“In a nutshell,” said Wolfgang Schmittseifer, CEO of Rohde & Schwarz, “the personal computer completely changed test equipment of all kinds. Not only the way test equipment is designed and manufactured, but the way users interact with it, and the number of measurements it can perform have been vastly improved thanks to the PC,” he explained. “This technology enables cost-effective, compact, powerful instruments to be created that simply could not be realized otherwise.”
LabVIEW enables a range of users with minimal or no programming skills to quickly configure measurement icons and virtual test systems.
Virtual Instruments
Over the past 30 years, a change in the science of measurement has happened with the migration from analog to digital instrumentation. According to Martyn Etherington, vice systems were isolated islands of technology.”
Two other trends in the evolution of the PC also affected measurement instrumentation: increased computing power, and lower prices. According to Rae, “The availability of powerful microprocessors, memory chips, and digital signal processors (DSPs), combined with computing power, enabled customers to get more capability at a lower price. These changes continue to be felt down to the present day.”
