Figure 1-10 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.
Vertical offset back to 0 shortcut key
Turn the Vertical Position knob to change the vertical display position of channel and push
the position knob to set the vertical display position back to 0 as a shortcut key, this is
especially helpful when the trace position is far out of the screen and want it to get back to the
screen center immediately.
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 Scale 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.
 Push buttons of CH1, CH2 and Math, the operation menu, symbols, waveforms and scale
factor status information of the corresponding channel will be displayed in the screen.
Introduction to the Horizontal System
Shown as Figure 1-11, 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
