The waveform before enlargement:  
The waveform of normal sweep is displayed in the upper part of the screen. Wherein, 
the waveform in the area (called the enlargement area) that has not been covered by 
subtransparent blue is the waveform before enlargement (correspond to the 
waveform after enlargement displayed in the lower part of the screen). You can turn 
HORIZONTAL 
  POSITION to move the enlargement area left or right or turn 
HORIZONTAL 
  SCALE to enlarge or reduce the enlargement area. 
 
Note: To modify the horizontal time base of normal sweep (namely, the main time 
base), delayed sweep should be turned off. After setting the desired main time base 
by turning HORIZONTAL 
  SCALE, turn on delayed sweep. 
 
The waveform after enlargement: 
The delayed sweep waveform in the lower part of the screen is the enlarged 
waveform (the horizontally expanded waveform). It corresponds to the waveform 
before enlargement in the upper part of the screen. Compared to the main time base,
