Testing low level signals over various frequency ranges, commonly encountered in testing smartphone and tablet speakers, calls for precise measurement accuracy. Low total harmonic distortion (THD) has been a prime concern.
To address this, Data Translation, a designer and manufacturer of high performance USB and Ethernet data acquisition modules, released its new DT9847 Series high-accuracy, dynamic signal acquisition modules for USB.
“A key attribute of the DT9847 is the ultra-low total harmonic distortion of 102dB,” Fred Molinari, president and chief executive officer at Data Translation said in a statement.
The newly launched series is suitable 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 VIBpoint Framework 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.
Key Design Features of the DT9847 Series include; Flexible channel configurations with portable, USB-powered models available, simultaneous analog input and analog output operations, 24-bit A/D converter per channel, up to 216 kSamples/s/ch, Input range of ±10 V with software selectable gains of 1 and 10 for an effective input range of ±10 V and ±1 V, and support for IEPE (Integrated Electronic Piezoelectric) inputs, including use of a 4 mA current source with 18 V compliance voltage for AC or DC coupling.
The DT9847 Series features 32-bit D/A per channel with sampling rate up to 216 kSamples/s/ch and output ranges of ±3 V, Digital I/O: 4 input lines and 4 output lines, supports a start trigger for acquiring pre-trigger samples and a reference trigger for acquiring post-trigger samples, sync Bus (RJ45) connector for synchronizing acquisition on up to four DT9847 Series modules. Also, it comes with drivers and software and is supported by VIBpoint Framework.
The DT9847 Series is priced starting at $1595 USD and will be made available from November 2012, according to the company.
Recently, Data Translation announced new Ethernet data acquisition module extending precision measurements up to ±600V with ± 1000V Isolation.
