4 one 50-pin, one 68-pin a. This throughput is for a single analog input channel.

b. This throughput is for full-scale ranges.

• Programmable bipolar (±10 V) and unipolar (0 to 10 V) input ranges with gains of 1, 2, 4, and 8; fixed output range of ±10 V

• Continuously-paced and triggered scan capability

• A 1024-location channel list that supports sampling analog input channels at the same or different gains in sequential or random order

• Up to 256 scans per trigger for a total of 262,144 samples per trigger

• PCI bus mastering for data transfers

• Pre-, post-, and about-trigger acquisition modes to acquire data relative to an external event using computer memory

• Internal and external clock sources; one external clock input for the analog input subsystem and one external clock input for the analog output subsystem

• Analog threshold triggering using either an external analog input or one of the analog input channels; a separate DAC sets the trigger level (8-bit resolution, fixed hysteresis)

• Digital TTL triggering; one external hardware TTL input for the analog input subsystem and one external hardware TTL input for the analog output subsystem

• Simultaneous analog input and analog output operations running at full speed

• Software calibration of the analog input and output subsystems

• Two 8-bit digital ports programmable as inputs or outputs on a per-port basis; digital inputs can be included as part of the analog input channel list to correlate the timing of analog and digital events; digital outputs can drive external solid-state relays

• Two dynamic, high-speed digital output lines; useful for synchronizing and controlling external equipment, these dynamic digital output lines are programmable as part of the analog input subsystem using the DataAcq SDK

• Programmable gate types

• Programmable pulse output polarities (output types) and duty cycles

• A/D Sample Clock Output and A/D Trigger Output signals, useful for synchronizing and controlling external equipment

Supported Software

The following software is available for use with the DT3034 boards and on the Data

Acquisition OMNI CD:

• DT3034 Device Driver – The device driver is installed automatically when you install the software from the Data Acquisition OMNI CD. You need the device driver to use the

DT3034 board with any of the supported software packages or utilities.

• The Quick DataAcq application – This application provides a quick way to get a DT3034 board up and running. Using the Quick DataAcq application, you can verify the features of the board, display data on the screen, and save data to disk.

• The quickDAQ application – An evaluation version of this .NET application is included on the Data Acquisition OMNI CD. quickDAQ lets you acquire analog data from all devices supported by DT-Open Layers for .NET software at high speed, plot it during acquisition, analyze it, and/or save it to disk for later analysis.

• DT3034 Calibration Utility – The DT3034 Calibration Utility allows you to calibrate the analog input and analog output subsystems of the DT3034 board. Refer to

page 123 for

more information on this utility.

• Measure Foundry –

An evaluation version of this software is included on the Data

Acquisition OMNI CD. Measure Foundry is drag-and-drop test and measurement application builder designed to give you top performance with ease-of-use development.

Order the full development version of this software package to develop your own application using real hardware.

• DT-Open Layers for .NET Class Library – Use this class library if you want to use Visual

C# or Visual Basic for .NET to develop your own application software for a DT3034 board using Visual Studio 2003 or Visual Studio 2005; the class library complies with the

DT-Open Layers standard.

• DataAcq SDK – Use the Data Acq SDK if you want to use Visual Studio 6.0 and Microsoft

C or C++ to develop your own application software for a DT3034 board using Windows

XP, Windows Vista, or Windows 7; the DataAcq SDK complies with the DT-Open Layers standard.

• DTx-EZ – DTx-EZ provides ActiveX controls, which allow you to access the capabilities of the DT3034 board using Microsoft Visual Basic or Visual C++; DTx-EZ complies with the

DT-Open Layers standard.

• DAQ Adaptor for MATLAB – Data Translation’s DAQ Adaptor provides an interface between the MATLAB Data Acquisition (DAQ) subsystem from The MathWorks and

Data Translation’s DT-Open Layers architecture.

• LV-Link – An evaluation version of LV-Link is included on the Data Acquisition OMNI

CD. Use LV-Link if you want to use the LabVIEW graphical programming language to access the capabilities of the DT3034 boards.

Refer to the Data Translation web site (www.datatranslation.com) for more information on the appropriate software package for your application.

Accessories

The following optional accessories are available for a DT3034 board:

• DT740 screw terminal panel – Screw terminal panel with two connectors to accommodate the analog I/O, digital I/O, and counter/timer signals provided by the

DT3034 board.

• EP307 cable – A 1-meter, twisted-pair, shielded cable that connects the 50-pin analog I/O connector (J1) on the DT3034 board to the J1 connector on the DT740 screw terminal panel.

• EP308 cable – A 1-meter, twisted-pair, shielded cable that connects the 68-pin digital I/O connector (J2) on the DT3034 board to the J2 connector on the DT740 screw terminal panel.
