To Turn Delayed Sweep On/Off 
 
Delayed sweep can be used to enlarge a length of waveform horizontally to view the 
waveform details. 
Note: Delayed sweep can only be turned on when the current time base mode is 
“Y-T” and the “Pass/Fail” test is off. 
 
Press MENU in the horizontal control area (HORIZONTAL) and press Delayed to 
turn delayed sweep (the default is off) on or off. You can also press HORIZONTAL 
  SCALE to quickly switch the on/off status of the delayed sweep.  
 
When delayed sweep is turned on, the screen is divided into two display areas as 
shown in the figure below. The waveform of normal sweep is displayed in the upper 
part of the screen and its horizontal time base (called main time base) is displayed at 
the upper-left side of the screen. The delayed sweep waveform (the horizontally 
expanded waveform) is displayed in the lower part of the screen, its horizontal time 
base (called delayed sweep time base) is displayed at the middle of the screen and 
its horizontal position (called delayed sweep horizontal position) is displayed at the 
upper-right side of the screen. At this point, HORIZONTAL 
  SCALE is used to 
adjust the delayed sweep time base; HORIZONTAL 
  POSITION is used to 
adjust the delayed sweep horizontal position.
