2.9.1 X-Y mode
Use the XY format to analyze phase difference. At the format, the voltage of channel 1
determines coordinate X (horizontal) of a point, while the voltage of channel 2
determines coordinate Y (vertical) of the point. The oscilloscope uses a non-triggered
sampling mode to display the data as a spot. Figure 2-48 shows the YT mode, and it
shows that signals of the two channels have the same amplitude and frequency and
the phase difference is 90 degrees. After switching to X-Y mode, the waveform is
shown in figure 2-49 below.
