The results of an internal calibration are stored in the NI PXI-4224 flash
memory so that the CalDACs are automatically loaded with the newly
calculated calibration constants the next time the NI PXI-4224 is
powered on.
Performing a self-calibration at the operating temperature of your
application will ensure the NI PXI-4224 meets the specifications in
Appendix A, Specifications.
