eyeLinearity

Measure eye linearity

Since R2024a

Syntax

lin = eyeLinearity(obj)

lin = eyeLinearity(obj,time)

lin = eyeLinearity(___,Name=Value)

Description

lin = eyeLinearity(obj) measures the eye linearity from the eye diagram object obj.

lin = eyeLinearity(obj,time) measures the eye linearity from the eye diagram object obj at the time specified by time.

lin = eyeLinearity(___,Name=Value) measures the eye linearity from the eye diagram using one or more name-value pair arguments in addition to the input argument in the previous syntax. Unspecified arguments take default values.

Input Arguments

obj — Eye diagram object

eyeDiagramSI object

Eye diagram object, specified as an eyeDiagramSI System object™.

time — Time when eye linearity is calculated

scalar

Time at which the function calculates the eye linearity, specified as a scalar.

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: lin = eyeLinearity(obj,Extrapolation=Dual-Dirac) uses Dual-Dirac extrapolation method to generate the eye contours for measuring eye linearity.

SER — Symbol error rate

0 (default) | scalar

Symbol error rate at which the function measures eye linearity.

Data Types: double

Extrapolation — Extrapolation method to generate eye contours

None (default) | Dual-Dirac

Extrapolation method to generate eye contours used for measuring eye linearity.

Data Types: char

TimeUnit — Unit for time coordinates for measuring eye linearity

Seconds (default) | Samples | UI

Unit for the time coordinates for measuring eye linearity.

Data Types: char

Output Arguments

lin — Measured eye linearity

vector

Measured eye linearity.

Eye linearity is defined as the ratio of smallest eye amplitude to the largest eye amplitude in the eye diagram.
