Fig. 3-2 Single-ended input channel connection
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-1710/1710L/1710HG/1710HGL/1716/1716L,
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
same voltage. The difference between the ground voltages forms a
common-mode voltage (V cm ).
