YT dual window display mode
XY mode
In this mode, the oscilloscope converts the two input channels from voltage-time dis-
play to voltage-voltage display. The X-axis Y-axis combination can be CH1-CH2 or
CH3-CH4. The Lissajous method can conveniently measure the phase difference be-
tween two signals at the same frequency. The figure below shows the measurement
principle of phase difference.
