The figure describes the AM7164 and the GT3X + with and without the Low Frequency Extension (LFE) option disabled accelerometer. The plot is the output as a function of the frequency at short radius (22 mm) of oscillation (A) and long radius (49 mm) of oscillation (B). Frequency is expressed as s-1 and the average acceleration in ms-2. The results are presented as means. The scales differ between radii of oscillation.
