X-Y Format 
 
This format is useful for studying phase relationships between CH1 and ch2 (CH3 
and CH4 can’t be used).CH1 in the horizontal axis(X) and CH2 in the vertical axis(Y), 
the oscilloscope uses a none-trigger acquisition mode, data is displayed as dots. 
 
Press MENU→Time Base→X-Y to enter X-Y mode.

The oscilloscope can acquire waveforms with any sampling rate in Y-T mode (up to 
2GSa/s for single channel or half channel 
[1]
). But in X-Y mode, up to 1GSa/s can be 
used and the default is 250MSa/s. Generally, the lower the sample rate is, the better 
the Lissajous graphic will be. 
NOTE [1]: Half channel indicates selecting one of the channels in CH1 and CH2, or in CH3 and 
CH4. 
 
The following modes or functions will not work in X-Y format.
