Low-Cost USB Powered Sound and Vibration DAQ

The DT9839 is a low cost, low noise, portable USB data acquisition module. It is especially suited to measuring vibration signals for low noise performance so that results from vibration measurements are pristine and accurate.  The DT9839 has 4 separate analog input channels for simultaneous operation, each channel having a 16-bit Delta-Sigma A/D converter.   Each A/D provides inherent anti-aliasing filtering so that erroneous signals beyond the desired frequency band are eliminated.

Key Features:

  • 4 simultaneous, 16-bit Sigma-Delta IEPE analog input channels...correlated results
  • Outstanding noise performance: SINAD 91dB, ENOB 15.3, THD 0.0018%, SFDR 100
  • Fast sampling...up to 52.7 kHz sampling rate per channel
  • Tachometer:  support in the A/D data stream for synchronizing measurements
  • Flexibility...triggering modes for pre, post, or reference samples
  • Stimulus: 24-bit Sigma-Delta D/A converter with ±2.5 V range
  • USB bus-powered for portability
  • Board-level OEM version available
  • Supported by QuickDAQ ready-to-run application software

The DT9839 features outstanding noise performance at low cost. Combined with QuickDAQ software, it provides a low-cost, portable sound and vibration solution.

QuickDAQ 2013 QuickDAQ (Free)
QuickDAQ allows you to acquire and display from all Data Translation USB and Ethernet devices that support analog input streaming. Combine QuickDAQ with Data Translation hardware to acquire data, record data to disk, display the results in both a plot and digital display, and read a recorded data file. Be productive right out of the box with this powerful data logging software. Data can be exported to other applications like Microsoft Excel® and MATLAB® for more advanced analysis. Two additional options can be purchased to add FFT analysis capabilities to the base package and should be used with the Sound & Vibration series of modules to harness their full capability.
