To Understand the Vertical System
As shown in Figure 1-8, there are several buttons and knobs in the VERTICAL
control area, which are used for setting Channels, MATH and REF functions as well as
adjusting vertical position and Volts/div of waveforms. In addition, different colors
are designed for different channels, corresponding to different waveforms, so as to
observe clearly.
