X-Y Mode 
 
In this mode, the X axis and Y axis both represents voltage. The oscilloscope 
automatically turns on all the four channels (CH1 to CH4) and the screen is divided 
into two cursor areas (XY1 and XY2). In XY1 area (at the left of the screen), the X 
axis and Y axis track the voltages of CH1 and CH2 respectively; in XY2 area (at the 
right of the screen), the X axis and Y axis track the voltages of CH3 and CH4 
respectively. 
 
The X-Y time base mode can be used to test the phase variation of a signal when it 
passes through a circuit network. Connect the oscilloscope with the circuit and 
monitor the input and output signals of the circuit. 
 
Note:   
  In this mode, the “To Adjust the Horizontal Position”, “To Turn Delayed 
Sweep On/Off”, “To Specify the Acquisition Mode”, “Trigger”, “To Make 
Math Operation”, “To Make One-key Measurement”, “To Specify the 
Measurement Range”, “Logic Analyzer”, “Protocol Decoding”, 
“Reference Waveform”, “Pass/Fail Test”, “Waveform Recording” and 
“Vectors” are not available.  
  The “X-Y” cursor mode (refer to “X-Y Mode”) is only available in this time base 
mode.  
  If delayed sweep is currently turned on, when the “X-Y” mode is turned on, the 
delayed sweep will be turned off automatically. When the “Y-T” mode is turned 
on again, the delayed sweep will be turned on automatically.
