Introduction to the Vertical System
, there are a few of buttons and knobs in
Vertical Controls
.
The 4 channels are marked by different colors which are also used to mark both the
corresponding waveforms on the screen and the channel input connectors. Press one
of the channel buttons to open the corresponding channel menu, and press again to
turn off the channel.
Press the
Math
button to display the math menu in the bottom. The pink M waveform
appears on the screen. Press again to turn off the math waveform.
The 4 channels use the same
Vertical Position
and
Vertical Scale
knobs. If you want
to set the vertical scale and vertical position of a channel, please press CH1, CH2,
CH3 or CH4 at first to select the desired channel. Then turn the
Vertical Position
and
Vertical Scale
knobs to set the values.
Figure 3-10 Vertical Control Zone
The following practices will gradually direct you to be familiar with the using of the
vertical setting.
1.
Press CH1, CH2, CH3 or CH4 to select the desired channel.
2.
Use the
Vertical Position
knob to show the selected channel waveform in the center
of the waveform window. The
Vertical Position
knob functions the regulating of the
vertical display position of the selected channel waveform. Thus, when the
Vertical
Position
knob is rotated, the pointer of the earth datum point of the selected channel
is directed to move up and down following the waveform, and the position message at
the center of the screen would change accordingly.
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.
