The following comments give additional details on the program examples in
this chapter.
The AFG stores the DAC codes directly into memory. Thus, the amplitude
setting has no affect on the codes. Unlike sending a voltage list, the output
amplitude can be set to any of the values listed in Appendix B. The
amplitude does not have to be to the maximum DAC code value.
The AFG requires that the data it receives must be correct, or it will not
execute it correctly. Unlike using other data transfer methods, the AFG does
not perform any error checking on the data when it is directly downloaded.
