Element actions aligned with different epochs of the parent event ¶

Epoche	Actions
Initialized	The camera starts capturing video
Rendered
Activating
Activated
Running	The camera output is captured and rendered via the Video Output property, if the latter is bound to the status screen
Deactivated
Deinitialized	The camera stops capturing video

+=== Properties inherited from the base signal provider element === Inherited properties of the Signal Provider Element

Channel Configuration
Selected Channels	Defines what signal channels are selected for acquisition within EventIDE. Selected channels are registered in the EventIDE signal pool at runtime and become available for the signal analysis elements.	Design Time..	IList
Selected Channel Count	Indicates how many signal channels are currently selected for acquisition.	Status..	Int32
Total Channel Count	Indicates how many signal channels are available for acquisition in the total.	Status..	Int32
Buffer Size	Defines the size (in samples) of a circular buffer that stores incoming signal data.	Design Time..	Int32
Signal Generator
Signal Source	Defines a source for the signal. The emulated rhythmes can be used for offline validation of the chosen analysis settings	Design Time..	enum
Emulated Sampling Rate	Defines the emulation sampling rate (samples per second), when data is generated or streamed from a file.	Design Time..	Int32
Primary Frequency	Defines the frequency of the primary rhythm in the generated signal, in Hz. Assign the zero to exclude the primary frequency from the generated signal.	Design Time..	Double
Secondary Frequency	Defines the frequency of the secondary rhythm in the generated signal, in Hz. The secondary frequency magnitude is a half of the primary frequency magnitude. Assign the zero to exclude the secondary frequency from the generated signal.	Design Time..	Double
Noise Level	Defines the noise level (in % to the norm magnitude of the primary frequency). The noise is added to the generated signal. Assign the zero the exclude the noise from the generated signal.	Design Time..	Double
External Datafile	Opens the dialog for selecting a data file containing a stream of double numbers representing a signal. If a file name without a path is defined, the data file will be picked up in the location of the experiment file.	Designtime Command..	String
