Part number:6069-410-147
USB Dynamic Signal Analyzer; 24-bit, 216 kHz, 2 IEPE AI, 2 AO.

The DT9847 Series are high-accuracy, dynamic signal acquisition modules designed for sound and vibration applications. 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.Combine the DT9847 with the ready-to-measure QuickDAQ application to create a powerful FFT Analyzer instrument. Additionally, all Data Translation devices include comprehensive driver and software support, and interface tools for LabVIEW™ and MATLAB® programmers.

Analog Input Channels
The DT9847-2-2 module provides two analog input channels and the DT9847-3-1 module provides three analog input channels. These are single-ended channels; IEPE sensors can be connected to these inputs. Software-selectable gains of 1 and 10 provide effective input ranges of ±10 V and ±1 V. The DT9847 Series modules use 24-bit Delta-Sigma analog-to-digital converters (ADCs) that provide anti-aliasing filters based on the clock rate. These filters remove aliasing, which is a condition where high frequency input components erroneously appear as lower frequencies after sampling. DT9847 Series modules can acquire a single value from a single analog input channel, a single value from all the analog input channels simultaneously, or multiple values from a group of analog input channels.

IEPE Functions
Applications that require accelerometer, vibration, noise, or sonar measurements often use IEPE sensors. IEPE conditioning is built-in to the analog input circuitry of the DT9847 Series modules. The modules support the following software-programmable IEPE functions for each of the analog inputs: • Excitation current source — The DT9847 Series modules provide an internal excitation current source of 4 mA. Enable or disable the use of a 4 mA, internal excitation current source using software. By default, the excitation current source is disabled. • Coupling type — Select whether AC coupling or DC coupling is used. By default, DC coupling is selected for the DT9847 Series modules.Exceptional performance of the DT9847 is illustrated in the FFT diagram. The D/A stimulus signal of ±20 µV at 4.98 kHz is fed back into the A/D input. The A/D is sampling at 50 kS/s/ch.The IBF (input Below Full Scale) is –113.6 dB, the signal-to-noise plus distortion is –9.12 dB, the ENOB (Effective Number of Bits) is 17.1.

Programmable A/D Clock
The DT9847 Series modules support an internal clock, which is derived from the USB clock. Use software to specify the internal clock source and the frequency at which to pace the input and output operations and to start the sample clock. The sampling frequency ranges from 1 kHz to 216 kHz.
