Configure Sample Clock (G Dataflow)

Version:
    Last Modified: September 27, 2017

    Configures the Sample clock. This node allows you to specify the Sample clock source and rate.

    If clock source is set to On Board Clock, NI-HSDIO coerces the rate to a value that is supported by the hardware. Select Timing»Sample Clock»Rate from the Property node to get the coerced value of the Sample clock rate. Only set clock source to Strobe for acquisition sessions, or NI-HSDIO returns an error.

    connector_pane_image
    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

    clock source

    The sample clock source.

    You can select On Board Clock, ClkIn, PXI STAR Line, Strobe, or PXIe DStarA as the value for this control.

    datatype_icon

    clock rate

    The Sample clock rate, expressed in Hz.

    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

    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
