Over the years, instrumentation design has benefited from technological advancements, and, simultaneously suffered adverse effects from increasing design complexity. Among these advancements has been the shift from traditional instrumentation, defined by a physical front-panel interface controlled and monitored by the user; to modern instrumentation, which utilize specialized hardware and provide interactive, softwarebased interfaces, from which the user interacts using a general-purpose computer (GPC). The term virtual instrumentation (VI) (Baican & Necsulescu, 2000) is used to describe such systems, which generally use a modular hardware-based stage to process or generate signals, and a GPC to provide the instrument with a layer of reprogrammable software capabilities. A variety of instruments can be emulated in software, limited only by capabilities of the VI’s output stage hardware. In more recent years, the popularity of reconfigurable hardware (Hsiung et al., 2009), more specifically field programmable gate arrays (FPGAs) (Maxfield, 2004), have revolutionized capabilities of electronic instrumentation. FPGAs are complex integrated circuits (ICs) that provide an interface of digital inputs and outputs that can be assembled, using specialized development tools, to create customized hardware configurations. By incorporating FPGA technology into traditional VI, the instrument’s capabilities are expanded to include an additional layer of hardware-based functionality. In this chapter we explore the use of such enhanced instruments, which are further augmented by the use of object-oriented programming techniques and the use of opensource development tools. Using low-cost FPGAs and open-source software we describe a design methodology enabling one to develop state-of-the-art instrumentation via a generalized instrumentation core that can be customized using specialized output stage hardware. Additionally, using object-oriented programming (OOP) techniques and opensource tools, we illustrate a technique to provide a cost-effective, generalized software framework to uniquely define an instrument’s functionality through a customizable interface, implemented by the designer. The intention of the proposed design methodology is to permit less restrictive collaboration among researchers through elimination of proprietary licensing; making hardware and software development freely available while building upon an existing open-source structure. Beginning with section 2, the concept of a
