Sound And Vibration Analysis DAQ

The Digilent DT9857E-8-xAO is a USB-based, high-speed dynamic signal analyzers with 8 simultaneous 24-bit IEPE sensor inputs, up to 105.4 kS/s/ch sample rate, one tachometer input, and 16 digital I/O. It features built-in IEPE signal conditioning for direct measurements from sensors like accelerometers and microphones.

DT9857E Series

The DT9857E represents a series of dynamic signal acquisition (DAQ) modules that are highly precise and are used for measurements of noise, vibration, and acoustics. These modules can have either eight or sixteen 24-bit IEPE (ICP) sensor inputs that are synchronized with an input from a tachometer, two counters for measurement, and a counter/timer for general purposes, all to provide time-matched data streams for use in the field or laboratory. They can have up to two D/A outputs for stimulus, each with a resolution of 32-bit, and an 8-bit digital output port for the generation and control of dynamic waveforms. These robust, compact modules can be obtained as an OEM board or as a module encased in steel, and they connect via USB, making them suitable for a wide range of measurement applications.

Additional Highlights

• Up to four DT9857E modules can be synchronized to measure 64 analog inputs and 8 analog outputs
• DIN Connector for 4.75 V to 28 V power
• 6 layer board provides internal grounds to maintain signal integrity
• 16 IEPE Inputs: 8 on top board and 8 on bottom board. Each IEPE input: up to 4 megohm at 24 V compliance accommodates most accelerometers
• Capacitor notch minimizes error voltages due to vibration or board stress
• Includes QuickDAQ (Free) an out-of-the-box software application for data logging, visualization, and signal generation. Two QuickDAQ upgrades are available and offer FFT analysis functions (License Required).
• Drivers are included for the most popular applications and programming languages including Visual C++, Visual C#, Visual Basic.NET, DASYLab, LabVIEW, and MATLAB.
