MSO4000/DS4000 provides an independent vertical control system for each analog
input channel.

CH4
: analog input channel switches.
The four channels are marked by different colors which are also used to mark
the corresponding waveforms on the screen and the channel input connectors.
Press any key to turn on the corresponding channel and open the corresponding
channel menu; press again to turn off the channel.
VERTICAL
POSITION
: channel vertical position knobs.
Turn the knob to modify the vertical position of the corresponding channel
waveform. During the modification, the waveform of the corresponding channel
moves up and down; the vertical position information (as shown in the figure
below) pops up at the lower-left side of the screen in real-time. Pressing down
the knob can quickly reset the vertical position (zero).
VERTICAL
SCALE
: channel vertical scale knobs.
Turn the knob to modify the vertical scale of the corresponding channel
waveform. During the modification, the waveform of the corresponding channel
is expanded or compressed vertically (the actual amplitude keeps unchaged);
the vertical scale information (as shown in the figure below) at the bottom of the
