That will tell you how much noise to expect. Ways you could improve that noise is to add termination resistors near your ADC, add ferries, shielding around your cabling, using a differential ADC & twisting your wires etc. This mostly assumes you are worried about induced noise and not system noise. Also, this might be a good read ni.com/white-paper/3344/en/#toc4 | |
