3.3 Test Results

The TIDA-060040 was tested in each of the three orientations discussed previously: On-axis, In-Plane, and Off-Axis. The results from each orientation were then calibrated and a final error using controller calculations and the internal CORDIC output are shown at angle steps of 0.25° for one full rotation.
