NI 6132/6133 Specifications

This document lists the I/O terminal summary and specifications for the NI 6132/6133.
For the most current edition of this document, refer to ni.com/manuals. Refer to the DAQ Getting Started Guide for more
information about accessing documents on the NI-DAQ CD.

Note With NI-DAQmx, National Instruments has revised its terminal names so they are easier to understand and
more consistent among NI hardware and software products. The revised terminal names used in this document are
usually similar to the names they replace. For a complete list of Traditional NI-DAQ terminal names and their
NI-DAQmx equivalents, refer to the Terminal Name Equivalents table in the S Series Help.

1 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 = 100
CoverageFactor = 3 σ
For example, on the 10 V range, the absolute accuracy at full scale is as follows:
GainError = 151 ppm + 25 ppm · 1 + 5 ppm · 10 GainError = 226 ppm
OffsetError = 47 ppm + 39 ppm · 1 + 122 ppm OffsetError = 208 ppm

NoiseUncertainty = ------------------------------
1,080 μV ⋅ 3- NoiseUncertainty = 320 μV

AbsoluteAccuracy = 10 V · (GainError) + 10 V · (OffsetError) + NoiseUncertainty AbsoluteAccuracy = 4,660 μV
2 Sensitivity is the smallest voltage change that can be detected. It is a function of noise.
