8-channel data acquisition front-end for high-precision Sound & Vibration measurements

The MB DAQ 8256 is an eight-channel data acquisition front-end for high-precision, multi-channel sound and vibration measurements, Squeak & Rattle testing and in-line acoustic test systems. The universal inputs allow not only the connection of voltage sensors, IEPE accelerometers and microphones, but also the acquisition of additional associated quantities such as temperature, displacement, position or pressure via current sensors with 4-20 mA output. The delta-sigma A/D converter used allows simultaneous sampling at sampling rates of up to 256kS/s per channel. The signal-to-noise ratio of up to 107dB, the low distortion factor and the very low phase deviation between the channels enable noise- and distortion-free recording of the smallest measurement signals even in harsh industrial environments.  Four additional digital inputs are available for recording frequency, speed, pulse width and quadrature encoder signals. A powerful signal processor allows pre-processing and analysis of the acquired signals. The integrated Ethernet port supports data streaming for further analysis and display in our BSR SUITE data acquisition software for Sound & Vibration analysis, NVH and Squeak & Rattle testing.

Drivers for MATLAB, Python and LabVIEW

Drivers for MATLAB, Python and LabVIEW make it easy to integrate the DAQ 8256 into your own measurement applications. TCP/IP and USB API libraries allow configuration and control of the measurement hardware and transfer of acquired data via standard interfaces. The integrated powerful signal processor allows pre-processing and evaluation of measurement data, enabling the development of stand-alone instruments without the need for an external PC. The integration of analogue inputs, digital inputs and digital outputs allows the development of customised, automated test systems.
