    instrument handle

    The instrument handle that you obtain from the IviFgen Initialize or IviFgen 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

    Sample Clock Source

    Pass the sample clock source you want the function generator to use. The driver sets the IviFgen Sample Clock Source [SC] property to this value. The value you specify determines the clock used for the waveform generation. If you want to set this parameter to IVIFGEN_VAL_SAMPLE_CLOCK_SOURCE_EXTERNAL (1), you must first set the arbitrary sample rate to the corresponding frequency of the external sample clock. You can use the IviFgen Configure Sample Rate [ARB] Node or set the IviFgen Sample Rate [ARB] property to configure the arbitrary sample rate.

    Defined Values

    IVIFGEN_VAL_SAMPLE_CLOCK_SOURCE_INTERNAL (0) - Use the internal sample clock.

    IVIFGEN_VAL_SAMPLE_CLOCK_SOURCE_EXTERNAL (1) - Use an external sample clock

    Default: IVIFGEN_VAL_SAMPLE_CLOCK_SOURCE_INTERNAL (0) - Use the internal sample clock

    instrument handle out

    The instrument handle that you obtain from the IviFgen Initialize or IviFgen 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
