No, sorry for the confusion. Ideally I would have no jitter in the data.
As I currently have the program wired, my acquisition and logging loops employ a data queue. The message 'Start' is sent to the acquisition queue, which calls itself over and over, (and sends the data via queue to the logging loop), until I press stop.
I would like to program it so that I can change the front panel settings (delay and duration) so stop the logging...I am not sure how I would implement the 'duration' as exactly as I can
