range The maximum and minimum parameters between which a sensor,
instrument, or device operates with a specified set of characteristics. This
may be a voltage range or a frequency range.
real time 1. Displays as it comes in; no delays.
2. A property of an event or system in which data is processed and acted
3. Pertaining to the performance of a computation during the actual time
RSE Referenced Single-Ended configuration—All measurements are made with
respect to a common reference measurement system or a ground. Also
called a grounded measurement system.
RTSI bus Real-Time System Integration bus—The National Instruments timing bus
that connects DAQ devices directly, by means of connectors on top of the
devices, for precise synchronization of functions.
S
s Seconds.
S Samples.
SCC Signal Conditioning Carriers—A compact, modular form factor for signal
conditioning modules.
SCXI Signal Conditioning eXtensions for Instrumentation—The National
Instruments product line for conditioning low-level signals within an
external chassis near sensors so that only high-level signals are sent to DAQ
devices in the noisy PC environment.
sensor A device that responds to a physical stimulus (heat, light, sound, pressure,
motion, flow, and so on), and produces a corresponding electrical signal.
Primary characteristics of sensors are sensitivity, frequency range, and
linearity.
