Introduction to the Horizontal System
Shown as Fig. 11, there are a button and two knobs in the "
HORIZONTAL
CONTROLS
". The following practices will gradually direct you to be familiar with
the setting of horizontal time base.
Figure 11.
Horizontal Control Zone.
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 time base, and
it can be found that the "
Horizontal Time Base
" display in the status
bar changes accordingly. The horizontal scanning speed steps from 2 ns
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 "
HORIZONTAL MENU
" button, you can do the Window Setting
and the Window Expansion.
