RUNNING AND USING THE SOFTWARE 

To launch the evaluation software: 

1.

 

Find the executable, 

AD9956v.exe

, in the following folder: 

c:\Program Files\ADI\AD9956 Evaluation Software 

2.

 

Double-click the icon to launch the evaluation software.  A 
status window similar to Figure 2 appears  in the center of 
the 

AD9956 Evaluation Software

 dialog box as progress is 

made in loading the evaluation software (a black window 
with green text). If the software loads successfully, the text 
remains green and the “software up and running” message 
is displayed. If the loading fails, the text turns red, and a 
message describing the failure is displayed.  

Three dialog boxes are automatically loaded: 

Control

Profile

and 

DUT Signals

. You can load other dialog boxes from the 

View

 menu. You can also program the registers of the device 

directly from the 

Debug Window

, which you can access from 

the 

View

 menu.  

At startup, the software searches for the presence of a function-
ing AD9956 evaluation board. If it detects the evaluation board, 
a green splash screen appears, as shown in Figure 2. If it fails to 
detect a working part, a red error message is displayed.
