To Adjust the Horizontal Time Base

Horizontal time base, also called the horizontal scale, refers to the time of each grid

in the horizontal direction of the screen. It is usually expressed in s/div. The

adjustable range of the horizontal time base is related to the model type.

While you change the horizontal time base, the displayed waveforms of all channels

are expanded or compressed horizontally relative to the current selected horizontal

reference baseline (refer to "Horizontal Expansion"). The horizontal time base at

the upper-left corner of the screen will be changed accordingly, as shown in the

figure below.

You can adjust the horizontal time base with the following three methods:

 Rotate Horizontal

SCALE to adjust the horizontal time base within the

available range (clockwise to reduce the horizontal time base and

counterclockwise to increase).

 Enable the touch screen function and adjust the horizontal time base with the

pinch & stretch gesture on the touch screen. For details, refer to the "Pinch &

Stretch" section.

 Enable the touch screen function, and tap the horizontal time base label

at the top of the screen. The following window is displayed. Tap the

icon at the right side of the Scale input field to decrease or increase

the horizontal scale. You can also tap the Scale input field to input a specific

value with the displayed numeric keypad.

In the Horizontal control area (Horizontal), rotate the Horizontal

SCALE knob

to switch the adjustment mode between "Coarse" and "Fine" (by default, it is Coarse).

You can also press Acquire  Fine to enable or disable the fine adjustment of the

horizontal time base.

 Coarse adjustment: Rotate the Horizontal SCALE knob will adjust the

horizontal time base of the waveforms of all channels at 1-2-5 step within the

adjustable range. Rotate it clockwise to reduce the horizontal time base, and

counterclockwise to increase the horizontal time base.

 Fine adjustment: Rotate the Horizontal SCALE knob will adjust the

horizontal time base of the waveforms of all channels with a minor step value

within the adjustable range. Rotate it clockwise to reduce the horizontal time
