SCXI Quick Start Guide

Measurement System Overview

Figure 1 depicts the measurement system overview, showing the path of 
real-world physical phenomena to your measurement application. Signal 
conditioning components use sensors and transducers to measure signals 
analyzed and presented through application software.
