. (Note 

that the website may have a version newer than Version 
1.1.0.) Follow the installation instructions. The default 
location for installation of the evaluation software is: 

C:\Program Files\Analog Devices\AD9516 Eval Software\

RUNNING THE SOFTWARE 

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

1.

 

Double-click 

AD9516_17_18 Eval Software

 to run the 

AD951x 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.

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 AD951x evaluation board is 
connected while the software runs in standalone mode. 

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 window in Figure 2 appears to prompt 

you to load the evaluation board with the evaluation software 
settings or read the evaluation board settings into the software.
