Summary

The course is focused on electronic measurement using modern measurement instruments and using their special functions. The basic blocks of the measurement system are described in detail with regard to their static and dynamic properties as well as the minimization of measurement errors. Practical problems are explained and demonstrated methods of measurement of basic quantities from the design of proper sensors to data processing and evaluation. Students are acquainted with both classical measurement instruments and especially with modern functions of these devices, which enable real-time decoding of serial buses, FFT analysis, etc. In the course of lectures and exercises students are also familiarized with the field of Industry 4.0 and IoT from the point of view of realization of the measurement chain with a view to minimizing energy demand and choosing methods of wireless data transmission and processing. Here are presented and demonstrated basic technologies such as LoRa, SigFox, IQRF. Students are also acquainted with the basic concepts of electromagnetic compatibility and modern instrumentation, including examples of methods of measurement of radiated interference, are demonstrated.
