Synchronized, Portable USB Module for Sound and Vibration
The DT9837A is a highly accurate USB data acquisition module that is ideally suited for portable sound and vibration measurement and analysis. 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. A read-back channel from the analog output guarantees perfect correlation of all signals in the input stream, the output stream, and the tachometer.
This rugged small module is self powered via the USB connection to a PC or laptop, no external power supply is needed. This makes it ideal for portable measurement applications. Additionally, two modules can be triggered simultaneously for perfectly synched measurements over eight inputs.
The DT9837A ships with a software applet to get you up and running right out-of-the-box. This applet supports basic operation of the module and can be easily modified for more advanced capabilities using Measure Foundry®, our popular rapid application builder software.
A board-only OEM version is also available.
Key Features:
- Four simultaneous 24-bit Delta-Sigma A/Ds with support for IEPE inputs including 4mA current source and AC or DC sampling.
- Portable operation, no external power supply needed.
- Tachometer input support in the A/D data stream for synchronizing measurements with two measurement modes for precise edge detection
- Programmable sampling rates from 195Hz up to 52.7 kHz
- Read-back channel for synchronization with analog inputs
- Expansion for multiple modules – Programmable Master/Slave synchronization mode
- Programmable analog threshold trigger - 0.2V to 9.8V
- Simultaneous operation of A/D and D/A subsystems for maximum performance.
- One 24-bit Delta-Sigma D/A converter for single value or ultra smooth waveform generation
