IviScope ContinuousAcquisition Behavior Model

The following behavior diagram shows relationships between IviScopeContinuousAcquisition capabilities and oscilloscope behavior.

IviScope ContinuousAcquisition Behavior Model

The IviScopeContinuousAcquisition extension group adds the attribute that controls whether the instrument operates in a single-shot mode or it acquires the data continuously.

After the oscilloscope completes an acquisition, if the IVISCOPE_ATTR_INITIATE_CONTINUOUS is set to VI_TRUE, the instrument goes to the Wait-for-Trigger state instead of returning to the Idle state. In the Wait-for-Trigger state, the oscilloscope display updates continuously. This specification does not define the behavior of the read and fetch functions when this attribute is set to VI_TRUE. The behavior of these functions is instrument specific.
