external reference input to be used by that channel. If you do not specify
an external reference, the channel will use the internal reference. You
cannot use an external analog output reference with the
VXI-MIO-64XE-10. Analog output configuration options are explained
in the Analog Output section in Chapter 3, Hardware Overview. The
following ranges and ratings apply to the EXTREF input signal:
• Usable input voltage range:
• Absolute maximum ratings:
AOGND is the ground reference signal for both analog output channels
and the external reference signal.
Figure 4-8 shows how to make analog output connections and the
external reference input connection to your VXI-MIO Series module.

The external reference signal can be either a DC or an AC signal. The
module multiplies this reference signal by the DAC code (divided by
the full-scale DAC code) to generate the output voltage.
