Signal Name Reference Direction Description
AIGND — —
Analog ground for AI. All three
ground references (AIGND,
AOGND, and DGND) are
connected together on board.
AI<0..63/95> AIGND Input
• For DAQ-/DAQe-/PXI-2204/
2205/2206: Analog Input
Channels 0~63. Each channel
pair, AI<i, i+32> (I=0..31) can
be configured either two single-
ended inputs or one differential
input pair(marked as
AIH<0..31> and AIL<0..31>).
• For DAQ-/DAQe-/PXI-2208:
Analog Input Channels 0~95.
Each channel pair, AI<i, i+48>
(I=0..37) can be configured
either two single-ended inputs
or one differential input
pair(marked as AIH<0..47> and
AIL<0..47>).
AISENSE AIGND Input
Analog Input Sense. This pin is
the reference for any channels
AI<0..63> in NRSE input
configuration.
