GT3X include a combination of Axis 1 and Axis 2 or Axis 1, Axis2, and Axis 3. GT3X+ devices collect data from all three

axes regardless of configuration. Error! Reference source not found. illustrates each device’s orientation while Table 8

Memory Size and Data Storage defines which devices support multi axis data collection.

For standard epoch values (non-raw data epoch collection intervals), accelerometer data is sampled at a rate of 30Hz,

passed through ActiGraph’s proprietary filter algorithm, then accumulated until the end of an epoch window is reached.

For instance, devices set to collect data at 1-second epochs will store a sum of 30 filtered samples per epoch.
