DT9857E

High Channel Count Sound and Vibration DAQ

The DT9857E is a high accuracy dynamic signal acquisition module for noise, vibration, and acoustic measurements. Eight or sixteen, 24-bit, IEPE (ICP®) sensor inputs are synchronized with a tachometer input, two measurement counters, and a general purpose counter/timer to provide data streams that are matched in time, for field or laboratory use. Two stimulus D/A outputs, each 32-bit resolution, and an 8-bit digital output port are available for dynamic waveform generation and control. This rugged, compact module, available either as an OEM board or steel-encased module, connects via USB making them ideal for many measurement applications.

Key Features:

Simultaneous IEPE analog inputs, waveform stimulus analog outputs, tachometer synchronous with input data stream, advanced pre and post triggering, 16 DIO (8 in/8 out), synchronous counter/timers, and Sync Bus for up to 256 A/D channels and 32 D/A channels.
All inputs and outputs can be synchronized for measurement data coherence...
- Supports the ability to return the value of the digital input port, tachometer, measure counters, and general-purpose counter in the analog input data stream, all synchronous with analog input data stream…providing correlation of tachometer or any digital input with analog signals.
Eight (DT9857E-08) or sixteen (DT9857E-16) Simultaneous, IEPE inputs, 4mA at 24V compliance, all inputs use 24-bit Delta-Sigma A/D converters for high resolution measurement to 105.6kHz, AC or DC coupling.
Two 32-bit D/A converter output channels for stimulus or waveform generation to 216kHz.
Start trigger (software, threshold, external, or Sync Bus) for acquiring post-trigger samples; reference trigger for acquiring pre/post trigger samples.
Analog threshold trigger on any of the analog input channels to program the threshold value from –10V to +10V.
SyncBus connector for synchronizing acquisition and waveform stimulus on up to 16 DT9857E modules
External 4.75V to 28V Power Supply

QuickDAQ - Data Logging and FFT Analysis Software
QuickDAQ allows you to acquire and display from all Data Translation USB and Ethernet data acquisition 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 The Mathworks MATLAB® for more advanced analysis. Two additional upgrade options can be purchased to add FFT analysis capabilities to the base package.
