PCI-MIO-16XE-10, PCI-6031E, PCI-6032E, and
PCI-6033E and should be set to 1. Dither cannot be
disabled on the PCI-MIO-16XE-50, PCI-MIO-16XE-10,
PCI-6031E, PCI-6032E, and PCI-6033E.
Unip/Bip Channel Unipolar/Bipolar—This bit configures the ADC
for unipolar or bipolar mode. When Unip/Bip is set, the
ADC is configured for unipolar operation and values read
from the ADC Data Register are in straight binary format.
When Unip/Bip is clear, the ADC is configured for bipolar
operation and values. The data values are two's
complement and automatically sign extended.
Gain<2..0> Channel Gain Select 2 through 0—These three bits control
the gain settings of the input PGIA for the selected analog
channel. The gains shown in Table 3-3 can be selected on
the PCI E Series boards.
