1. A/D and D/A converters – types, function principles, static and dynamic properties.
2. Measurement of noise, vibration, force, position, and revolutions. Measuring elements: accelerometers, laser vibrometers, measuring microphones, acoustic camera, intensity probes, capacitive and inductive position sensors, tacho probes. Anti-aliasing filtering. FFT and 1/n signal analyzers – octave analysis technique.
3. Signal generators, input excitation signals (unit pulse, broad-spectrum noise, periodic signals, pseudorandom, etc.), electrodynamic exciters, piezoactuators.
4. Frequency analysis and order analysis of rotating and periodically working machines. Measurement of frequency spectra during start-up and run-down of machines.
5. Diagnostics of journal bearings - measurement on the Rotorkit system.
6. Shaft orbits in journal bearings – full spectra, issues of passive and active vibration suppression.
7. Measurement of frequency characteristics, modal analysis, testing of machines and equipment.
8. Life tests, prediction of machine life.
