Oscilloscope R eference Scaling and positioning
Scaling and positioning
The scaling and positioning controls determine the portion of the input signal received by the acquisition
system. Set vertical scaling, positioning, and DC offsets to display the features of interest on your
waveform and
to avoid clipping.
Waveform data outside of the vertical acquisition window is clipped; that is, the data is limited to the
minimum or m
aximum boundaries of the vertical acquisition window. This causes inaccuracies in
amplitude-related measurements. For more information see Vertical Acquisition Window Considerations
(see page 681).
Acquired waveform
Adjusted horizontal scale
xxx
Set the horizontal scale, position, and resolution (record length) to include the acquired waveform record
waveform attributes of interest with good sampling density on the waveform. T
hese settings define the
horizontal acquisition window, described in Horizontal Acquisition Window Considerations
(see page 684).
NOTE. The terms vertical acquisition window and horizontal acquisition window refer to the vertical
and horizontal range of the segment of the input signal that the acquisition system acquires. The terms
do not refer to any display windows on screen.

Vertical Acquisition Window considerations
You can set the vertical scale, position, and offset of each channel independently of other channels.
Vertical scale and offset specify the vertical acquisition window for each channel. Parts of the signal
amplitude that fall within the vertical window are a cquired; parts outside (if any) are not.
