- If the AD9783 evaluation board has been recognized by the PC, AD9783 should be populated in the Evaluation Board
field in the Hardware Config panel.
- Generate a sine wave by pulling down the “Add Generated Waveform” menu and choosing “Single Tone”. Fill in the form
as shown in (Sample Rate = 300MHz, Desired Frequency = 50 MHz, etc.). Check the “Generate Complex Data (I&Q)”
box. Note that the Sample Rate should match the input sample rate or the DAC update rate since this part has no
interpolation. Also, the Unsigned data needs to be unchecked because the AD9783 SPI defaults to 2’s complement data
format.
- Select the I and Q data vectors in the data selection panel.
- Launch the AD9783 SPI GUI by clicking the AD9783 SPI button.

button is clicked, the SPI controller will run continuously. It will both write and read from the AD9783.
- The DCO frequency field in the DPGDownloader window should now be reading something close to 500MHz.
- Next hit the download button. This transfers the data from the PC to the DPG memory.
