In order to gain an overview of the actual market situation of semi-professional measurement equipment, a state-of-the-art research was performed. The results of this analysis should provide some basic knowledge of how measurement devices are implemented. Those devices, for example a Universal Serial Bus (USB)-connected oscilloscope, are significantly cheaper and smaller than professional equipment. In general they need some external hardware, like a Personal Computer (PC), to output the measurement results. Only a few of them features a built-in display.
The results of the state of the art research showed a total of about 40 different projects or products, which can be categorized in
The upcoming sub-chapters will briefly describe some of the found projects and lists their specifications and pricing.
