IviDigitizer Configure Edge Arm Source [ARM]
Sets the edge arming properties. An edge occurs when the arm signal that the end-user specifies in the Arm Source input passes through the voltage threshold that the end-user specifies with the Arm Level input and has the slope that the end-user specifies with the Trigger Slope input.
Notes:
(1) This VI affects instrument behavior only if the Arm Type is Edge Arm. Set the Arm Type and Arm Coupling before calling this VI.
(2) If the arm 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.
(3) This VI is part of the IviDigitizerArm [ARM] extension group.

 |
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. |
 |
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. |
 |
Arm Level (1.0) Specifies the arm level. This value sets the IviDigitizer Arm Level property.
Unit: volt Default Value: 1.0 |
 |
Trigger Slope (Positive) Specifies the trigger slope. This value sets the IviDigitizer Arm Slope property.
Valid Values: - IVIDIGITIZER_VAL_TRIGGER_SLOPE_NEGATIVE (0) A negative (falling) edge passing through the arm level triggers the digitizer. - IVIDIGITIZER_VAL_TRIGGER_SLOPE_POSITIVE (1) A positive (rising) edge passing through the arm level triggers the digitizer. Default Value: IVIDIGITIZER_VAL_TRIGGER_SLOPE_POSITIVE (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. |
