Many E Series boards have analog output functionality. E Series boards
that support analog output have two AO channels that are controlled by a
single clock and are capable of waveform generation. Refer to Appendix A,
Device-Specific Information, for specific information about the capabilities
of your device.
Digital-to-analog converters (DACs) convert digital codes to analog
voltages.
The DAC FIFO enables analog output waveform generation. It is a
first-in-first-out (FIFO) memory buffer between the computer and the
DACs that allows you to download all the points of a waveform to your
board without host computer interaction.
