GPIB TUTORIALBACKGROUNDInstrumentation has always leveraged off widely used electronics technology to drive itsinnovation. The jeweled movement of the clock was first used to build analog meters. The variablecapacitor, the variable resistor, and the vacuum tube from radios were used to pioneer the firstelectronic instruments. Display technology was leveraged off the television for use in oscilloscopesand analyzers. Today, cost-effective and powerful desktop and notebook computers are paving the way for newtypes of instruments --virtual instruments--. Virtual instruments are designed and built by the userto match specific needs by leveraging off the power and low cost of PCs and workstations. Software is the key to virtual instruments. Application software empowers the user with the toolsnecessary to build virtual instruments and expand their functionality by providing connectivity tothe enormous capabilities of PCs, workstations, and their assortment of applications, boostingperformance, flexibility, reusability and reconfigurability while diminishing at the same timedevelopment and maintenance costs.
