Marlboro, Mass.Data acquisition board maker Data Translation (DT) is now shipping a less-than-$1500 data acquisition and control board. As a 2-channel-in/2-channel-out board, it's intended for price-sensitive systems.
"The E in the product designation stands for economy," says DT product manager Tim Ludy.
With sampling rates up to 100-kHz, and the ability to support uninterrupted data transfer, the DT9841E board seems optimized for many realtime engineering, industrial, lab, and scientific applications.
Indeed, DT's new DT9841E is also the lowest cost offering in its Fulcrum II Series of DSP (digital signal processor) data-acq boards. Regardless of its low price tag, it still offers quite advanced features, even at its very affordable price.
In fact, as a realtime DSP board, the DT9841E offers measurement and control performance that's about 1000 times faster than the capability of a PC-only system. It does that by leveraging the processing power of a Texas Instruments TMS320C6713 DSP chip.
The board is also equipped with a USB 2.0 (Universal Serial Bus) port that lets it communicate serially at rates as fast as 480-Mbits/s.
Complementing the TI DSP, the DT9841E packs a pair of 24-bit delta-sigma analog-input channels, with built-in anti-aliasing filters. That's just the ticket for use in noise and vibration testing applications.
The board also houses two 24-bit delta-sigma analog-output channels that can be used, for example, to stimulate systems under test. The DT9841E also includes 24 digital I/O lines that can be used for associated control and monitoring, and three 32-bit counter/timers that can be used for accurate timing tasks.
All of the board's sub-systems can also be run simultaneously and monitored in realtime, thanks to the on-board 32-bit floating-point DSP.
The DT9841E's architecture also supports autonomous operation, thanks to 2-Mbytes of on-board flash and 128-Mbytes of SDRAM. The board also provides internal and external clocks and triggers, and offers 500-V of isolation to prevent ground loops and to maximize analog signal integrity.
To get up-and-running quickly, DT's Dynamic Signal Analyzer application is included with the DT9841E module. The system's DT Measure Foundry/RT-Streaming lets you stream realtime data between your PC and the DT9841E moduleright out of the box, without any programming
If you so choose, however, graphical programming can be done using DT Measure Foundry/RT-Streaming (it supports all Fulcrum II Series boards). If you need still more flexibility, you can develop your own low-level DSP application using TI's Code Composer Studio.
Many host and DSP communication libraries are included with the board, giving you quick access to on-board functions, and communications with your host PC.
You can also purchase a DT9841E-DK startup development kit, depicted in the photo above. It consists of a DT9841E board, an EP358E accessory panel, two interconnection cables, a standard USB cable, and a power supply.
The Whole Series Gets An Upgrade
In addition to the announcement of this affordable board, Data Translation says its full line of DSP Fulcrum II Series boards have been upgraded to use TI's latest version of the floating-point TMS320C6713 chip. It runs at 300-MHz.
