Grounding Considerations


NI ELVIS does not support floating measurements. Therefore, because the analog channels are differential, you must establish a ground point somewhere in the signal path. As long as the signal you are measuring is referenced to one of the NI ELVIS GROUND pins, the measurement is correctly referenced. If a floating source, such as a battery, is being measured, be sure to connect one end of the signal to the NI ELVIS GROUND. Terminals for the NI ELVIS GROUND signal are located at several locations on the prototyping board. All of these signals are connected together.
