IviFgen Abort Generation (G Dataflow)

Version:
    Last Modified: October 23, 2017

    Aborts a previously initiated signal generation. If the function generator is in the Output Generation State, this node moves the function generator to the Configuration State. If the function generator is already in the Configuration State, the node does nothing. You can configure the output of the function generator regardless of whether the function generator is in the Configuration State or the Generation State. This means that you are not required to call the IviFgen Abort Generation Node prior to configuring the output of the function generator. Many function generators constantly generate an output signal, and do not require you to abort signal generation prior to configuring the instrument. If a function generator's output cannot be aborted (i.e., the function generator cannot stop generating a signal) this function does nothing. You are not required to call the IviFgen Initiate Generation and IviFgen Abort Generation nodes. Whether you choose to call these nodes in an application program has no impact on interchangeability. You can choose to use these nodes if you want to optimize your application for instruments that exhibit increased performance when output configuration is performed while the instrument is not generating a signal. Notes: (1) This node does not normally 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 IviFgen Error-Query Node at the conclusion of the sequence.

    instrument handle

    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

    datatype_icon

    error in

    Error conditions that occur before this node runs.

    The node responds to this input 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.

    Default: No error

    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.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

    Web Server: Not supported in VIs that run in a web application
