Vertical Control
You can control the vertical position and scale of the selected waveform using
the vertical menu and knobs.
To Change Vertical Scale and Position
By changing the vertical scale, you can focus on a particular portion of a
waveform. By adjusting the vertical position, you can move the waveform up or
down on the display. That is particularly useful when you are comparing two or
more waveforms.
If you want the POSITION knob to move faster, press the SHIFT button. When
the light next to the SHIFT button is on and the display says Coarse Knobs in
the upper right corner, the POSITION knob speeds up significantly.
To Check the Vertical Scale
Check the Vertical readout at the bottom-left part of the display for the volts/di-
vision setting of each displayed channel (the selected channel is in inverse
video). (See Figure 3–67.)
To Change Vertical Parameters
Use the Vertical menu (see Figure 3–67) to select the coupling, bandwidth, and
offset for the selected waveform. This menu also lets you numerically change the
position or scale.
