Version:
    Last Modified: December 19, 2018

    Returns an array to indicate which calibration steps contain valid calibration data.

    datatype_icon

    session in

    Instrument session obtained from Initialize With Options .

    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

    session out

    Reference to your instrument session passed to the next node.

    datatype_icon

    error out

    Error information.

    The node produces this output according to standard error behavior.

    self calibration valid

    Boolean value that indicates whether the calibration data is valid.

    True The calibration data is valid.
    False The calibration data is invalid.

    valid steps

    Valid steps.

    Name Description
    Preselector Alignment Indicates the Preselector Alignment calibration data is valid. This step generates coefficients to align the preselector across the frequency range for your device.
    Gain Reference Indicates the Gain Reference calibration data is valid. This step measures the changes in gain since the last external calibration was run.
    IF Flatness Indicates the IF Flatness calibration data is valid. This step measures the IF response of the entire system for each of the supported IF filters.
    Digitizer Self Cal Indicates the Digitizer Self Cal calibration data is valid. This step calls for digitizer self-calibration, if the digitizer is associated with the RF downconverter.
    LO Self Cal Indicates the LO Self Cal calibration data is valid. This step calls for LO self-calibration, if the LO source module is associated with the RF downconverter.

    Omitting Steps

    To omit steps with valid calibration data from self-calibration, you can pass the valid steps output to the steps to omit input of Self Calibration .
