C Function Prototype
ViStatus IviScope_ConfigureAcLineTriggerSlope (ViSession vi, ViInt32 acLineSlope);
Purpose
This function configures the slope of the AC Line trigger.
This function affects instrument behavior only if the trigger type is IVISCOPE_VAL_AC_LINE_TRIGGER. Call the IviScope_ConfigureTrigger function to set the trigger type before calling this function.
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. |
| acLineSlope | ViInt32 | Specifies whether an oscilloscope triggers on a zero crossing with a positive, negative, or either slope of the network supply voltage. The driver uses this value to set the IVISCOPE_ATTR_AC_LINE_TRIGGER_SLOPE attribute. |
