Issue Details

I am logging waveform data with an NI-9246. There is a time delay that increases .04 seconds every loop iteration when I log to my TDMS file. Why is this happening?

Solution

You may have a time issue with data logging because your sample rate is being coerced. Refer to page 7 of the NI-9246 datasheet to find which sample rates the NI-9246 supports. Make sure that the dt of the waveform is based off the actual sample rate of your data.
