Figure 3-10 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.
