GETTING STARTED
This quick-start will setup a single-tone output from the AD9739 to provide a brief introduction to the part, as well as a basic
functionality test. To begin, open the AD9739 SPI application (Start > Programs > Analog Devices > AD9739-R2-EBZ > AD9739 SPI).
Connect a +5Vdc power supply to J17, and connect a 2GHz, 0dBm clock to J3.
Enable Mu Controller
In order to optimize and lock the Mu Controller, it is only necessary to have the DAC clock running (no data needs to be presented).
Click the MU_ENA button in the MU Controller section of the SPI application, as shown in Figure 2. Then run the SPI application by
clicking on the Run button (
) in the upper left of the screen.

Open DPGDownloader (Start > Programs > Analog Devices > DPG > DPGDownloader). Ensure that “AD9739” is selected in the
Evaluation Board
drop-down list. For this evaluation board, “LVDS” is the only valid
Port Configuration
, and will be selected
automatically. The
Data Clock Frequency
display should read approximately 500MHz.

, and then
Single Tone
, as shown in Figure 3. A Single Tone panel will be added to the vector list. Start
by entering the Clock Frequency (2GHz in this case). You can enter 2G in the box. Next, enter 180MHz (180M) as the desired frequency
of the tone. The DAC Resolution should be set at 14 bits.
