Introduction to the Vertical System
As shown in Figure 4-11, there are a few of buttons and knobs in VERTICAL
CONTROLS. The following practices will gradually direct you to be familiar with
the using of the vertical setting.
Figure 4-11 Vertical Control Zone
1. Use the "VERTICAL POSITION" knob to show the signal in the center of the
waveform window. The "VERTICAL POSITION" knob functions the
regulating of the vertical display position of the signal. Thus, when the
"VERTICAL POSITION" knob is rotated, the pointer of the earth datum point
of the channel is directed to move up and down following the waveform.
Measuring Skill
If the channel is under the DC coupling mode, you can rapidly measure the DC
component of the signal through the observation of the difference between the
wave form and the signal ground.
If the channel is under the AC mode, the DC component would be filtered out.
This mode helps you display the AC component of the signal with a higher
sensitivity.
2. Change the Vertical Setting and Observe the Consequent State Information
Change.
With the information displayed in the status bar at the bottom of the waveform
window, you can determine any changes in the channel vertical scale factor.
Turn the vertical "VOLTS/DIV" knob and change the "Vertical Scale Factor
(Voltage Division)", it can be found that the scale factor of the channel
corresponding to the status bar has been changed accordingly.
