PROFILES WINDOW
The AD9858 has four user-defined profiles (segments of memory). Each profile can be programmed with a different frequency tuning
word and phase adjustment word. As shown in Figure 12, users can click the Edit button next to any value for a dialog window in which
frequency and phase information may be entered.
While the value is displayed on the screen, it is not yet loaded to the device. To load the information, the user must click the Load button.
This button flashes after one or both of the variables in a profile is changed, and continues to flash until the data is loaded. Entering and
loading data does not automatically cause the DDS to change to the most recently addressed profile. In order to change profiles, the user
must click the profile name, which turns from a dark green to a bright green to indicate that it has been selected as the current profile.
