Analog Input Signal Overview

The AI signals for the NI 6013/6014 are ACH<0..15>, AISENSE, and

AIGND.Connection of these AI signals to the device depends on the type

ofi nput signal source and the configuration of the AI channels you are

using. This section provides an overview of the different types of signal

sourcesand A I configuration modes.More specific signal connection

informationisprovidedintheConnectingAnalog Input Signals section.
