Laboratory for electronic measuring systems (EMS)

The laboratory for electronic measurement systems provides students with a practical insight into current issues in electrical measurement technology, sensor technology and analog and digital signal processing. One focus is on computer-aided measurement and testing systems and the development of suitable electronic hardware and software solutions. On the one hand, this concerns the design of sensors and electronics for analog signal processing and, following a corresponding analog-to-digital conversion, the implementation of software algorithms for digital signal processing on the other.

The software tools MATLAB and Simulink (The MathWorks) are used with various toolboxes (e.g. Instrument Control, Data Acquisition, Signal Processing, DSP System, MATLAB / Simulink Coder) for the following purposes:

• Design and simulation of analog signal processing components, e.g. amplifier and filter circuits
• Implementation of digital signal processing algorithms
• Control and readout of measuring devices via corresponding interfaces
• Realization of "instrumented computers" with data acquisition hardware
• Creation of graphical user interfaces (GUI)
• Model-based software design
• Code generation and execution on target hardware

On the hardware side, various power supplies, function generators, multimeters, oscilloscopes, analyzers, compact USB-based data acquisition devices (e.g. Analog Devices Active Learning Modules) and microcontroller development boards with DSP functionality are available, all of which can be remotely controlled and read out or programmed via MATLAB using a computer. This enables students to create, configure and use their own computer-aided measurement and test systems for automated measurement data acquisition and evaluation.

The laboratory is currently (2020) under construction, so that the equipment of the workstations in particular will be further expanded in the future.
