Issue Details

I had a Field Point with the module FP-AIO-600 now I'm using a cRIO with a NI 9203 and the signal aquired is affected from a lot of noise. 
What could be the problem?

Solution

The new module that you are using (NI 9203) has an input bandwidth of 850 kHz while the FP-AIO-600 has an input bandwith of 350 Hz. Probably you did not see the noise with the field point because the frequency of the noise is higher than 350 Hz.
To solve this problem you can implement an hardware low pass filter or a software low pass filter to reduce the input bandwith of the NI 9203.
