AD9910/PCBZ
The Edit Phase Offset dialog box (see Figure 8) appears by
double-clicking the Phase Offset text box in the Profiles
window. The Edit Phase Offset window allows you to set
individual bits in the phase offset word register. These bits
can be typed in as decimal, hexadecimal, or binary in the
Register Values area. This window also allows you to type in
a tuning word and see the correct decimal, hexadecimal, or
binary representations for this word. The Phase Offset spin box
allows you to scroll through the different tuning words one bit
at a time using the up and down arrows.
The Edit Output Scale Factor dialog box (see Figure 9) appears
by double-clicking the Amplifier SF text box in the Profiles
window. The Edit Output Scale Factor window allows you to
set individual bits in the ASF scale factor register. These can be
typed in as decimal, hexadecimal, or binary. This window also
allows you to type in a tuning word and see the correct decimal,
hexadecimal, or binary representations for this word. The Output
Scale Factor spin box allows you to scroll through the different
tuning words one bit at a time using the up and down arrows.

Activate
In the Activate area of the Profiles window, you can select
which profile register to activate. The active profile register is
the one that supplies the frequency tuning and phase offset
words, along with the amplitude control and the DDS core. This
window controls three external pins, which can also be driven
by an external source.
Other Controls
Enable Profile ASF allows you to set the amplitude scale factor
in the Profile window. This allows the device to ramp to a value
less than full scale.
Enable Sine Out activates the sine output of the DDS; otherwise,
the cosine output is active.
Enable RAM allows you to enable the RAM playback from this
window. (See the RAM Operation section for more information
on using the RAM.)
The RS OVR message box alerts you when a RAM sweep is
complete.
