Efforts with simulation software helped find an off-axis placement which resulted with a peak input in the Z-direction of approximately 45 mT. The same placement results in a peak magnitude of about 32 mT in the X-direction.

Figure 4-5 Simulated Off-Axis Configuration

This configuration was then matched in a physical setup and the outputs of a single rotation were captured. Here we see fairly close behavior between the X and Z components in the simulation and the captured results.

Figure 4-6 Initial Off-Axis Measured Data

To properly configure TMAG5170 for angular measurements it was necessary to attenuate the Z component to match the X component following the procedure detailed in Sensor Calibration. Based on measurements of peak input values, a scaling factor of 67.3% was determined to be required to match peak amplitudes.
