SOFTWARE OPERATION 

The main window of the AD9523 evaluation board software 
comprises subsections that correspond to the major functional 
blocks of the AD9523 (see Figure 6). 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.  

When a subsection window closes after clicking 

OK

, the 

WRITE

 button on the main window may start blinking. This 

indicates that there are settings that have not been loaded to the 
AD9523 evaluation board. Click 

WRITE

 to load these settings 

to the evaluation board.
