3.3 Analog Input Connections

The PCI-1712/1712L supports either 16 single-ended or 8 differential analog inputs. Each individual input channel is software-selected.

Single-ended Channel Connections

The single-ended input configuration has only one signal wire for each channel, and the measured voltage (Vm) is the voltage of the wire as referenced against the common ground.

A signal source without a local ground is also called a “floating source”. It is fairly simple to connect a single-ended channel to a floating signal source. In this mode, the PCI-1712/1712L provides a reference ground for external floating signal sources.

Figure 3-2 shows a single-ended channel connection between a floating signal source and an input channel on the PCI-1712/1712L.

Differential Channel Connections

The differential input channels operate with two signal wires for each channel, and the voltage difference between both signal wires is measured. On the PCI-1712/1712L, when all channels are configured to differential input, up to 8 analog channels are available.

If one side of the signal source is connected to a local ground, the signal source is ground-referenced. Therefore, the ground of the signal source and the ground of the card will not be exactly of the
