Configure Runt Trigger Source [RT]

IVI Compliance Package

IviDigitizer Configure Runt Trigger Source [RT]

IviDigitizerRuntTrigger Capability Group

Configures the runt trigger. A runt occurs when the trigger signal crosses one of the runt thresholds twice without crossing the other runt threshold.

The end-user specifies the runt thresholds in the Threshold Low and Threshold High inputs. The end-user specifies the polarity of the runt in the Runt Polarity parameter.

Note Note  This VI affects instrument behavior only if the trigger type is runt trigger. Set the trigger type and trigger coupling before calling this VI.

IviDigitizer Configure Runt Trigger Source [RT].vi

cdbl Threshold Low (1.0) Sets the runt triggering low threshold in volts.

Unit: volt

Default Value: 1.0

civrn instrument handle The instrument handle that you obtain from the IviDigitizer Initialize VI or IviDigitizer Initialize With Options VI. The handle identifies a particular instrument session.

Default Value: None

cstr Trigger Source ("") Specifies the trigger source. This value sets the trigger source property.

Default Value: ""

Note Note  You can specify the trace name as a string variable or as a literal enclosed in double quotes.
ci32 Runt Polarity (Positive) Sets the runt polarity. This value sets the IviDigitizer Runt Trigger Polarity property.

Valid Values:

- IVIDIGITIZER_VAL_RUNT_POSITIVE (1)

The digitizer triggers on a positive runt. A positive runt occurs when a rising edge crosses the low runt threshold and does not cross the high runt threshold before re-crossing the low runt threshold.

- IVIDIGITIZER_VAL_RUNT_NEGATIVE (2)

The digitizer triggers on a negative runt. A negative runt occurs when a falling edge crosses the high runt threshold and does not cross the low runt threshold before re-crossing the high runt threshold.

- IVIDIGITIZER_VAL_RUNT_EITHER (3)

The digitizer triggers on either a positive or negative runt.

Default Value: IVIDIGITIZER_VAL_RUNT_POSITIVE (1)

cerrcodeclst 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.

cdbl Threshold High (1.0) Sets the runt triggering high threshold in volts.

Unit: volt

Default Value: 1.0

iivrn instrument handle out The instrument handle that you obtain from the IviDigitizer Initialize VI or IviDigitizer Initialize With Options VI. The handle identifies a particular instrument session.

Default Value: None

ierrcodeclst 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.
