IviDigitizer Configure Multi Trigger [MT] (G Dataflow)

Version:
    Last Modified: October 24, 2017

    Configures the digitizer to trigger based on multiple trigger sources.

    The digitizer can be instructed to trigger when any one of multiple trigger source conditions are met or when all specified trigger source conditions are met.

    Trigger Source Operator (And)

    Specifies the boolean operation to apply to the trigger sources specified by the Source List input. The driver uses this value to set the IviDigitizer Trigger Source Operator property. Valid Values: - IVIDIGITIZER_VAL_TRIGGER_SOURCE_OPERATOR_AND (0) Trigger sources are AND'd together. The digitizer triggers when all configured trigger source conditions are satisfied. - IVIDIGITIZER_VAL_TRIGGER_SOURCE_OPERATOR_OR (1) Trigger sources are OR'd together. The digitizer triggers when the first configured trigger source condition is satisfied. - IVIDIGITIZER_VAL_TRIGGER_SOURCE_OPERATOR_NONE (2) No operator is applied to the configured list of trigger sources. The trigger source list is ignored, and the digitizer triggers when the active trigger source, given by the IviDigitizer Active Trigger Source property, and its associated trigger conditions are satisfied. Default Value: IVIDIGITIZER_VAL_TRIGGER_SOURCE_OPERATOR_AND (0)

    Source List ("")

    Specifies the list of source names to be used in a multi-trigger scenario. You can specify multiple sources by separating the names with a comma. The driver uses this value to set the IviDigitizer Trigger Source List property. Users who want to achieve interchangeability should use a virtual trigger source name. The virtual trigger source name should be sufficiently specific to the test system such that it is unlikely to conflict with a physical trigger 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

    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.
