The sampling rate of the analog inputs is up to 216 kHz per channel. A 4 mA current source for the IEPE/ICP sensor, AC or DC coupling and gains of 1 and 10 are all individually programmable per channel. Output signals with a voltage level of ±3 V can also be generated at an output rate of up to 216 kHz. In addition, the DT9847 modules provide eight digital I/O channels. All inputs and outputs can be run simultaneously.
The modules are powered by USB or a 5-24 VDC external power supply, depending on the model. A Sync Bus (RJ45) connector allows connecting and synchronizing up to four modules to create a powerful measurement system for audio, acoustic or vibration analysis, with up to 12 analog inputs and up to eight 32-bit signal outputs.
The new USB data acquisition modules ship with a comprehensive software package that is compatible with Windows 7, XP and Vista. The package comprises a wide range of useful tools as well as 32/64 bit drivers for the SDK, .NET, LabVIEW and MATLAB. In addition, Data Translation’s VIBpoint Framework offers a software spectrum analyzer that has been built around the functionality of all sound and vibration data acquisition modules from Data Translation.
