Whether NI 6259 (M Series) can do AC coupling? I am going to use it to collect acceleration signal and this AC coupling function is important for this purpose. I searched the NI support, and found some materials about the AC coupling. It said that not all DAQ devices support AC coupling. I read through the references of this card, tried to find AC coupling in the DAQmx setting, and didn't succeed. Wondering it cannot do AC Coupling. Is there anybody can give me a comfirmation or any suggestion. thanks!
