Page 4: Analog Input
Analog Input The NI PXIe-7861 provides connections for 16 AI channels. Each channel has an AI+ pin, AI- pin, and AIGND pin to which you can connect both single-ended or differential voltage signals. Use the AISENSE pin to connect non-referenced single-ended signals. Connecting Single-Ended Voltage Signals To connect referenced single-ended voltage signals to the NI PXIe-7861, you must connect the voltage ground signal to AI GND in order to keep the common-mode voltage in the specified... -
