Returns an array to indicate which calibration steps contain valid calibration data. To omit steps with the valid calibration data from self-calibration, you can pass the Valid Steps parameter to the Steps To Omit parameter of the RFmxInstr Self Calibrate VI. On a MIMO session, use the Selector String parameter to get the self-calibration validity for a specific MIMO port.

Supported devices: PXIe-5663/5663E/5665/5668

Inputs/Outputs

  • cstr.png Selector String —

    Selector String specifies a Selector String comprising of a MIMO port on a MIMO session. The default value is "" (empty string).

    Example:

    ""

    "port::myrfsa1/0"

    You can use the RFmxInstr Build Port String VI to build the selector string.

  • cgenclassrntag.png Instrument Handle In —

    Instrument Handle In identifies the instrument session. Instrument Handle In is obtained from the RFmxInstr Initialize NIRFSA VI or the RFmxInstr Initialize NIRFSA (Array) VI.

  • cerrcodeclst.png error in (no error) —

    error in (no error) describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • igenclassrntag.png Instrument Handle Out —

    Instrument Handle Out passes a reference of the instrument session to the next VI.

  • ibool.png Self Calibrate Valid —

    Self Calibrate Valid returns TRUE if all the calibration data is valid and FALSE if any of the calibration data is invalid.

  • i1di32.png Valid Steps —

    Valid Steps returns an array of valid steps.

    Preselector Alignment (1)

    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 (2)

    Indicates the Gain Reference calibration data is valid. This step measures the changes in gain since the last external calibration was run.
    IF Flatness (4)

    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 (8)

    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 (10)

    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.
  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
