I am kind of new with national instruments. I am trying to acquire voltage from a sensor with NI 9220 and force with NI 9237. Both of then presents high level of noise. I have already connected the NI9174 chassi in a ground cable and i am using mode differential for acquisition.
Funny is when i conect the sensor in another acquiriment system (spider 8.1 - HBM - an old model), the noise goes away. I have read that national instruments provides a good signal and good quality for measurements. It doesn`t make sense, i can guess i am doing something wrong. Does anyone can help me please ?
