ViStatus IviScope_ConfigureRefLevels (ViSession vi, ViReal64 low, ViReal64 mid, ViReal64 high);
Purpose
This function configures the reference levels for waveform measurements. Call this function before calling the IviScope_ReadWaveformMeasurement or IviScope_FetchWaveformMeasurement to take a rise time, fall time, width negative, width positive, duty cycle negative, duty cycle positive, preshoot, or overshoot measurement.
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. |
low | ViReal64 | Measurement low reference. The driver uses this value to set the IVISCOPE_ATTR_MEAS_LOW_REF attribute. |
mid | ViReal64 | Measurement mid reference. The driver uses this value to set the IVISCOPE_ATTR_MEAS_MID_REF attribute. |
high | ViReal64 | Measurement high reference. The driver uses this value to set the IVISCOPE_ATTR_MEAS_HIGH_REF attribute. |
