Learning outcomes:
After successfully completing this course, students will be: - able to calculate the root-mean-square value of any time-dependent quantity, - able to determine undulating currents and voltages from the separate measurement of zero frequency and periodic quantities, - familiar with the definitions for mean value, rectified value, root-mean-square value, form factor and peak factor and be able to explain their meaning. - able to identify the problems that can arise from the use of certain measuring elements/instruments in connection with the measurement of time-varying electrical quantities and take them into account in measurements, - able to calculate field and performance quantities in the pseudo-units Bel, Decibel and Neper forward and backward, - able to calculate with quantities in the above-mentioned pseudo-units,
 - able to outline the basic structure of a spectrum analyzer and outline the significance of its individual components, - able use the basic functions of a spectrum analyzer, including the appropriate selection and adjustment of e.g. the center frequency and frequency range, the vertical resolution, the resolution bandwidth, the discriminator, the video bandwidth, - able to safely use instrument transformers for current and voltage measurements and quantify their measurement errors, - able to measure or calculate unknown AC resistances using various AC bridges and/or oscilloscopes, - able to calculate loss factors and qualities of alternating current resistances and identify them by way of measurement, - able to explain how modern LCR meters work, - able to to determine the mutual inductance of two coupled coils by measurement, - able to carry out power measurements (apparent, reactive and active power) in a single- and three-phase system (with or without neutral conductor), -  able to calculate the power in corresponding single-phase and three-phase networks, - able to describe how a Ferraris meter works, - able to name, compare and roughly evaluate common methods of temperature measurement and their mode of operation to ascertain which method is suitable for a specific purpose, - able to measure static magnetic fields using a field coil and integrator (strength and direction), - able to use acceleration sensors to measure inclination and rotational speed, - able to calibrate sensors, - able to interpret their measurement results and explain the corresponding calculations. - able to independently plan, organize and carry out measurement tasks in small groups, - able to operate more complex measuring equipment,

Teaching methods/Media:
Slides, lab guides, exercises and videos; all materials can be accessed electronically by students. The module combines lecture and lab components. The lab component consists of 5 compulsory sessions. Experiments will be carried out in groups of two, preparation for the lab sessions will be checked individually. A report must be written for each of the lab experiments. These reports must be personally presented to the lecturer/supervisor. In the lab sessions, students will carry out various measuring tasks on real objects and devices without demonstration, but according to instructions. A supervisor will be available to assist them, if needed.
