RUNNING THE SOFTWARE

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
