The 3340 G-Logger® Data Acquisition System is the advanced version of SDI’s Model 3330.  The 3340 incorporates all the powerful functions of the 3330, plus the 3340 is:

  • Powered by USB, AA batteries, or an AC power supply via a USB cable

  • Programmable for scheduled monitoring

  • Includes event detection and isolation during playback

  • Supports optional GPS data collection


The 3340 is the ideal tool for quick and simple evaluation of vibration and movement for use exclusively with SDI accelerometer modules and chips in test sockets.  It features three channels for input, which allows for one tri-axial module or up to three single axis modules or chips.  It also supplies all the power needed for the accelerometers, so no additional power source is needed. 


The included software features a user interface built on a LabView platform.  The 3340 acquires accelerometer data and graphically displays it simultaneously in three different formats, either in real-time or from a previously acquired data file:

  • Data versus time, like an oscilloscope

  • Spectrum, which shows magnitude versus frequency (FFT)

  • Meters, which show current measurements such as DC, RMS, and peaks


Expand or contract the time scale of the display window to see fine details or aggregate data, and pause, fast forward, or rewind the data as desired.  Record directly to a computer or a class 6 or higher SD memory card in 16-bit sample rates from 1 to 10,000 samples/second per axis.  


Automatically or manually configuring the 3340 with SDI accelerometers takes under 5 minutes, or SDI can preconfigure your 3340 at the time of purchase.  The 3340 software automatically populates the standard calibration data for compatible SDI accelerometers, or easily enter the specific data for individual accelerometers for absolute precision.  The 3340 also can perform calibration checks on demand at any time in an accelerometer’s life cycle to verify the calibration data using a simple +/-1G flip.
