Using A and B Cursors
The Oscilloscope provides two "cursors": A and B. These can be used as a convenience by the user to mark
particular times along the X-axis. They can be shown or hidden by clicking on the Cursor A and Cursor B
toolbar buttons or by using the View → Cursor A and → Cursor B menu commands.
The cursors will appear as vertical lines through the
chart and each will have a small triangular "handle"
at the top end. This is shown in the figure below.
The cursors can be moved left or right by clicking on
the triangular handle with the right mouse button
and dragging the cursor left or right.
When the cursors are used, the value of each curve
at the position of the cursor is shown in the "Curve
Selection List". The column headings will contain the
X coordinate (time) of the position of each cursor.
As well, there will be a column containing the
difference between the curve values at the cursor
positions (i.e. the value at cursor "B" minus the
value at cursor "A"). This is shown in this figure:
Navigation Window
The Navigation Window displays an overview of the
entire chart. If the main Chart Window has been
zoomed, then this window allows the user to see
and move the position of the zoomed area relative
to the entire chart.
The zoomed area of the main chart will appear as a
black outline rectangle in the Navigation Window.
This is shown in the figure below. If Cursor A and
Cursor B are shown, then they will also be visible in
the Navigation Window.
