I have a doubt about the recorded data by NI cDAQ 9234 (data obtained by accelerometer transducers). I am recording data with Rate (Hz) 2048 and samples to read 1024 and acquisition mode : continuous samples.
Now, to undestand the time between two samples, that it is equal to 1/2048= 0.00048828125, but in the file obtained by "write to measurement" the sampling rate is 0.000488 or 0.000489 and it changes in a random way ( I think that it is normal because the software have to do an approximation because it is not possible to have an integer real sampling rate).
My doubt is if there is a way to correct this random way to changing values, and more important, if the software works with the correct value (therefore 0.00048828125) but the problem is only the data in the time stamp.
Finally, if there is a guideline where I can study in depth these problems.
I am attaching a jpeg about the problem.
Thanks a lot for the availability and the help.
