Measurement Modes
6.1
Single Magnetic Probe
The three magnetic field components Bx
0
, By
0
and Bz
0
from pixel 0 can be measured in one
measurement cycle by using the single probe mode.
6.1.1
Application Example
Magnetic vector components of Pixel 0 in probe mode.
The actual sensors are placed at the bottom side of the IC.
