PCI eXtensions for Instrumentation—PXI is an open specification that
builds off the CompactPCI specification by adding
instrumentation-specific features.
Root mean square.
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.
Real-Time System Integration—the National Instruments timing bus
that connects DAQ devices directly, by means of connectors on top of
the devices, for precise synchronization of functions.
Seconds.
Samples.
Samples per second—used to express the rate at which a digitizer or
D/A converter or DAQ device samples an analog signal.
Controls how often a scan is initialized; is regulated by the AI SAMP
signal.
Reciprocal of the scan interval.
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. SCXI is an open standard
available for all vendors.
A device that responds to a physical stimulus (heat, light, sound,
pressure, motion, flow, and so on) and produces a corresponding
electrical signal.
The amount of time required for a voltage to reach its final value
within specified limits.
The manipulation of signals to prepare them for digitizing.
