A dynamic signal acquisition module for USB features high-performance, 24-bit resolution and is specifically designed for audio testing, acoustic measurement and vibration analysis applications. The DT9837C from Data Translation is available as a board-level OEM version for embedded test applications, or installed in a metal mini-XLR or BNC connection box for easy sensor connections. All Data Translation devices include comprehensive driver and software support, enabling developers to get their applications up and running quickly. 

Combine the DT9837C with the ready-to-measure VIBpoint Framework to create a powerful FFT Analyzer instrument at a much lower cost. The 24-bit D/A stimulus of the DT9837C precisely matches the input A/D sampling rates for measuring transfer functions up to 96 kHz, a requisite for high-quality acoustic, audio and vibration test and measurement,” according to Fred Molinari, President and CEO.   

Key design features include four simultaneous 24-bit Delta-Sigma A/D channels for high-resolution measurements along with support for integrated electronic piezoelectric (IEPE) inputs, including use of a 2 mA current source and AC or DC coupling, to interface with an accelerometer and microphone. The Input range is ±10V with software selectable gains of 1 and 10 for an effective input range of ±10V and ±1V with throughput rates of up to 105.4 kHz per channel. The included drivers and software are compatible with Windows XP/Vista/7. The VIBpoint Framework support software is available in a free 14-day trial version.
