EVALUATION BOARD SOFTWARE 

SOFTWARE OPERATION 

SOFTWARE INSTALLATION 

To launch the software, complete the following steps: 

The 

AD5791

 evaluation kit includes self-installing software on  

a CD. The software is compatible with Windows XP (SP2) and 
Vista (32-bit). If the setup file does not run automatically, you 
can run 

setup.exe

 from the CD.  

1.

 

From the 

Start

 menu, select 

Analog Devices – AD5791

 > 

AD5791 Evaluation Software

. The main window of the 

software is displayed (see Figure 3). 

Install the evaluation software before connecting the evaluation 
board and SDP board to the USB port of the PC to ensure that 
the evaluation system is correctly recognized when connected to 
the PC. 

2.

 

If the evaluation system is not connected to the USB port 
when the software is launched, a connectivity error is 
displayed (see Figure 2). Connect the evaluation board to 
the USB port of the PC, wait a number of seconds, and 
click 

Rescan. 

Follow the instructions. 

1.

 

After installation from the CD is complete, power up  
the AD5791 evaluation board as described in the Power 
Supplies section. Connect the SDP board to the AD5791 
evaluation board and then to the USB port of your PC 
using the supplied cable.
