The waveform before enlargement:
The waveform in the area that has not been covered by the subtransparent blue in
the upper part of the screen is the waveform before enlargement. You can turn
HORIZONTAL POSITION to move the area left and right or turn
HORIZONTAL SCALE to enlarge or reduce this area.
The waveform after enlargement:
The waveform in the lower part of the screen is the horizontally expanded waveform.
Note: the delayed time base has increased its resolution relative to the main time
base (as shown in the figure above). The delayed time base should be less than or
equal to the main time base.
Tip
When the channel is currently CH1-CH4, you can enter the delayed sweep not only
through MENU operation in the horizontal area but also by directly pressing
HORIZONTAL SCALE (delayed sweep shortcut key) to switch to the delayed
sweep mode.
