    Writes the waveform to onboard memory as waveform data type data.

    waveform name

    The name of the waveform to configure position.

    You should name waveforms using this node under either of the following conditions:

    • You are using scripts.
    • You want to download multiple waveforms into the hardware.
    datatype_icon

    session in

    Instrument session obtained from the Initialize Acquisition Session node, the Initialize Generation Session node, or the Initialize External Calibration node.

    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

    datatype_icon

    data

    Parameter that provides a waveform to generate.

    This input accepts the following data types:

    • Waveform
    • 1D array of 8-bit unsigned integers
    • 1D array of 16-bit unsigned integers
    • 1D array of 32-bit unsigned integers
    datatype_icon

    use rate from waveform

    A Boolean that specifies how the sample rate is computed.

    True The sample rate from the WDT value is computed.
    False The sample rate from the WDT value is not computed.

    If the sample rate has been configured using the Configure Sample Clock node, use rate from waveform overrides the sample rate.

    Default: False

    datatype_icon

    session out

    Handle that identifies the session in all subsequent node calls.

    The session out parameter is obtained from the Initialize Acquisition Session node or the Initialize Generation Session node.

    datatype_icon

    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
