post-process data.

1. Precondition the DUT by executing magnetic calibration trajectory leaving DUT in AZ = + 1

orientation (See Matlab Stimulus/Expected Response + Hardware

2. Rotate DUT around the z-axis from 0 to 360 degrees with an increment step of 10 degrees as

follows

3. Program rate table with desired steps and maximum velocity

a. Rotate tabletop by 10 degrees over 0.5 second per

b. Pause 0.5 seconds

c. Read orientation

d. Repeat steps a-c above until 360 degrees is reached.
