Appendix A: Calibration Utilities

NI-RFSG provides a full complement of external calibration VIs. You can use these VIs to 
retrieve information about adjustments performed on the PXI-5650/5651/5652. The External 
Calibration palette includes the following VIs:

niRFSG Initialize External Calibration VI

niRFSG Get External Calibration Last Date And Time VI

niRFSG Change External Calibration Password

niRFSG Update External Calibration Date and Time VI 

niRFSG Close External Calibration VI

Calibration VI References

The VIs used in this procedure, including all calibration VIs, are documented in the 

NI-RFSG VI 

Reference, 

which you can access from the 

NI RF Signal Generators Help
