2.10.1 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
display format to XY.
The table below shows how to operate some controls in XY format.

2.11 Measure System
The oscilloscope can use scale and cursor for measurement or automatic measurement, so that
users can fully understand the measured signals.
2.11.1 Scale measurement
By using the method, estimation can be made quickly and intuitively. For instance, waveform
amplitude can be observed, and a probable measurement result is judged according to the vertical
scale. The method realizes simple measurement by multiplying the vertical scale number of the
signal with the vertical gear Volt/div.
2.11.2 Cursor measurement
[CURSORS] is a function key for cursor measurement.
