A hierarchical instrumentation taxonomy is accordingly described as illustrated by discrete automatic test equipment remote measurement environments automation system virtual instruments and analytical instrumentation for aiding sensed-feature understanding. The integration of each of these instrumentation categories is also defined by bus and network structures appropriate for meeting application performance requirements. Chapter highlights include the description of virtual instrument capabilities for elevating fundamental sensor data to a higher attribution enabling more complex cognitive interpretation. Such attribution is then extended to analytical instrumentation employing hyperspectral sensing of multiple spatial and spectral data for improved feature characterization. This is shown to be useful in advanced process control systems for comparing product states to goal states during manufacturing for the purpose of synthesizing compensating online quality control references. 9-1 SYSTEM INTEGRATION AND INTERFACE BUSES Electrical measurement has been evolving for nearly two centuries since the invention of the galvanometer in 1820. Continued development has provided an expanding range of sophisticated measurement signal conditioning analysis and data presentation capabilities with the instrumentation taxonomy shown in Figure 9-1 that can accommodate the comprehensive data requirements of advanced hierarchical sensor and actuator systems. Four distinct instrumentation integration structures are defined each of which involve different implementations for meeting their re-
