... To prove that this device will meet the user’s waveform synthe- sis requirements, the user requires only a 3 power supply, an IBM-compatible PC and a spectrum analyzer along with the evaluation board. The evaluation board setup is shown below. The DDS evaluation kit includes a populated, tested AD9832 printed circuit board, along with the software that controls the AD9832 Windows environment ...
