Use the paste marker list for convenient entry of the reference value.

Ref. Position
Defines the position of the reference line in a Cartesian diagram.
The reference line is indicated by a symbol at the right edge of the diagram area. The color of the
symbol corresponds to the trace color. Ref. Position is defined on a linear scale between 0 (bottom line
of the diagram) and 10 (top line of the diagram). As the Ref. Position is varied, the value of the
reference line (Ref. Value) is left unchanged, so the current trace is shifted together with the Ref.
Position .
Ref. Position is not available (grayed) for polar diagrams (Polar, Smith, Inverted Smith) .
Use the analyzer's drag-and-drop functionality to move the reference line symbol to the desired
position.
Remote control: DISPlay:WINDow<Wnd>:TRACe<WndTr>:Y:RPOSition
Ref. Val = Marker
Sets the reference value equal to the response value of the active marker, leaving the values of the
vertical divisions (Scale Div.) unchanged.
•
In Cartesian diagrams the operation shifts the trace in vertical direction.
•
In polar diagrams (Polar, Smith, Inverted Smith), the operation re-defines the value of the outer
circumference and therefore enlarges or scales down the diagram, leaving the center
unchanged.
Use the analyzer's drag-and-drop functionality to move the reference line symbol to the desired
position.
Trace Select
The Trace Select submenu provides functions to handle traces and diagram areas, and assign traces to
channels.
