Synopsis:

The evaluation of the principal values determining the quality of the passive and active devices. Measuring methods, their evaluation , identification of systematic faults. The description of the tested device, two ports parameters of the device. Matching of the device to the measuring circuit. The noise of the electronic circuits, optimal noise and power matching. Non-linearity of the „linear“ circuits, intermodulation distortion, measuring of the non-linearity and intermodulations.
