Delayed Sweep
Delayed sweep can be used to enlarge a length of waveform horizontally to view
waveform details.
Press MENU in the horizontal control area (HORIZONTAL) at the front panel and
press Delayed to enable or disable delayed sweep.
Note: To enable delayed sweep, the current time base mode must be "YT".
In delayed sweep mode, the screen is divided into two display areas as shown in the
figure below.

The waveform before enlargement:
The waveform in the area that is not covered by 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.
Compared to the main time base, the delayed time base has increased the waveform
resolution (as shown in the figure above).
Note: The delayed time base should be less than or equal to the main time base.
