SCXI-1125 User Manual
Data acquisition—(1) collecting and measuring electrical signals from
sensors, transducers, and test probes or fixtures and inputting them to a
computer for processing; (2) collecting and measuring the same kinds of
electrical signals with A/D and/or DIO boards plugged into a computer, and
possibly generating control signals with D/A and/or DIO boards in the
same computer.
A device that collects signals for data acquisition devices. Examples are
MIO and 1200 boards.
decibel—The unit for expressing a logarithmic measure of the ratio of
two signal levels: dB = 20 log
direct current
A plug-in data acquisition board, module, card, or pad that can contain
multiple channels and conversion devices.
An input circuit that actively responds to the difference between two
terminals, rather than the difference between one terminal and ground.
