a) Firstly calibrate the Oscilloscope to provide a rough view of the signal as in the first example (possible using
Autoset), then set the parameters as indicated above.
On electrical power distribution networks we regularly seek to observe possible harmonic distortion phenomena,
which often cause problems for the global operation of the installation and the instruments connected.
This example realistically simulates a sinusoidal 50Hz signal (network frequency of many countries), on which
harmonic ranks have been superimposed in the following manner:
Amplitude sinus 0.3V (10%); frequency 150Hz (rank 3); dephasing: PI (180°)
Amplitude sinus 0.6V (18%); frequency 250Hz (rank 5); dephasing: PI/2 (90°)
Important: in order that the dephasing measurements indicated may be correct, the channel coupling must
imperatively be set to DC.
