Y -T: Show the relative relation between vertical voltage and horizontal time.
X -Y: Show CH1 value at X axis; CH2 value at Y axis. The XY format is used to analyzer phase
difference, such as those represented by Lissajous patterns. Please refer to 4.3 Section.
X-Y Setting: Users can change X-Coordinate and Y-Coordinate for CH1, CH2, CH3, CH4.

Roll: In Roll Mode, the waveform display updates from right to left.
In Roll mode, the waveform display rolls from right to left. No trigger or horizontal offset control of
