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.
The analog bus where SCXI analog signals are routed.
A serial clock signal used to synchronize digital data transfers over the SER
DAT IN and SER DAT OUT lines.
serial data input signal
serial data out to cabled DAQ device
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.
The time required for an amplifier, relays, or other circuits to reach a stable
mode of operation.
See autozero.
The method of calibrating the gain of strain-gauge data acquisition channel
by placing a resistor of known value in parallel with a bridge element.
The manipulation of signals to prepare them for digitizing.
The first slot in a VXI or SCXI system.
The relative deformation of an object subjected to stress. Hence, strain is
dimensionless.
synchronization pulse for scanning
A measure of the amount of noise seen by an analog circuit or an ADC
when the analog inputs are grounded.
