Other Considerations
The CalDACs adjust the gain error of each analog output channel by
adjusting the value of the reference voltage supplied to that channel. This
calibration mechanism is designed to work only with the internal 10 V
reference. Thus, in general, it is not possible to calibrate the analog output
gain error when using an external reference. In this case, it is advisable to
account for the nominal gain error of the analog output channel either in
software or with external hardware. See Appendix A,
, for
analog output gain error information.
