In the help documentation for the ni-scope the maximum delay time is defined in terms of the number of requested posttrigger samples and the actual sample rate. How does this work with continuous acquisition where the number of posttrigger samples isnt specified? The doc also mentions that external clock will affect the maximum delay also, but does not mention how..
I think the number you'd use for post trigger samples is your record length.
Also, what issue are you running into / what are you trying to accomplish that made you ask this question? Typically, wouldn't do a retriggerable task with cont acq
