To measure the phase shift you may in different manners the handiest of proceed which is likely to be the following:
- Place the scope on AC channels, trigger on Y2 (input). Carefully for both align the of the vertical position of the tracks with the oscilloscope screen Zero sweep time to display a mid-line (horizontal axis). Select an adequate full wave period Read the period
Read the period (T) in mm and the distance of the zero-crossing points of the input and output waves (L) also in mm.
- Calculate the phase shift in radians as follows:
