Synopsis:

The course is dedicated to principle, properties and applications of selected special measuring instruments. It deals mainly with calibrators and other sources of calibration signals, devices for measurement of extremely low voltage and current signals, lock-in amplifiers, power analyzers and electronic loads, devices used for EMC measurements, real-time spectrum analyzers, metallic and optical reflectometers and radio testers (Bluetooth, NMT, GSM, UMTS). A special part is devoted to sampling measurement methods and virtual instrumentation.
