In circular diagrams
(Polar, Smith, Inverted Smith)
, the analyzer re-calculates the values of the
radial divisions so that the diagram is confined to approx. 80% of the outer circumference. The
reference value is set to the value of the outer circumference.
Autoscale does not affect the stimulus values and the horizontal axis.
Remote control:
DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:Y[:SCALe]:AUTO ONCE
Autoscale All
Adjusts the
Scale Divisions
and the
Ref. Value
in order
to display all traces in the diagram area, leaving an
appropriate display margin. This scale settings are analogous to the
Autoscale
function. The traces in the
active diagram area are taken into account irrespective of their channel assignment.
Scale / Div
Sets the value of the vertical diagram divisions in Cartesian diagrams.
Scale /Div
corresponds to the increment between two consecutive grid lines. The unit 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.
Scale /Div
is not available (grayed) for circular diagrams
(Polar, Smith, Inverted Smith)
.
Remote control:
DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:Y:PDIVision
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.
Remote control:
DISPlay[:WINDow<Wnd>]:TRACe<WndTr>:Y:RLEVel
Ref Position
Defines the position of the reference line in a Cartesian diagram.
