Sound (Noise) and vibration measurements often require high-resolution digitizers to capture the necessary signal details. The Data Translation’s DT9837 Series high accuracy dynamic signal acquisition modules are ideal for portable noise, vibration, and acoustic measurements. Four, 24-bit, IEPE (Integrated Electronic Piezoelectric) sensor inputs are synchronized with a tachometer input (depending on the model selected) to provide data streams that are matched in time, for field and laboratory use. These rugged, small modules are USB powered, making them ideal for portable measurement applications.

Key Features of DT9837 Sound & Vibration Analyzer

  • Bus-powered for portability
  • Four Simultaneous, 24-bit Delta-Sigma A/D channels for high resolution measurements
  • Support for IEPE inputs, including use of a 4 mA current source (2 mA for DT9837C) and AC or DC coupling
  • Up to 105.4 kHz sampling rate per channel
  • Tachometer input support in the A/D data stream for synchronizing measurements (no tachometer on DT9837C)
  • For DT9837A modules only, support for reading analog output values in the analog input data stream, to correlate input and output values
  • One 24-bit D/A converter (DT9837, DT9837A, and DT9837C only)
    • For the DT9837 module, waveform capability of up to 8,192 samples; for the DT9837A and DT9837C modules: single value, waveform, and continuous streaming output
    • For the DT9837, output rate fixed at 46.875 kS/s; for the DT9837A, programmable output rate from 10 kS/s to 52.734 kS/s; for the DT9837C, programmable output rate from 10 kS/s to 96 kS/s 
  • For DT9837A, DT9837B, and DT9837C modules only, an RJ45 synchronization (LVDS) connector for synchronizing acquisition on multiple modules
  • Software and drivers compatible with Windows XP/Vista/7
  • Ready-to-run VIBpoint Framework application support
