Data Translation (Marlboro, MA) announced the release of the DT9847 Series high-accuracy, dynamic signal acquisition modules for USB. These modules are ideal for precision measurements with microphones, accelerometers, and other transducers that have a large dynamic range. Common applications include audio, acoustic, and vibration testing. Key features include:

  • Flexible channel configurations with portable, USB-powered models available
  • Simultaneous analog input and analog output operations (continuous or waveform mode)
  • 24-bit A/D converter per channel (up to 3 analog inputs depending on model)
  • Up to 216 kSamples/s/ch
  • Input range of ±10 V with software selectable gains of 1 and 10 for an effective input range of ±10 V and ±1 V
  • Support for IEPE (Integrated Electronic Piezoelectric) inputs, including use of a 4 mA current source with 18 V compliance voltage for AC or DC coupling
  • 32-bit D/A per channel with sampling rate up to 216 kSamples/s/ch (1 or 2 depending on model) and output range of ±3 V
  • Digital I/O: 4 input lines and 4 output lines
  • Supports a start trigger for acquiring pre-trigger samples and a reference trigger for acquiring post-trigger samples
  • Sync Bus (RJ45) connector for synchronizing acquisition on up to four DT9847 Series modules
  • Included drivers and software
  • Supported by VIBpoint Framework (available as 14-day trial version)
