IviScope Configure AC Line Trigger Slope
IviScopeAcLineTrigger Capability Group [AT]
This VI configures the slope of the AC Line trigger.
 |
Note This VI affects instrument behavior only if the trigger type is IVISCOPE_VAL_AC_LINE_TRIGGER. Call the IviScope Configure Trigger VI to set the trigger type before calling this VI. |
 |
instrument handle The instrument handle that you obtain from the IviScope Initialize or the IviScope Initialize With Options VI. |
 |
trigger slope Specify whether you want the oscilloscope to trigger 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 AC Line Trigger Slope [AT] property.
Defined Values: IVISCOPE_VAL_AC_LINE_POSITIVE—Positive crossing IVISCOPE_VAL_AC_LINE_NEGATIVE—Negative crossing IVISCOPE_VAL_AC_LINE_EITHER—Either crossing Default value: IVISCOPE_VAL_AC_LINE_POSITIVE |
 |
error in (no error) The error in cluster can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
 |
instrument handle out The instrument handle that you obtain from the IviScope Initialize or the IviScope Initialize With Options VI. |
 |
error out The error out cluster passes error or warning information out of a VI to be used by other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
