I have set my scope to 40Ms/s and a time span of 50uS resulting in a expected 2kpts waveform on the screen. 

When I then get the waveform with labview I got 32kpts. I don't understand why. 
Thanks for any help/tips you can share with me.

I would imagine that it gets set in the Read Waveform vi that was not attached.  32K just so happens to be the max value of an I16 (+32767).

The vi was attached to the scope. 
I got the answer from someone in the labview community. The scope interpolate the extra point by default. When I switched interpolation off I got the expected 2k points.
