Connecting Voltage Sources to Simultaneous Analog Input

All sixteen inputs share a common ground that is the same as the digital and analog ground of the GPIC. The differential input signal and absolute voltage of each input should be within the input range of each channel. Refer to the sbRIO-9687 Specifications for details.

The simultaneous sampling analog inputs are differential, so the input measures the voltage between the positive and negative terminals.

If single-ended signals are measured, one end of the signal source and one input terminal should be connected to ground, as in the following diagram.

The gain stage of each input channel can be set as x1, x2, x3, or x4. See Gain Stage for details.
