Anotace:

The subject guides students to gain both theoretical and practical skills in

radiofrequency and microwave measurements. It is focused on measurement methods and instruments applied e.g. in telecommunication, radio, radar, cable network, navigation, and other systems working in frequency band from units of MHz to 50GHz, thus from classical radio to microwave area. Students are informed about basic principles and construction of generators, synthesizers, frequency counters, vector generators, spectrum, signal, scalar and vector analyzers and their applications in various measurement methods. Theoretical knowledge from lectures are supplemented by practical measurements in laboratories equipped with modern instruments applied in current professional practice.
