The NI 9219 Module is sold as a " 4 AI, 100S/s/ch simultaneous Universal Measurements".
The point is that I cannot have 100 Hz data acquisition.
I only have around 2 Hz.
In NI-MAX, I saw that I only have 1.95 Hz.
Is there something wrong in my configuration?
Have you tried changing the frequency to 100? The frequency field is user configurable.
