Portable USB data acquisition system with FFT analysis introduced by Silicon Designs

KIRKLAND, Wash., 19 March 2013. Silicon Designs Inc. in Kirkland, Wash., is introducing the model 3330 G-Logger low-cost, USB-powered portable data acquisition system with powerful fast Fourier transform (FFT) analysis and display capabilities.

The three-channel model 3330 is designed to optimize the low-noise performance characteristics of all Silicon Designs single and triaxial MEMS variable capacitance accelerometer modules with analog output and 8-to-32-volt DC excitation.

The G-Logger offers 16-bit data acquisition, with data rates of 1,000 to 10,000 samples per second and per axis, through each of its available input channels.

The G-Logger's user interface is built on a National Instruments LabVIEW platform, and the device has real-time data acquisition and readout capabilities with live streaming; real-time pause; scroll back and rewind; SD-card recording of as much as 32 gigabytes; multi-speed recording playback; and remote operation via TCP. Average system setup time is less than five minutes, company officials say.

Optional offset settings enable a staggered display without overlap. An additional independent scale G/Div is available per channel, with settings that can shrink or expand channel input for better visibility.

Data output displays over a time range from 100 milliseconds to two minutes. The model 3330 data page allows for simple G readings, with as-needed real-time ability to hide or show any or all of the three measurement channels. Users may view accelerometer performance data from any remote network location.

Each G-Logger ships with all necessary Silicon Designs accelerometer specifications, along with accompanying software. As a USB-powered device, additional accelerometer power is not required.

Units measure 120 by 103 by 30 millimeters. Software is compatible with Windows XP, Vista, 7, & 8 PCs, laptops, and notebooks. For more information contact Silicon Designs online at
