1.
Use the horizontal
“SEC/DIV”
knob to change the horizontal time base setting and observe the
consequent status information change. Rotate the horizontal “
SEC/DIV
” knob to change the horizontal
t
ime base, and it can be found that the “
Horizontal Time Base
” display in the status bar changes
accordingly. The horizontal scanning speed steps from 2ns up to 100s in the sequence of 1-2-5.

Use the “
HORIZONTAL POSITION
”
knob to adjust the horizontal position of the signal in the waveform
window. The “
HORIZONTAL POSITION
”
knob is used to control the triggering displacement of the signal
or for other special applications. If it is applied to triggering the displacement, it can be observed that the
wave form
moves horizontally with the knob when you rotate the “
Horizontal
Position
” knob.

With the “
HORIZ MENU
” button pushed down, you can set and initiate the Window Expansion.
