Sound and vibration measurement system takes up to 256 channels

September 11, 2015 // By Julien Happich
For acoustic, audio, and vibration testing on large structures such as airplane wings, turbines and trucks, Data Translation now offers the possibility to combine up to four VIBboxes to a complete system providing 256 channels for IEPE/ICP sensors or voltages.

As every input has its own 24-bit A/D converter, the signals from sensors such as measurement microphones or accelerometers can be acquired simultaneously, synchronously and continuously at high sampling rates of up 51.2 kHz without time lapse or phase difference.

In addition to the 256 analog inputs, the measurement system also provides 16 tachometer inputs, as well as a wide range of counter/timers and digital I/O channels. The current source for the IEPE/ICP sensors is individually programmable for each analog input. This allows the direct connection of standard acoustic and vibration measurement sensors or the measurement of voltages in a supported range of ±10 V or ±1 V. 32 analog outputs with ultra-high 32-bit resolution can be used as signal source for any waveform stimulus.

The system ships with the easy-to-use QuickDAQ data logging application with advanced FFT-based spectral analysis capabilities.
