EVALUATION BOARD SOFTWARE
The AD5932EB evaluation kit is shipped with a CD-ROM that
includes self-installing software. The PC is connected to the
evaluation board using the supplied cable. The evaluation
software should be installed before connecting the evaluation
board to the PC’s USB port. This ensures that the evaluation
board is correctly recognized when connected to the PC.
The software is compatible with Windows® 2000 and Windows XP.
INSTALLING THE SOFTWARE
To insta ll the sof tware:
1. Start the Windows operating system and insert the CD.
The installation software should launch automatically. If it
does not, use Windows Explorer to locate the file setup.exe
on the CD. Double-click this file to start the installation
procedure.
2. At the prompt, select a destination directory. By default,
this is C:\Program Files\Analog Devices\AD5932.
Once the directory is selected, the installation procedure
copies the files into the relevant directories on the hard
drive. The installation program creates a program group
called Analog Devices with subgroup AD5932 in the Start
menu of the taskbar.
3. Once the installation procedure is complete, power up the
AD5932 evaluation board as described in the
Hardware
Description
section and connect it to the USB port of the
PC using the cable supplied.
4. Double-click the AD5932 icon to start the program. The
evaluation board is then automatically detected.
USING THE SOFTWARE
To launch the software, click on Start > All Programs > Analog
Devices > AD5932 > AD5932 Evaluation Software. The
software for the AD5932 board is presented in wizard format.
Note that no download of data to the evaluation board takes
place until you click the Write to Part command button in the
last screen (see
Figure 6). This means that it is possible to use
the software to help calculate the required write sequence
without having the board attached to the computer.

Both internal and external options for frequency incrementing
are offered. More details on all of these options can be found in
the
AD5932 data sheet.
