DT9857E-16 USB Dynamic Signal Analyzer
Production information
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. Up to 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 64 A/D channels and up to
8 D/A channels.
All inputs and outputs can be synchronized for
measurement data coherence
o 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-8) or sixteen (DT9857E-16) Simultaneous, IEPE inputs up to 4 mA at 24 V compliance, all inputs use 24-bit Delta-Sigma A/D converters for high resolution measurement to 105.4 kS/s/ch, AC or DC coupling.
Up to two 32-bit D/A converter output channels for stimulus or waveform generation to 216 kS/s/ch.
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 –10 V
to +10 V.
SyncBus connector for synchronizing acquisition and
waveform stimulus on up to four DT9857E modules
External 4.75 V to 28 V power supply
Supported Operating Systems
• Windows® 10/8/7/Vista® 32/64-bit
The DT9857E offers many capabilities for vibration measurement such as 16 IEPE 24-bit Delta-Sigma sensor inputs, up to two 32-bit D/A stimulus outputs, a 32-bit tachometer, pre- and post-triggering. The Sync Bus allows expansion to 64 analog input channels and 8 analog output channels, and the ability to time sync all data to the input data stream.
