Understanding Oscilloscope Functions

Scaling and Positioning Waveforms

You can change the waveform display by adjusting the scale and
position. When you change the scale, the waveform display will
increase or decrease in size. When you change the position, the
waveform will move up, down, right, or left.
The channel reference indicator (located on the left of the graticule)
identifies each waveform on the display. The indicator points to the
reference level of the waveform record.
To view the display area and readouts, refer to page 2- - 2.

Vertical Scale and Position

You can change the vertical position of waveforms by moving them
up or down in the display. To compare data, you can align a
waveform above another or you can align waveforms on top of each
other.
You can change the vertical scale of a waveform. The waveform
display will contract or expand relative to the reference level.
For oscilloscope-specific descriptions, refer to page 2- - 8 in the
Operating Basics chapter and page 9- - 52 in the Reference chapter.

Horizontal Scale and Position; Pretrigger Information

You can adjust the HORIZONTAL POSITION control to view
waveform data before the trigger, after the trigger, or some of each.
When you change the horizontal position of a waveform, you are
actually changing the time between the trigger and the center of the
display. (This appears to move the waveform to the right or left on
the display.)
