NI-DAQmx 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.

NRSE Non-Referenced 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.

OEM Original Equipment Manufacturer.

offset The unwanted DC voltage due to amplifier offset voltages added to a

signal.

PCI 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.

PGIA Programmable gain instrumentation amplifier.

physical channel See channel.

PXI PCI eXtensions for Instrumentation—PXI is an open specification that

builds off the CompactPCI specification by adding

instrumentation-specific features.

RSE Referenced single-ended mode—all measurements are made with respect

to a common reference measurement system or a ground. Also called a

grounded measurement system.
