Acquiring and Displaying Waveforms
TDS 684A, TDS 744A, & TDS 784A User Manual
3–11
As you turn the vertical SCALE knob clockwise, the value decreases
resulting in higher resolution because you see a smaller part of the wave-
form. As you turn it counterclockwise the scale increases allowing you to see
more of the waveform but with lower resolution.
2. Turn the vertical POSITION knob. Again, note that only the selected
waveform changes position.
3. To make positioning faster, press the SHIFT button. When the light above
the SHIFT button is on and the display says Coarse Knobs in the upper
right corner, the POSITION knob positions waveforms more quickly.
The POSITION knob simply adds screen divisions to the reference point of
the selected waveform. Adding divisions moves the waveform up and
subtracting them moves the waveform down. You also can adjust the
waveform position using the offset option in the Vertical menu (discussed
later in this section).

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. Adjustment of vertical position is particularly useful when
you are comparing two or more waveforms.
