Chapter III Horizontal System

3.1 Horizontal control

(1) Horizontal control knob
Using the horizontal control knob can change the horizontal scale (time base) and
trigger horizontal position (trigger position) in internal storage. The vertical midpoint in
screen horizontal direction is the time reference point of waveform. Changing of horizontal
scale can lead to expansion or shrink of waveforms relative to screen center. When the
horizontal position changes, the position relative to waveform trigger point will be
changed.
The horizontal system can be controlled by the following panel buttons/knobs.
The horizontal position control knob is use to adjust the horizontal position of channel
waveform (including mathematical operation). The resolution of the horizontal position
control knob varies at different time base.
Horizontal scale control knob is use to change the time base of the channel waveform,
by shown as s/div. If the extension time base is being turn on, the window width will be
changed by due to the delay scanning time base through turning the horizontal scale
knob.
(2) Horizontal menu button
user can press to enter the horizontal menu function. (See table below)
