IviScopeBase Capability Group
C Function Prototype
ViStatus IviScope_ConfigureAcquisitionRecord (ViSession vi, ViReal64 timePerRecord, ViInt32 minNumPts, ViReal64 acqStartTime);
Purpose
This function configures the most commonly configured attributes of the oscilloscope acquisition subsystem. These attributes are the time per record, minimum record length, and acquisition start time.
Parameters
| Name | Type | Description |
|---|---|---|
| vi | ViSession | The instrument handle that you obtain from the IviScope_init or IviScope_InitWithOptions functions. The handle identifies a particular IVI session. |
| timePer Record | ViReal64 | Specifies the time per record. The driver uses this value to set the IVISCOPE_ATTR_HORZ_TIME_PER_RECORD attribute. |
| minNumPts | ViInt32 | Specifies the minimum number of points you allow in the waveform recorded. The driver uses this value to set the IVISCOPE_ATTR_HORZ_MIN_NUM_PTS attribute. |
| acqStart Time | ViReal64 | Specifies the position of the first point in the waveform record relative to the trigger event. The driver uses this value to set the IVISCOPE_ATTR_ACQUISITION_START_TIME attribute. |
