The IBDA_SignalStatistics interface is implemented on a BDA device filter and provides methods by which the filter can describe the condition of a signal that is being received.
In addition to the methods inherited from IUnknown, the IBDA_SignalStatistics interface exposes the following methods.
|get_SampleTime||Retrieves the sample time used to measure the signal.|
|get_SignalLocked||Retrieves a Boolean value indicating whether the signal is locked.|
|get_SignalPresent||Retrieves a Boolean value indicating whether a signal is present.|
|get_SignalQuality||Retrieves a value from 1 to 100 indicating the quality of the signal.|
|get_SignalStrength||Retrieves a value that indicates the strength of the signal in decibels.|
|put_SampleTime||Specifies the sample time used to measure the signal.|
|put_SignalLocked||Specifies whether the signal is locked.|
|put_SignalPresent||Specifies whether a signal is present.|
|put_SignalQuality||Specifies the quality of the signal.|
|put_SignalStrength||Specifies the strength of the signal in decibels.|
