Create Scatter Plot scope
h = commscope.ScatterPlot
h = commscope.ScatterPlot('PropertyName',PropertyValue,...)
commscope.ScatterPlot collects data and displays
results in a Figure window. You can create a scatter plot using a
default configuration or by defining properties.
h = commscope.ScatterPlot returns a scatter
plot scope, h.
h = commscope.ScatterPlot('PropertyName',PropertyValue,...) returns
a scatter plot scope, h, with property values set
PropertyValues. See the Properties section of
this help page for valid PropertyNames.
A ScatterPlot object has the properties shown on the following table. All properties are writable except for the ones explicitly noted otherwise.
|Type||'Scatter Plot'. This is a read-only property.|
|SamplingFrequency||Sampling frequency of the input signal in Hz.|
|SamplesPerSymbol||Number of samples used to represent a symbol.|
|SymbolRate||The symbol rate of the input signal. This property is read-only
and is automatically computed based on |
|MeasurementDelay||The time in seconds the scope will wait before starting to collect data.|
|SamplingOffset||The number of samples skipped at each sampling point relative
to the |
|Constellation||Expected constellation of the input signal.|
|RefreshPlot||The switch that controls the plot refresh style. The choices
|SamplesProcessed||The number of samples processed by the scope. This value does
not include the discarded samples during the |
|PlotSettings||Plot settings control the scatter plot figure. |
A Scatter Plot has the following methods.
This method automatically scales the plot figure so its entire contents displays.
This method closes the scatter plot figure.
This method displays the scatter plot properties.
This method creates a scatter plot figure. If a figure exists, this method updates the figure's contents.
plot(h) plots a scatter plot figure using
This method resets the collected data of the scatter plot object.
reset(h) resets the collected data of the
scatter plot object
clears the plot and
This method updates the collected data of the scatter plot.
update(h, r) updates the collected data of
the scatter plot, where h is the handle of the
scatter plot object and r is the complex input
data under test. This method updates the collected data and the plot
RefreshPlot is true).
