Description
Analog Input Ground—These pins are the reference point
for single-ended measurements in RSE configuration and
the bias current return point for differential measurements.
All three ground references—AIGND, AOGND, and
DGND—are connected together on your PCI E Series
board.
Analog Input Channels 0 through 15—Each channel pair,
ACH<i, i+8> (i = 0..7), can be configured as either one
differential input or two single-ended inputs.
Analog Input Channels 16 through 63 (PCI-6031E,
PCI-6033E, PCI-6071E only)—Each channel pair, ACH<i,
i+8> (i = 16..23, 32..39, 48..55), can be configured as either
one differential input or two single-ended inputs.
Analog Input Sense—This pin serves as the reference node
for any of channels ACH <0..15> in NRSE configuration.
Analog Input Sense (PCI-6031E, PCI-6033E, and
PCI-6071E only)—This pin serves as the reference node for
any of channels ACH <16..63> in NRSE configuration.
Analog Channel 0 Output—This pin supplies the voltage
output of analog output channel 0. This pin is not available
on the PCI-6032E or PCI-6033E.
Analog Channel 1 Output—This pin supplies the voltage
output of analog output channel 1. This pin is not available
on the PCI-6032E or PCI-6033E.
External Reference—This is the external reference input for
the analog output circuitry. This pin is not available on the
PCI-MIO-16XE-10, PCI-MIO-16XE-50, PCI-6031E,
PCI-6032E, or PCI-6033E.
Analog Output Ground—The analog output voltages are
referenced to this node. All three ground references—
AIGND, AOGND, and DGND—are connected together on
your PCI E Series board.
Digital Ground—This pin supplies the reference for the
digital signals at the I/O connector as well as the +5 VDC
supply. All three ground references—AIGND, AOGND,
and DGND—are connected together on your PCI E Series
board.
