Expand by Ground/Center 
Background 
When the voltage scale is changed, the Expand 
function designates whether the signal expands 
from the center of the signal or from the signal 
ground level. Expand by center can be used to 
easily see if a signal has a voltage bias. Expand by 
ground is the default setting. 
Panel operation 
1.  Press a channel key. 
2.  Press Expand repeatedly to toggle 
between expand By Ground and 
Center. 
Range 
By Ground, By Center 
Example 
If the vertical scale is changed when the Expand 
function is set to ground, the signal will expand 
from the ground level*. The ground level does not 
change when the vertical scale is changed. 
If the vertical scale is changed when the Expand 
function is set to center, the signal will expand 
from the center of the signal. The ground level will 
suit to match the signal position. 
*Or from the upper or lower edge of the screen if 
the ground level is off screen.
