w = eyeWidth(obj)
measures the eye width of the eye diagram or eye contour object
obj.
w = eyeWidth(obj,amp)
measures the eye width of the eye diagram or eye contour object obj at
the amplitude specified by amp.
[w,amp] = eyeWidth(___,Name=Value)
measures the eye width and the returns the amplitude at which the eye height is measured
using one or more name-value pair arguments in addition to the input argument in the
previous syntax. Unspecified arguments take default values.
Eye diagram or eye contour object, specified as an eyeDiagramSI
System object™ or an eyeContour object.
Amplitude at which the function calculates the eye width, specified as a row vector.
If you do not provide the amp argument, the function returns the
best (largest) eye width across the eye opening.
Specify optional pairs of arguments as
Name1=Value1,...,NameN=ValueN, where Name is
the argument name and Value is the corresponding value.
Name-value arguments must appear after other arguments, but the order of the
pairs does not matter.
Example: w = eyeWidth(obj,Plot=on) displays the plot of the eye
diagram from the obj eye contour object showing the eye
width.
Symbol error rate for generating contours to measure eye width, specified as a
scalar.
If the input object obj is an eye diagram object, you can
define the SER value using this argument. If the input object
obj is an eye contour object, the function uses the
SER value set in the eye contour object and ignores this
argument.
Data Types: double
Extrapolation method for generating contours for generating contours to measure
eye width. For more information, see Extrapolation.
If the input object obj is an eye diagram object, you can
define the Extrapolation method using this argument. If the input
object obj is an eye contour object, the function uses the
Extrapolation method set in the eye contour object and ignores
this argument.
Measured eye width in amplitude units for each eye in the diagram, returned as a
column vector. The elements of the vector correspond to the amp
output.
Amplitude at which eye widths are measured, returned as a row vector.
