RUNNING THE SOFTWARE
To run the evaluation board program, do the following:
1. Click Start/All Programs/Analog Devices/AD9833/
AD9833 Eval Board.
2. If the SDP board is not connected to the USB port when
the software is launched, a connectivity error displays (see
Figure 3). Simply connect the evaluation board to the USB
port of the PC, wait a few seconds, click Rescan, and follow
the instructions.
3. Ensure that all links are in their correct locations (see Table 1).
The main window of the AD9833DBZ evaluation software
then opens, as shown in Figure 4.
