M Series
An architecture for instrumentation-class, multichannel data acquisition
devices based on the earlier E Series architecture with added new features.
Maxim/Dallas
Semiconductor
1-Wire Protocol
a very simple, low-cost, master-slave serial communication protocol,
requiring that a single master device, such as the data acquisition system,
supply power and initiate each transaction with each node according to a
defined transaction timing sequence, on a single wire and return
measurement
The quantitative determination of a physical characteristic. In practice,
measurement is the conversion of a physical quantity or observation to a
domain where a human being or computer can determine the value.
N
NI-DAQ
National Instruments driver software for DAQ hardware
noise
an undesirable electrical signal—noise comes from external sources such
as the AC power line, motors, generators, transformers, fluorescent lights,
soldering irons, 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.
NRSE
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
