Sampling in TDMS file doesn't match the sampling rate set

[sts123]

Hi,

 

I have this .vi project where I acquire data from the NI-Module and save it to TDMS. The acquisition rate for the TDMS is in the Resample Waveform block.

However when I examine the TDMS in excel it does not match the expected number of samples recorded based on the chosen acquisition rate.

 

I also tested it without the Resample Waveform block, when the rate is directly set in the Task, the TDMS again does not match the expected rate.

 

Any thoughts?

 

Regards
