Live+Store+Diff selection is only available while the test is
running and a Trace is loaded. The differential trace is calculated
between Live and loaded stored traces during the measurement,
and displayed on the graph with no offset.

running and a Trace is loaded. Only the calculated differential is
displayed on the graph.
Cable Setup button opens a new page that allows you to set the Cable
Parameters for the Current Test.
Select Graph button changes to Graph Selected when pressed and
opens a new selection of function keys which allow you to maneuver
the graph as follows:
Cursor/Marker allows you to select the cursor (blue) or marker
(red) independently by toggling the function key. The footer
updates to reflect either Move cursor or Move marker. Press the
left/right arrow keys to decrease/increase the values by moving the
cursor/marker. Press and hold the left/right arrow keys to
accelerate the cursor/marker. Press to recall the cursor/marker
and place it in the middle of the current x-axis limits.
Zoom references the middle of the x/y axis and not the cursor
position. Press the arrow keys as follows:
Right = x-axis zoom in.
Left = x-axis zoom out.
Up = y-axis zoom in.
Down = y-axis zoom out.
Pan - use left/right arrow keys to pan the x-axis and the up/down
arrow keys to pan the y-axis.
1:1 resets the x-axis and y-axis limits to full scale.
Return To Test removes these function keys and displays the
previous ones.
