Silicon Designs: Portable Data Acquisition System

Sept. 8, 2014
The Model 3340 G-Logger is a three-channel, low cost, portable data acquisition system, offering FFT analysis and display, as well as real-time acceleration and GPS data collection and viewing.

The unit is designed to optimize the low-noise performance of all the company's single and triaxial MEMS variable capacitance accelerometers with analog output and 8-32 VDC excitation. It offers 16-bit data acquisition, with data rates of 1 to 10k samples per second and per axis, through each of its available input channels. Its user interface is built on an NI LabVIEW platform for ease of use. The unit features real-time data acquisition and readout capabilities with live streaming; real-time pause, scroll back and rewind; SD card recording and memory storage of up to 32 GB; multi-speed recording playback; and remote operation via TCP. Although acquired data is normally written to SD card, users may opt to bypass, in favor of directly streaming to a host computer. Units may also be configured to collect peak event data. The user can retrieve a list of peak events and view data in all display modes. Data can also be paused, fast forwarded, or rewound. Collected data may be also viewed in a data vs. time model, similar to an oscilloscope. This includes magnitude vs. frequency spectrum data; and meter data, showing current measurements such as DC, RMS, and peaks. Data output is displayed over a time range from 100 ms to two minutes.
