IviDigitizer Configure Edge Trigger Source
IviDigitizerBase Capability Group
Sets the edge triggering properties. An edge trigger occurs when the trigger signal that the end-user specifies in the Trigger Source input passes through the voltage threshold that the end-user specifies in the Trigger Level input and has the slope that the end-user specifies in the Trigger Slope input.
This VI affects instrument behavior only if the IviDigitizer Trigger Type property is set to edge trigger. Set the IviDigitizer Trigger Type property and the IviDigitizer Trigger Coupling property before calling this VI.
If the trigger source is one of the analog input channels, an application program should configure the vertical range, vertical coupling, and the maximum input frequency before calling this VI.

Trigger Slope (Positive) Specifies the trigger slope. This value sets the IviDigitizer Trigger Slope property.
Valid Values: - IVIDIGITIZER_VAL_TRIGGER_SLOPE_NEGATIVE (0) A negative (falling) edge passing through the trigger level triggers the digitizer. - IVIDIGITIZER_VAL_TRIGGER_SLOPE_POSITIVE (1) A positive (rising) edge passing through the trigger level triggers the digitizer. Default Value: IVIDIGITIZER_VAL_TRIGGER_SLOPE_POSITIVE (1) |
 |
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 |
 |
Trigger Source ("") Specifies the trigger source that is to be configured.
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 |
 |
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 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. |
