Element' actions aligned with epochs of the parent event ¶

Epoch	Actions
After Onset	The element starts analyzing the selected signal
Control Loop step	The new signal data is analyzed withing the selected analysis window. The generated signal plots are updated.
Before Offset	The element stops analyzing the selected signal

Generic Properties ¶

Name	Description	Constraints	Value Type	Upon Runtime Change
Signal Source
Selected Signal	Defines the signal for processing by the element. The signals are provided by the data acquisition elements.	Design Time..	String
Sampling Rate	Defines the sampling rate of the original signal, in Hz	Design Time..	Int32
Analysis Window Size	Defines the size (in samples) of the moving analysis window for signal processing.	Design Time..	Int32
Signal Normalization	Defines the normalization procedure that is automatically applied to the signal before the analysis	Normal..	enumeration	The selected procedure is applied on the next analysis cycle
Bandpass Filter
Is Filtering	Defines whether the Butterworth bandpass filter is applied in signal plotting. This filter does not affect the signal analysis.	Normal..	Boolean
Filter Order	Defines the order of the Butterworth bandpass filter	Normal..	Int32
Low CutOff	Defines the low cutoff of the Butterworth bandpass filter, in Hz	Normal..	Double
High CutOff	Defines the high cut-off of the Butterworth bandpass filter, in Hz	Normal..	Double
Runtime Status
Is Running	Defines whether the analysis and plotting is going on in the present. You can use this property to temporally cease the signal processing for a sake of performance.	Normal..	Boolean
XAML Signal Plot	Returns a live XAML signal plot with the signal data. The plot can be used for direct binding to the Content property of the XAML ContentControl element, e.g. The ContentControl with a generated plot can be shown on the status screen or by the XAML Layout element.	Status..	XAML UIElement
Plotting
Plot Title	Defines the title of the generated signal plot	Normal..	String	The signal plot is updated with the new title
Plot Theme	Defines a visual theme of the generated signal plot	Normal..	enum	The signal plot is updated with the new theme
Line Thickness	Defines the thickness of the data line on the generated signal plot	Normal..	Double	The signal plot is updated with the new line thickness
Line Color	Defines the color of the data line on the generated signal plot	Normal..	stColor	The signal plot is updated with the new color
Max Y-Axis	Defines the range of the Y-axis (power) on the generated signal plot. Zero value denotes the auto-range.	Normal..	Double	The signal plot is updated with the new axis limit
Rendering Size	Defines the size of the generated plot in pixels. The plot is automatically stretched on rendering, but a larger rendering size improves the chart quality with some cost in performance. The rendering size is also used as the resulting image resolution, when the plot is exported into a file.	Design Time..	clSize
Signal Statistics
Mean	Returns the means of the signal values within the analysis window	Status..	double
Minimum	Returns the minimum of the signal values within the analysis window	Status..	double
Maximum	Returns the maximum of the signal values within the analysis window	Status..	double
Standard Deviation	Returns the standard deviations of the signal values within the analysis window	Status..	double
