Description
AIGND
—
—
Analog Input Ground—These pins serve as 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 on the device.
ACH<0..15>
AIGND
Input
Analog Input Channels 0 through 15—You can configure each
channel pair, ACH <
i, i
+ 8> (
i
= 0..7), as either one
differential input or two single-ended inputs.
ACH<16..63>
AIGND
Input
Analog Input Channels 16 through 63 (NI 6053E only)—You
can configure each channel pair, ACH <
i
,
i
+ 8> (i = 16..23,
32..39, 48..55) as either one differential input or two
single-ended inputs.
AISENSE
AIGND
Input
Analog Input Sense—This pin serves as the reference node for
any of channels ACH <0..15> in NRSE configuration.
DAC0OUT
AOGND
Output
Analog Channel 0 Output—This pin supplies the voltage
output of AO channel 0.
