Device-Specific
AI Ground—These pins are the reference point for
single-ended AI measurements in RSE mode and the bias
current return point for DIFF measurements. All three
ground references—AI GND, AO GND, and D GND—are
connected on the device.
AI Channels 0 through 15—You can configure each
channel pair, AI <i, i+8> (i = 0..7), as either one differential
input or two single-ended inputs.
AI Channels 16 through 63
(NI PCI-6031E/6033E/6071E only)—Each channel pair,
AI <i, i +8> (i = 16..23, 32..39, 48..55), can be configured
as either one differential input or two single-ended inputs.
AI Sense—This pin is the reference node for AI <0..15> in
NRSE mode.
AI Sense 2—This pin is the reference node for
AI <16..63> in NRSE mode.
Analog Channel 0 Output—This pin supplies the voltage
output of AO channel 0.
Analog Channel 1 Output—This pin supplies the voltage
output of AO channel 1.
AO Ground—The AO voltages are referenced to these
pins. All three ground references—AI GND, AO GND,
and D GND—are connected on the device.
