IviPwrMeter Query Result Range Type (G Dataflow)

Version:
    Last Modified: October 24, 2017

    Takes a measurement value that is returned from one of the Fetch, Fetch Channel, Read, or Read Channel nodes and determines if the value is a valid measurement value or a value indicating that an out-of-range condition occurred.

    instrument handle

    Instrument handle that you obtain from IviPwrMeter Initialize or IviPwrMeter Initialize With Options. The handle identifies a particular instrument session.

    Default: None

    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

    measurement value (0.0)

    Pass the measurement value that you obtain from one of the Fetch or Read VIs. The driver tests this value to determine if the value is a valid measurement value or a value indicating an out-of-range condition occurred. Default Value: 0.0

    instrument handle out

    Instrument handle that you obtain from IviPwrMeter Initialize or IviPwrMeter Initialize With Options. The handle identifies a particular instrument session.

    Default: None

    error out

    Error information.

    The node produces this output according to standard error behavior.

    range type

    Returns whether the measurement value is a valid measurement or a value indicating that the power meter encountered an out-of-range condition. This driver defines the following range type: IVIPWRMETER_VAL_IN_RANGE (0) - The measurement is within the current range limits. IVIPWRMETER_VAL_UNDER_RANGE (-1) - The measurement is below the current lower range limits. IVIPWRMETER_VAL_OVER_RANGE (1) - The measurement is above the current upper range limits.

    Where This Node Can Run:

    Desktop OS: Windows

    FPGA: Not supported

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