    Sends a command to trigger the spectrum analyzer.

    Call this node if you pass IVISPECAN_VAL_TRIGGER_SOURCE_SOFTWARE for the IviSpecAn>>Trigger>>Trigger Source property or the Trigger Source parameter of the IviSpecAn Configure Trigger Source [TRG] node.

    Note  

    If the IviSpecAn>>Trigger>>Trigger Source is not set to the IVISPECAN_VAL_TRIGGER_SOURCE_SOFTWARE value, this VI returns the Trigger Not Software error (0xBFFA1001).

    Note  

    This node does not check the instrument status. Typically, you call this node only in a sequence of calls to other low-level driver nodes. The sequence performs one operation. You use the low-level nodes to optimize one or more aspects of interaction with the instrument. If you want to check the instrument status, call the IviSpecAn Error-Query Node at the conclusion of the sequence.

    instrument handle out

    The instrument handle that you obtain from the IviSpecAn Initialize Node or IviSpecAn 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.
