IviScope_InitiateAcquisition
IviScopeBase Capability Group
C Function Prototype
ViStatus IviScope_InitiateAcquisition (ViSession vi);
Purpose
This function initiates a waveform acquisition.
After calling this function, the oscilloscope leaves the Idle state and waits for a trigger. The oscilloscope acquires a waveform for each channel you enable with the IviScope_ConfigureChannel function.
This function does not check the instrument status. Typically, you call this function only in a sequence of calls to other low-level driver functions. The sequence performs one operation. Use the low-level functions to optimize one or more aspects of interaction with the instrument. Call the IviScope_error_query function at the conclusion of the sequence to check the instrument status.
