If the View is scaled linearly, the vertical scale is expressed in the display units. If the
View is logarithmic, the vertical scale is always dB/division. In this case, the reference
values (Y Max, Mid and Min) are still shown in the display units.
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}
X / Div (Polar)
Set the X/Division scale of the active display when the View is Nyquist or Nichols plot.
This value is the horizontal scale of the graph. The knob adjusts the scale in a 1-2-5-10
sequence. Changing the scale does not change the X Center location.
The X axis is scaled linearly and the scale is expressed in the display units.
The two displays can have different scales. This entry field can be linked to both displays
using the [Link] key.
Command: XDIV (?) d {, x}
Y Center (Polar)
Set the Y Center of the active display when the View is Nyquist or Nichols plot. The Y
Center is the Y axis value at the center of the graph. The Y Center has the same units as
the display.
The two displays can have different Y Center values. This entry field can be linked to
both displays using the [Link] key.
Command: YCEN (?) d {, x}
Y / Div (Polar)
Set the Y/Division scale of the active display when the view is Nyquist or Nichols plot.
This value is the vertical scale of the graph. The knob adjusts the scale in a 1-2-5-10
sequence. Changing the scale does not change the Y Center location.
