IviDigitizer Configure Glitch Arm Source [GA] (G Dataflow)

Last Modified: October 24, 2017

Configures the glitch arm. A glitch arm occurs when the arm signal has a pulse with a width that is less than or greater than the glitch width.

The end user specifies which comparison criterion to use with the GlitchCondition parameter. The end-user specifies the glitch width with the Glitch Width input. The end-user specifies the polarity of the pulse with the Glitch Polarity input.

The arm does not actually occur until the edge of a pulse that corresponds to the Glitch Width input and Glitch Polarity input crosses the threshold the end-user specifies in the trigger level parameter. This node affects instrument behavior only if the arm type is glitch arm.

Glitch Polarity (Positive)

Specifies the glitch polarity. This value sets the IviDigitizer Glitch Arm Polarity property. Valid Values: - IVIDIGITIZER_VAL_GLITCH_POSITIVE (1) The digitizer triggers on a positive glitch. - IVIDIGITIZER_VAL_GLITCH_NEGATIVE (2) The digitizer triggers on a negative glitch. - IVIDIGITIZER_VAL_GLITCH_EITHER (3) The digitizer triggers on either a positive or negative glitch. Default Value: IVIDIGITIZER_VAL_GLITCH_POSITIVE (1)

Glitch Width (0.1)

Specifies the glitch arming glitch width, in seconds. This value sets the IviDigitizer Glitch Arm Width property. Unit: second Default Value: 0.1

datatype_icon

Glitch Condition (Less Than)

Specifies the glitch condition. This value sets the IviDigitizer Glitch Arm Condition property. Valid Values: - IVIDIGITIZER_VAL_GLITCH_LESS_THAN (1) The digitizer triggers when the pulse width is less than the value you specify with the IviDigitizer Glitch Arm Width property. - IVIDIGITIZER_VAL_GLITCH_GREATER_THAN (2) The digitizer triggers when the pulse width is greater than the value you specify with the IviDigitizer Glitch Arm Width property. Default Value: IVIDIGITIZER_VAL_GLITCH_LESS_THAN (1)

datatype_icon

Arm Level (1.0)

Specifies the arm level. This value sets the IviDigitizer Arm Level property. Unit: volt Default Value: 1.0

datatype_icon

Arm Source ("")

Specifies the arm source. This value sets the arm source property. Users who want to achieve interchangeability should use a virtual arm source name. The virtual arm source name should be sufficiently specific to the test system such that it is unlikely to conflict with a physical arm source name. Default Value: "" Note: You can specify the trace name as a string variable or as a literal enclosed in double quotes.

instrument handle out

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

Default: None

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.
