IviDigitizer Configure Runt Arm Source [RA]
IviDigitizerRuntArm Capability Group
Configures the runt arm. A runt occurs when the arm signal crosses one of the runt thresholds twice without crossing the other runt threshold.
The end-user specifies the runt thresholds with in the Threshold Low and Threshold High inputs. The end-user specifies the polarity of the runt with the Runt Polarity input.
 |
Note This VI affects instrument behavior only if the arm type is runt trigger. Set the arm type and trigger coupling before calling this VI. |

 |
Threshold Low (1.0) Sets the runt triggering low threshold in volts.
Unit: volt Default Value: 1.0 |
 |
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 |
 |
Arm Source ("") Specifies the arm source. This value sets the arm source property.
Default Value: "" Note: You can specify the trace name as a string variable or as a literal enclosed in double quotes. |
 |
Runt Polarity (Positive) Sets the runt polarity. This value sets the IviDigitizer Runt Arm 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) |
 |
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. |
|
Threshold High (1.0) Sets the runt triggering high threshold in volts.
Unit: volt Default Value: 1.0 |
 |
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 |
 |
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. |
