Ref. Value
Sets the reference line of a Cartesian diagram or the outer circumference of a circular diagram.
 In Cartesian diagrams Ref. Value defines the value of the reference line, indicated by a
symbol at the right edge of the diagram area. The color of the symbol corresponds to the trace
color. As the Ref. Value is varied, the position of the reference line (Ref. Position) is left
unchanged, so that the current trace is shifted in vertical direction. The unit of the Ref. Value
depends on the display format: dB for display format dB Mag, degrees for Phase and Unwrapped
Phase, ns for Delay, U (units) for all other (dimensionless) formats.
 In circular diagrams (Polar, Smith, Inverted Smith), Ref. Value defines the value of the outer
circumference. Changing Ref. Value enlarges or scales down the diagram, leaving the center
unchanged. The unit is U (units) for all circular diagrams.
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.
