h = eyeHeight(obj)
measures the eye height of the eye diagram or eye contour object
obj.
h = eyeHeight(obj,time)
measures the eye height of the eye diagram or eye contour object obj at
the time specified by time.
[h,t] = eyeHeight(___,Name=Value)
measures the eye height and the returns the time 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.
time — Time when eye height is calculated row vector
Time at which the function calculates the eye height, relative to the sampling clock
edge, specified as a row vector.
Data Types: double
Name-Value Arguments
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: h = eyeHeight(obj,Plot=on) displays the plot of the eye
diagram from the obj eye diagram object showing the eye
height.
SER — Symbol error rate 0 | scalar
Symbol error rate for generating contours to measure eye height, 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.
Extrapolation method for generating contours for generating contours to measure
eye height.
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.
Data Types: char
TimeUnit — Unit for time coordinates Seconds (default) | Samples | UI
Unit for the time coordinates for the location of the eye height.
Data Types: char
Plot — Display eye height on plot off (default) | on
Display a plot of the eye diagram showing the eye height.
Measured eye height in amplitude units for each eye in the diagram, returned as a
matrix. The columns of the matrix correspond to the time values and rows correspond to
the eye openings. The function indexes the eye openings from the lowest center amplitude
to the highest.
t — Times at which eye heights are measured row vector
Times at which eye heights are measured, returned as a row vector.
