3.3 Analog Input Connections

The PCI-1710/1710HG card supports either 16 single-ended or 8

differential analog inputs. Input channel configuration is selected by

software. Selection by software is more convenient than selection by

a slide switch on the card. In the past, if you set one single-ended (or

differential) input channel by switch, the other channels also would be

single-ended (or differential). But on the PCI-1710/1710HG card, if you

set one single-ended (or differential) input channel by software, the

other channels will maintain their original configurations.

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

referred to 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-1710/1710HG card

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-1710/1710HG

card.
