DT9837

The DT9837 is a highly accurate USB data acquisition module that is ideal for portable sound and vibration measurements. Four 24-bit IEPE (ICP) sensor inputs are synchronized with a tachometer input to provide data streams that are matched in time for field or laboratory use. The 38 segment clock-time conversion of the Delta-Sigma A/Ds is offset in software to provide this time correlated data. The rugged small module is self-powered via the USB connection to a PC laptop. BNC connections are provided for all I/O signals for secure and easy-to-use operation.

A board-only OEM version is also available.

Key Features:

  • 4 simultaneous, 24-bit Delta-Sigma A/D channels for high resolution measurements.
  • Support for four IEPE inputs, including 4mA current source and AC or DC coupling.
  • Portable operation. No external power supply needed. Runs on USB power.
  • Tachometer input support in the A/D data stream for synchronizing measurements.
  • Sampling rate of over 52kHz to meet your application need.
  • Analog input range of +/-10V with software selectable gains of 1 and 10.
  • One 24-bit Delta-Sigma D/A converter with single-value or ultra-smooth waveform capability.
  • Programmable triggers for analog input operations for maximum flexibility. Choose a software trigger, TTL trigger, or analog threshold trigger.
  • Simultaneous operation of the A/D and D/A subsystems for maximum performance.
  • Supported by all DT-Open Layers for .NET Class Library compliant software to meet any application need.
