USB data acquisition module for audio and acoustic testing

Data Translation released the DT9837C data acquisition module, featuring four 24-bit A/D inputs and specifically designed for audio testing and acoustic measurement applications. For easy portability, the compact module is USB powered. The new DT9837C comes with software-programmable IEPE sensor functions, anti-aliasing filters, and an analogue 24-bit output for generating signals with a maximum sampling frequency of 96 kHz.

The four analogue inputs are each provided with a 24-bit Delta-Sigma A/D converter for ultra-accurate, low-noise measurements. The 2 mA current source for the IEPE/ICP sensor, AC or DC coupling and gains of 1 and 10 are all individually programmable per channel. The module is available as a board-level OEM version or installed in a compact metal connection box with mini-XLR or BNC connectors.

A synchronization connector is included for connecting and synchronizing up to four modules. This allows implementing a USB data acquisition system with 16 analogue inputs and 4 analogue outputs for sound and vibration measurement applications, with no external power supply required.

The new USB data acquisition module ships with a comprehensive software package that is compatible with Windows 7, XP and Vista. The package comprises a wide choice of useful tools and 32/64 bit drivers for SDK, .NET, LabVIEW and Matlab.
