setting.
Figure 3-11 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.
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.
