Data Pattern Generator (DPG) High-Speed DAC Evaluation Platform

The Data Pattern Generator is a bench-top instrument for driving vectors into Analog Devices' high-speed Digital-to-Analog converters. The DPG connects to a PC over USB, and allows a user to download a vector from their PC into the DPG’s internal memory. Once downloaded, the vector can be played out to an attached Evaluation Board for a specific DAC at full speed. This allows for rapid evaluation of the DAC with both generic and customer-generated test data.

DPG2:

DPG2

Features:

  • CMOS and LVDS electrical standards, at data rates up to 1.2GSPS x 32-bits = 38.4Gbps (LVDS)
  • Two channels of 16-bits each (in both CMOS and LVDS modes)
  • 512MB on-board RAM, for up to 134 million samples per channel
  • Support for interleaved data streams
  • High-speed vector download

Documentation:

The DPG2 Users Guide discusses the details of the DPG2 in more detail. It is available as a PDF online, and is also included as part of the DPG Suite Documentation (installed with the DAC Software Suite).

DAC Software Suite:

The DAC Software Suite contains all the software required to run a DPG2. Included in the suite:

  • DPGDownloader: a graphical interface for generating simple vectors and downloading saved vectors into a DPG2.
  • VisualAnalog Interface: allows downloading vectors directly to the DPG2 from within VisualAnalog.
  • Matlab Interface: download vectors into a DPG2 directly from Matlab
  • LabVIEW Interface: control and download vectors from within LabVIEW 7 and 8.5
  • USB Drivers: drivers for both the DPG2 and high-speed DAC evaluation boards with USB

System Requirements:

  • Windows® XP (SP2 recommended) or Windows® Vista PC
  • USB 2.0 port
  • Microsoft .NET Framework 3.5 (installed during setup if not already installed)
  • National Instruments' NI-VISA 4.3 (installed during setup if not already installed)

Installation:

Two versions of the installer for the DAC Software Suite are available. The Full Installer contains all the required pre-requisites needed to install the suite on a new machine. If you have never installed the suite before, it is recommended that you download this version. The download is quite large, however.

If you have installed a previous version of the suite, the prerequisites are already installed on your computer. To upgrade, you can download the Minimal Installer, which is much smaller.

Installation guides are available here.

Downloads:

Download the Full Installer (Version 1.1.3323.32786, Updated 2/5/2009) (exe, 174 MB)
Download the Minimal Installer (Version 1.1.3323.32786, Updated 2/5/2009) (exe, 15.9 MB)

Documentation:

The DPG Suite Documentation contains documentation on the numerous software interfaces available for communicating with the DPG2.
