Orientation of the field sources

Electric field:
The electric field is orthogonal to the ground surface (surface of the test IC) in the area of the
test IC (cf. Figure 13). Turning the field source on the spacer ring has no significant impact on the
direction and the intensity of the electric field. However, we recommend that the orientation is
selected for the measurement that was also used to calibrate the measurement set-up.
Please refer to section 3.2 for further information on the calibration of the measurement set-up.
Magnetic field:
The magnetic field is oriented in a plane parallel to the ground surface in the area of
the test IC (cf. Figure 14). Turning the field source on the spacer ring allows the user to vary the
magnetic field's direction in this plane. The orientation of the electric conductor is marked at the
bottom of the field source as an aid. In addition, there are two marks on the outer margin of the
field source that show the orientation of the electric conductor. These are visible in Figure 2 and
Figure 3 and can be used to adjust the orientation of the field source on the spacer ring. The
electric conductor and the magnetic field are perpendicular to each other in the area of the test IC.
