National Instruments Corporation
protocol the exact sequence of bits, characters, and control codes used to transf er
data between computers and peripherals through a communications
channel, such as the GPIB bus
pts points
RRAM random-access memory
resolution the smallest signal increment that can be detected by a measurement
system. Resolution can be expressed in bits, in proportions, or in
percent of full scale. For example, a system has 12-bit resolution, one
part in 4,096 resolution, and 0.0244 percent of full scale.
rms root mean square—the square root of the average value of the square of
the instantaneous signal amplitude; a measure of signal amplitude
ROM read-only memory
RTSI bus real-time system integration bus—the National Instruments timing bus
that connects DAQ boards directly, by means of connectors on top of
the boards, for precise synchronization of functions
Ss seconds
Ssamples
sampling rate the rate, in samples per second (S/s), at which each sample in the
waveform buffer is updated
SCXI Signal Conditioning eXtensions for Instrumentation—the National
Instruments product line for conditioning low-level signals within an
external chassis near sensors so only high-level signals are sent to DAQ
boards in the noisy PC environment
