Returns an array to indicate which calibration steps contain valid calibration data. To omit steps with valid calibration data from self-calibration, you can pass the valid steps output to the steps to omit input on the niRFSA Self Cal VI.

Supported Devices: PXI-5661, PXIe-5663/5663E/5665/5667/5668

Inputs/Outputs

  • civrn.png instrument handle —

    instrument handle identifies your instrument session. instrument handle is obtained from the niRFSA Initialize VI or the niRFSA Initialize With Options VI.

  • cerrcodeclst.png error in —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • iivrn.png instrument handle out —

    instrument handle out passes a reference to your instrument session to the next VI. instrument handle is obtained from the niRFSA Initialize VI or the niRFSA Initialize With Options VI and identifies a particular instrument session.

  • ibool.png self cal valid —

    self cal valid returns TRUE if all the calibration data is valid and FALSE if any of the calibration data is invalid.

  • i1di64.png valid steps —

    valid steps returns an array of valid steps.

    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.
  • ierrcodeclst.png error out —

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