Utilization of the hardware to create an autonomous, universal measurement system with Ethernet interface and operating system on board, in order to enable on-fly reconfiguration accordingly to the user’s needs. Creation of TCP/IP and web-based control interface. Acquisition in dangerous places (i.e. high energy physics) Acquisition in places which are difficult to access Reconfigurable measurement system Digital oscilloscope The goal of the project
