 Introduction to Data Acquisition (DAQ)
The simplest way to store data is to record it on paper with either a strip-chart recorder or an x-y plotter.
For greater utility, most modern analytical instruments digitize data in digital format for subsequent data storage, analysis, and presentation.
For some types of instruments, such as Fourier-transform-based spectrometers, digitized data is necessary for the data manipulation to extract the spectrum from the raw data.
