HW topic CLAD Guide LV2017: DAQmx specific time target and behavior prediction
Solved!
Hi All,
The attached VI is quite used in the CLAD Preparation Guide. What happens if the time target is multiple of the acquisition time?
This specific situation does not appear in the CLAD Guide but it's a possible situation. Even using LabVIEW and run the VI I can´t clarify the question. Not clear the size of the array in the data indicator.
3 rows x 2000 columns OR 4 rows x 2000 columns
Thank You!

Yep, it can be either of those. Since we are dealing with software timing, there is A LOT of jitter. So it can go either way on that third iteration.
This discussion reflects the type of practice and discovery that we highly recommend as excellent preparation for the CLAD. When you understand the timing deeply enough to see these gaps, you've got that topic mastered. (My intent in this response is to avoid unnecessary stress for you and others.) In the actual exam, we avoided this type of edge case by careful selection of the parameters and the range of specific answers. If you discover otherwise, during the exam go with the most likely and please report it to us afterwards.
Also please keep in mind, these VIs were created to highlight timing and sampling rates -- they are not necessarily recommended for real-world applications. We frequently discuss the relative value of presenting only best-practice VIs vs using simplified VIs that allow deeper focus on a particular aspect of LabVIEW.
Best Regards,
Hello,
Today I've passed the CLAD Exam. Thanks for your help with the preparation of the exam.
