Differential Connections for Ground-Referenced
Signal Sources

Figure 4-4 shows how to connect a ground-referenced signal source to

a channel on the PCI-MIO E Series board configured in DIFF input
mode.

Figure 4-4. Differential Input Connections for Ground-Referenced Signals

With this type of connection, the PGIA rejects both the common-mode

noise in the signal and the ground potential difference between the
signal source and the PCI-MIO E Series board ground, shown as V

Figure 4-4.
