EVALUATION BOARD SOFTWARE 

Use the following instructions to set up the AD9522 evaluation 
board software.  

SOFTWARE INSTALLATION 

Do not connect the evaluation board until the software 
installation is complete. 
1.

 

Insert the AD9522 evaluation software CD-ROM. The 
evaluation software and documentation can also be 
downloaded from2.

 

If using the CD, double-click 

My Computer

, and then 

double-click the 

AD9522EV CD

 icon. A window opens 

showing the contents of the CD divided into four sections: 

Datasheet

Layout

Schematic

, and 

Software

. Double-

click the 

Software

 folder. Checupdates to the evaluation software.  

3.

 

Double-click 

AD9522Eval_Setup1.1.0.exe

. Follow the 

installation instructions. The default location for the 
evaluation software is 

C:\Program Files\Analog Devices\ 

AD9522 Eval Software\

RUNNING THE SOFTWARE 

Power up and connect the evaluation board to the PC. See the 
Evaluation Board Hardware section for details on the various 
connectors on the evaluation board. 
1.

 

Double-click 

AD9522 Eval Software

 to run the AD9522 

evaluation software. Depending on whether the evaluation 
board was found by the software, either light blue text 
appears in a pop-up window, indicating that the evaluation 
board was found, or red text appears, indicating that the 
evaluation board was not found.  

2.

 

If the evaluation board is found, click anywhere in the pop-
up window with the 

Evaluation Software Ready

 message, 

and the main window for the software appears. Proceed to 
the Evaluation Software Components section for details 
about running the software. 
If the evaluation board is not found, a dialog box appears 
allowing you to select which AD9522-x evaluation board is 
connected while the software runs in standalone mode. 
Standalone mode is useful for viewing and generating 
register setup files. 

See the Evaluation Board Hardware section for information on 
connecting the evaluation board.  
If the evaluation board is connected while the evaluation 
software is running, the following window appears to prompt 
you to load the evaluation board with the evaluation software 
settings or read the evaluation board settings into the software.
