3.3 Analog Input Connections

The PCI-1710/1710L/1710HG/1710HGL/1716/1716L supports both

16-channel Single-Ended or 8 differential A/D Input, however the

PCI-1711/1711L only supports 16 single-ended 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-1710/1710L/1710HG/

1710HGL/1711/1711L/1716/1716L provides a reference ground for

external floating signal sources. Fig. 3-2 shows a single-ended

channel connection between a floating signal source and an input

channel on the PCI-1710/1710L/ 1710HG/1710HGL/1711/1711L/

1716/ 1716L.
