5.1.1 XY Format
The XY format is used to analyze phase differences, such as those represented by Lissajous
patterns. The format plots the voltage on CH1 against the voltage on CH2, where CH1 is the
horizontal axis and CH2 is the vertical axis. The oscilloscope uses the untriggered Normal
acquisition mode and displays data as dots. The sampling rate is fixed at 1 MS/s.
The oscilloscope can acquire waveforms in YT format at any sampling rate. You may view the
same waveform in XY format. To perform this operation, stop the acquisition and change the
