 allows you to characterize the acquisition mode and the pre- and post-trigger durations.  The

 

mode

 parameter describes 

the style of data collection.  The 

preTrigCount

 and 

postTrigCount

 parameters specify the respective durations, or lengths, of the 

pre-trigger and post-trigger acquisition states.  

Acquisition modes can be defined as follows:  

•

 

DaamNShot

 

- Once triggered, continue acquisition until the specified post-trigger count has been satisfied.  Once the post-trigger 

count has been satisfied, the acquisition will be automatically disarmed.  

•

 

DaamInfinitePost

 - Once triggered, continue the acquisition indefinitely until the acquisition is disabled by the daqAdcDisarm 

function.   

•

 

DaamPrePost

 - Begin collecting the specified number of pre-trigger scans immediately upon issuance of the daqAdcArm function. 

 The trigger will not be enabled until the specified number of pre-trigger scans have been collected.  Once triggered, the acquisition 
will then continue collecting post-trigger data until the post-trigger count has been satisfied.  Once the post-trigger count has been 
satisfied, the acquisition will be automatically disarmed.
