SOFTWARE OPERATION 

The main window of the AD9551 evaluation board software is 
comprised of subsections that correspond to the major functional 
blocks of the AD9551 (see Figure 4). These subsections, most of 
which have their own window, are outlined in this section. From 
the main window, the window for each functional block can be 
accessed by clicking the appropriate box in the main window.  

When a subsection window closes after clicking 

OK

, you may 

notice that the 

LOAD

 button on the main window starts 

blinking. This indicates that there are settings that have not 
been loaded to the AD9551 evaluation board. Click 

LOAD

 to 

load these settings to the evaluation board.
