Command: YMID (?) d {, x}
Y Min
Set the Y Minimum (bottom reference) of the active display. The bottom reference is the
Y value of the bottom of the graph. The bottom reference has the same units as the
display.
The two displays can have different bottom reference values. This entry field can be
linked to both displays using the [Link] key.
When Y Min is changed, the value of Y-Max is kept fixed and Y-mid and Y/Div are
adjusted.
Command: YMIN (?) d {, x}
Y / Div
Set the Y/Division scale of the active display. This value is the vertical scale of the
graph.
The knob adjusts the vertical scale in a 1-2-5-10 sequence. Knob adjustments set the Y
Midpoint (center reference) to the current Marker X Position. The Y Maximum and Y
Minimum are adjusted to give the effect of vertical zooming. Entering a scale
numerically leaves the Y Min (bottom reference) unchanged. The Y Max and Y Mid are
adjusted.
If the View is 'Log Mag' and <dB Units> are set 'Off,' then the graph will be
logarithmically scaled. In this case the box will display the total number of decades along
the Y-axis.
The two displays can have different vertical scales. This entry field can be linked to both
displays using the [Link] key.
Command: YDIV (?) d {, x}
X Center (Polar)
Set the X Center of the active display when the View is Nyquist or Nichols plot. The X
Center is the X axis value at the center of the graph. The X Center has the same units as
the display.
The two displays can have different X Center values. This entry field can be linked to
both displays using the [Link] key.
Command: XCEN (?) d {, x}
