A new USB data acquisition module from Data Translation comes with 32 analogue inputs, a 1 MHz A/D converter and 20-bit A/D resolution. The DT9844 is designed to provide high throughput and high accuracy for a large number of channels. Even at the maximum overall sampling rate of 640 kHz, the module achieves an outstanding system accuracy and minimises noise and crosstalk. In addition to the 32SE or 16DI analogue inputs, the module also features 32 digital I/O channels and five counter/timers.
The module's accuracy is achieved by a wide analogue bandwidth of the input subsystem, a high-speed multiplexer and a powerful A/D converter. The new ±500V tri-sectional galvanic isolation between the analogue inputs, the digital I/O channels and the USB interface ensures ultra-accurate measurements.
All analogue channels can be run simultaneously and synchronously with the digital I/O channels. The digital outputs can also be used for synchronising external devices. In addition, the module provides flexible trigger functions with pre- and post-triggers and an external clock input.
The new USB data acquisition module is available as a rugged STP connection box and as an OEM embedded version.
The included QuickDAQ measurement software offers a complete, ready-to-measure data acquisition solution. QuickDAQ provides data acquisition, display and logging functionality and allows the export of data to Excel for more advanced analysis. The module also ships with a comprehensive software package comprising 32/64-bit drivers for the standard Windows operating systems and a wide range of software tools, such as interfaces for LabVIEW, MATLAB and .NET.
