The latest NI-DAQ driver with new VIs, functions, and development
tools for controlling measurement devices. The advantages of
NI-DAQmx over earlier versions of NI-DAQ include the DAQ
Assistant for configuring channels and measurement tasks for your
device for use in LabVIEW, LabWindows/CVI, and Measurement
Studio; increased performance such as faster single-point analog I/O;
and a simpler API for creating DAQ applications using fewer
functions and VIs than earlier versions of NI-DAQ.
An undesirable electrical signal. Noise comes from external sources
such as the AC power line, motors, generators, transformers,
fluorescent lights, CRT displays, computers, electrical storms,
welders, radio transmitters, and internal sources such as
semiconductors, resistors, and capacitors. Noise corrupts signals you
are trying to send or receive.
Nonreferenced single-ended mode—all measurements are made with
respect to a common (NRSE) measurement system reference, but the
voltage at this reference can vary with respect to the measurement
system ground.
Peripheral Component Interconnect—a high-performance expansion
bus architecture originally developed by Intel to replace ISA and
EISA. It offers a theoretical maximum transfer rate of 132 Mbytes/s.
Pull-down.
Programmable function interface.
Programmable gain instrumentation amplifier.

1. A communications connection on a computer or a remote controller.
2. A digital port consisting of four or eight lines of digital input and/or
output.
