Self-calibrates the NI-RFSA device and associated modules that support self-calibration. If self-calibration completes successfully, the new calibration constants are stored immediately in the nonvolatile memory of the module. On a MIMO session, this VI self-calibrates all NI-RFSA devices and associated modules that support self-calibration.

Refer to the specifications document for your device for more information about how often to self-calibrate. For more information about Self Calibrate, refer to the niRFSA Self Cal VI topic for your device in the NI RF Vector Signal Analyzers Help.

Note For PXIe-5644/5645/5646, RFmx internally closes the RFSA session, performs self-calibration and opens a new session for the same device. If the RFSA session has been accessed from RFmx, using the RFmxInstr Get NIRFSA Session VI before calling the RFmxInstr Self Calibrate VI, the RFSA session will become invalid upon calling the RFmxInstr Self Calibrate.

Supported devices: PXIe-5663/5663E/5665/5668, PXIe-5644/5645/5646, PXIe-5820/5830/5831/5832/5840/5841/5842/5860

Inputs/Outputs

  • 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.

  • c1di32.png steps to omit

    Steps To Omit specifies which calibration steps to skip during the self-calibration process. The default value is an empty array, which indicates that all calibration steps are performed. The only valid value for PXIe-5820/5830/5831/5832/5840/5841/5842/5860 is an empty array.

    Preselector Alignment (1)

    Omits the Preselector Alignment step. If you omit this step and the niRFSA Is Self Cal Valid VI indicates the calibration data for this step is invalid, the preselector alignment specifications are not guaranteed. This step applies only to the PXIe-5605/5606.

    Gain Reference (2)

    Omits the Gain Reference step. If you omit this step and the niRFSA Is Self Cal Valid VI indicates the calibration data for this step is invalid, the absolute accuracy of the device is not guaranteed.

    IF Flatness (4)

    Omits the IF Flatness step. If you omit this step and the niRFSA Is Self Cal, valid VI indicates the calibration data for this step is invalid, the IF flatness specifications are not guaranteed.

    Digitizer Self Cal (8)

    Omits the Digitizer Self Cal step. If you omit this step and the niRFSA Is Self Cal Valid VI indicates the calibration data for this step is invalid, the absolute accuracy of the device is not guaranteed.

    LO Self Cal (10)

    Omits the LO Self Cal step. If you omit this step and the niRFSA Is Self Cal Valid VI indicates the calibration data for this step is invalid, the LO PLL may fail to lock.

    Amplitude Accuracy (20)

    Not used by this VI.

    Residual LO Power (40)

    Not used by this VI.

    Image Suppression (80)

    Not used by this VI.

    Synthesizer Alignment (100)

    Not used by this VI.

    DC Offset (200)

    Not used by this VI.

  • cerrcodeclst.png error in (no error)

    error in 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.

  • ierrcodeclst.png error out

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