• Dynamic signal acquisition module for noise, vibration, and acoustic measurements
• Four simultaneous IEPE inputs
• 24-bit resolution
• 105.4 kS/s/chsample rate
• No external power required – runs on USB power 

The Digilent MCC DT9837B is a USB-based dynamic signal analyzer with four simultaneous 24-bit IEPE sensor inputs, 105.4 kS/s/ch sample rate, and one tachometer input. The MCC DT9837B features built-in IEPE signal conditioning for direct measurements from sensors such as accelerometers and microphones.

The DT9837 series high-accuracy dynamic signal acquisition modules are ideal for portable noise, vibration, and acoustic measurements. The rugged compact modules are USB powered making portable measurement applications possible.

Software support includes QuickDAQ, an out-of-the-box application for data logging, visualization, and signal generation. Drivers are included for the most popular applications and programming languages including Visual C++, Visual C#, Visual Basic.NET, DASYLab, LabVIEW, Linux, and MATLAB.

Applications that require accelerometer, vibration, noise, or sonar measurements often use IEPE sensors. IEPE conditioning is built-in to the analog input circuitry of the DT9837 Series modules. The modules support the following software programmable IEPE functions for each of the four analog inputs:

Excitation current source - provides an internal excitation current source of 4 mA.

Coupling type - AC coupling or DC coupling can be selected.

The DT9837 Series modules support an internal clock, which is derived from the USB clock. Use software to specify the internal clock source and the frequency at which to pace the input and output operations and to start the sample clock. For the DT9837B, the sampling frequency ranges from 195.3 Hz to 105.469 kHz.
