IviDigitizer Configure Width Trigger Source [WT]
IviDigitizerWidthTrigger Capability Group
Configures the width trigger source, and the IviDigitizer Trigger Level, IviDigitizer Width Trigger Low Threshold, IviDigitizer Width Trigger High Threshold, IviDigitizer Width Trigger Polarity, and IviDigitizer Width Trigger Condition properties.
 |
Note A width trigger occurs when a pulse, that passes through Level, with a width between or outside, the width thresholds is detected. |

Width Polarity (Positive) Sets the width polarity. This value sets the IviDigitizer Width Trigger Polarity property.
Valid Values: - IVIDIGITIZER_VAL_WIDTH_POSITIVE (1) Configures the digitizer to trigger on positive pulses that have a width that meets the condition the user specifies with the IviDigitizer Width Trigger Condition property. - IVIDIGITIZER_VAL_WIDTH_NEGATIVE (2) Configures the digitizer to trigger on negative pulses that have a width that meets the condition the user specifies with the IviDigitizer Width Trigger Condition property. - IVIDIGITIZER_VAL_WIDTH_EITHER (3) Configures the digitizer to trigger on either positive or negative pulses that have a width that meets the condition the user specifies with the IviDigitizer Width Trigger Condition property. Default Value: IVIDIGITIZER_VAL_WIDTH_POSITIVE (1) |
 |
Threshold Low (1.0) Sets the width triggering low threshold, in seconds. This value sets the IviDigitizer Width Trigger Low Threshold property.
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 |
 |
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. |
 |
Trigger Source ("") Specifies the trigger source. This value sets the trigger source property.
Default Value: "" Note: You can specify the trace name as a string variable or as a literal enclosed in double quotes. |
|
Trigger Level (1.0) Specifies the trigger level. This value sets the IviDigitizer Trigger Level property.
Unit: volt Default Value: 1.0 |
|
Threshold High (1.0) Sets the width triggering high threshold in seconds. This value sets the IviDigitizer Width Trigger High Threshold property.
Unit: volt Default Value: 1.0 |
|
Width Condition (Within) Specifies whether a pulse that is within or outside the user-specified thresholds trigger waveform acquisition. This value sets the IviDigitizer Width Trigger Condition property.
Valid Values: - IVIDIGITIZER_VAL_WIDTH_WITHIN (1) Configures the digitizer to trigger on pulses that have a width that is less than the high threshold and greater than the low threshold. The end-user specifies the high and low thresholds with the IviDigitizer Width Trigger High Threshold and IviDigitizer Width Trigger Low Threshold properties. - IVIDIGITIZER_VAL_WIDTH_OUTSIDE (2) Configures the digitizer to trigger on pulses that have a width that is either greater than the high threshold or less than a low threshold. The end-user specifies the high and low thresholds with the IviDigitizer Width Trigger High Threshold and IviDigitizer Width Trigger Low Threshold properties. Default Value: IVIDIGITIZER_VAL_WIDTH_WITHINS (1) |
 |
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. |
