To set the Horizontal system

The

HORIZONTAL CONTROLS

includes the

HORIZONTAL MENU

button and

such knobs as

HORIZONTAL POSITION

and

SEC/DIV

HORIZONTAL POSITION knob: this knob is used to adjust the horizontal
positions of all channels (include those obtained from the mathematical
manipulation), the analytic resolution of which changes with the time base.

SEC/DIV knob: it is used to set the horizontal scale factor for setting the main
time base or the window.

HORIZONTAL MENU button: Press this button to active TIME MODE shown
as below with description of each function. (see Fig.26).
