Signal Reference Description

AI GND

—

Analog Input Ground—These terminals are the reference point for single-ended AI measurements in RSE mode and the bias current return point for DIFF measurements. All ground references—AI GND, AO GND, and D GND—are connected on the device. Though AI GND, AO GND, and D GND are connected on the device, they are connected by small traces to reduce crosstalk between subsystems. Each ground has a slight difference in potential.

AI <0..207>

Varies

Analog Input Channels—For single-ended measurements, each signal is an analog input voltage channel. In RSE mode, AI GND is the reference for these signals. In NRSE mode, the reference for each AI signal is an AI SENSE.

For differential measurements, AI 0 and AI 8 are the positive and negative inputs of differential analog input channel 0. Similarly, the following signal pairs also form differential input channels: AI <1,9>, AI <2,10>, and so on.

AI SENSE, AI SENSE 2, AI SENSE 3, AI SENSE 4

 —

Analog Input Sense—In NRSE mode, the reference for each AI <0..15> signal is AI SENSE; the reference for each AI <16..79> signal is AI SENSE 2; the reference for each AI <80..143> is AI SENSE 3; the reference for each AI <144..207> is AI SENSE 4.

AO <0,1>

AO GND

Analog Output Channels—These terminals supply voltage output.

AO GND

—

Analog Output Ground—AO GND is the reference for AO. All ground references—AI GND, AO GND, and D GND—are connected on the device. Though AI GND, AO GND, and D GND are connected on the device, they are connected by small traces to reduce crosstalk between subsystems. Each ground has a slight difference in potential.

D GND

—

Digital Ground—D GND supplies the reference for port 0, port 1, port 2 digital channels, PFI, and +5 V. All ground references—AI GND, AO GND, and D GND—are connected on the device. Though AI GND, AO GND, and D GND are connected on the device, they are connected by small traces to reduce crosstalk between subsystems. Each ground has a slight difference in potential.

P0.<0..31>

D GND

Port 0 Digital I/O Channels—You can configure each signal individually as an input or output.

APFI 0

AO GND or AI GND

Analog Programmable Function Interface Channels—Each APFI signal can be used as AO external reference inputs for AO, or as an analog trigger input. APFI are referenced to AI GND when they are used as analog trigger inputs. APFI are referenced to AO GND when they are used as AO external offset or reference inputs.

+5 V

D GND

+5 V Power Source—These terminals provide a fused +5 V power source.

PFI <0..7>/P1.<0..7>, PFI <8..15>/P2.<0..7>

D GND

Programmable Function Interface or Digital I/O Channels—Each of these terminals can be individually configured as a PFI terminal or a digital I/O terminal.

As an input, each PFI terminal can be used to supply an external source for AI, AO, DI, and DO timing signals or counter/timer inputs. As a PFI output, you can route many different internal AI, AO, DI, or DO timing signals to each PFI terminal. You can also route the counter/timer outputs to each PFI terminal. As a port 1 or port 2 digital I/O signal, you can individually configure each signal as an input or output.

AI Absolute Accuracy Equation

AbsoluteAccuracy = Reading · (GainError) + Range · (OffsetError) + NoiseUncertainty

  • GainError = ResidualGainError + GainTempco · (TempChangeFromLastInternalCal) + ReferenceTempco · (TempChangeFromLastExternalCal)
  • OffsetError = ResidualOffsetError + OffsetTempco · (TempChangeFromLastInternalCal) + INLError
  • NoiseUncertainty =

    for a coverage factor of 3 σ and averaging 10,000 points.

AI Absolute Accuracy Example

Absolute accuracy at full scale on the analog input channels is determined using the following assumptions:

  • TempChangeFromLastExternalCal = 10 °C
  • TempChangeFromLastInternalCal = 1 °C
  • number_of_readings = 10,000
  • Coveragefactor = 3 σ

For example, on the 10 V range, the absolute accuracy at full scale is as follows:

  • GainError = 48 ppm + 13 ppm · 1 + 1 ppm · 10 = 71 ppm
  • OffsetError = 13 ppm + 21 ppm · 1 + 60 ppm = 94 ppm
  • NoiseUncertainty =
    315⁢ μV⁢  ⋅  310,000
    = 9.4 µV
  • AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty = 1, 660 µV

AO Absolute Accuracy Equation

  • AbsoluteAccuracy = OutputValue · (GainError) + Range · (OffsetError)
  • GainError = ResidualGainError + GainTempco · (TempChangeFromLastInternalCal) + ReferenceTempco · (TempChangeFromLastExternalCal)
  • OffsetError = ResidualOffsetError + OffsetTempco · (TempChangeFromLastInternalCal) + INLError

AI Absolute Accuracy Example

  • TempChangeFromLastExternalCal = 10 °C
  • TempChangeFromLastInternalCal = 1 °C
  • number_of_readings = 10,000
  • Coveragefactor = 3 σ

For example, on the 10 V range, the absolute accuracy at full scale is as follows:

  • GainError = 48 ppm + 13 ppm · 1 + 1 ppm · 10 = 71 ppm
