Hardware Setup (Dac Output); Getting Started – Single Tone Test - Analog Devices AD9783 Quick Start Manual

Quick Start Guide

HARDWARE SETUP (DAC OUTPUT)

Once the DPGDownloader software is installed, the hardware can be connected as shown in Figure 1. A single 5V power supply
powers the evaluation board. The power supply should be able to source up to 600mA to cover all of the board's operating
conditions. A low jitter clock source (< 0.5psec RMS) should be used for the DAC sampling clock CLKP/N. A sinusoidal clock
output level of 0 to 4dBm is optimal. By default, the DAC outputs are connected to SMA's J5,7,8,9. The modifications required
for observing the Modulator output will be explained. The evaluation board plugs directly into the DPG2. The PC connects to
both the DPG2 and the evaluation board through USB cables.

It is suggested that the basic set-up is verified before making any modifications to the evaluation board.
Basic Hardware Set-Up
Connect the equipment to the AD9783 evaluation board per the following table:

DPGDownloader Software
Power up the DPG and connect the USB cable to the PC. Next, run the DPGDownloader Software. A shortcut will be installed to
your Start menu during the installation of the DAC Software Suite. To begin, click on the DPGDownloader shortcut in your
Programs menu, typically at Start > Programs > Analog Devices > DPG > DPGDownloader.
The basic parts of the DPGDownloader window are: Hardware Config Panel, SPI GUI Launch Button, Vector Generation Pull-
Down Menu, Vector Palette, Vector Selection Panel and the Download and Play buttons.
