EVM View Setting
The horizontal axis indicates time, and the vertical axis indicates EVM,
amplitude, or phase in the EVM view. You can display this view in EVM
analysis of the digital modulation analysis (refer to page 3--51).
The Scale menu for the EVM view contains the following controls
(see Figure 3--140):
Auto Scale.
Sets the starting value and the scale of the vertical axis automatical-
ly to size the waveform to the screen.
Horizontal Scale.
Sets the range of the horizontal axis.
Horizontal Start.
Sets the minimum value (left edge) of the horizontal axis.
Vertical Scale.
Sets the range of the vertical axis.
Vertical Start.
Available when the vertical axis represents EVM.
Sets the minimum value (bottom) of the vertical axis.
Vertical Offset.
Available when the vertical axis represents magnitude or phase
error. Sets the center value ((m minimum) / 2) of the vertical axis.
Full Scale.
Sets the scale of the vertical axis to the default full-scale value.
