Magnetometers
The strength of magnetic fields can be determined with a magnetometer. Regardless of whether in the private sector or in the work environment, the increasing use of technology and networking also increases the exposure to magnetic and electromagnetic radiation. This radiation can have a negative effect on living beings, but also on sensitive electronic devices. Many effects are so unspecific that radiation is often not recognized as the cause. With a magnetometer you can measure how strong the radiation is at your sleeping place, in the kitchen in front of the microwave or induction stove or at your workplace. The location of sensitive electronic devices such as a precision balance can be examined with the magnetometer. The extent to which the radiation intensity increases or decreases with distance can be determined by positioning the magnetometer at various distances from the radiation source.

Electromagnetic Pulse
EMP
An electromagnetic pulse (EMP) is a short burst of electromagnetic energy that can be extremely damaging to electronic equipment. EMP energy can be transferred in the form of electromagnetic radiation, an electric field, electrical conduction or a magnetic field. Since EMPs have a short duration, their impact can occur across large ranges of frequencies. EMPs can be produced naturally, occur from man-made equipment. Natural EMPs include lightning strikes and electrostatic discharges (ESD), geomagnetic storms/coronal mass ejections of solar origin. Man-made EMPs include power line surges, pulses created by ignition systems, nuclear electromagnetic pulses (NEMP) and non-nuclear electromagnetic pulses (NNEMP).

Test Fixture, Shielding Effectiveness
EM-2108 | 1.5 GHz – 10 GHz
The EM-2108 is a standard test fixture for evaluation of the electromagnetic shielding effectiveness (SE) of planar materials. The fixture is a section of coaxial transmission line broken to allow the insertion of planar test materials. Although ASTM D4935-10 is currently limited to an upper frequency of 1.5 GHz, the EM-2108 meets and complies fully with both the impedance and SE requirements called out in ASTM test method D4935-10 up to 10 GHz. These results are shown in Figures 1 & 2. The measured data relates to the shielding effectiveness due to a plane wave (far field EM wave) from which near field values for magnetic and electric fields may be inferred.

Human Exposure Measurements to Luminaries
Through different ways of coupling between luminaries and humans, a level of exposure of a person to electromagnetic fields can be derived. One part of the exposure is based on capacitive coupling between lighting equipment and person. This creates induced internal electric field that must be evaluated using an EMI receiver and a Van Der Hoofden test head.

RF Test
RF is short for radio frequency. RF is any frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space. Many wireless technologies are based on RF field propagation. These frequencies make up part of the electromagnetic radiation spectrum.

Shielding Effectiveness Test
Shielding effectiveness testing determines the ability of material to reduce the electromagnetic field in a space by blocking the field with barriers made of conductive and/or magnetic materials. Shielding effectiveness testing can be applied to a broad range of radio frequencies. Electromagnetic Shielding is typically applied to both enclosures and cables. The shielding can reduce the coupling or radio waves, electromagnetic fields and electrostatic fields. The amount of reduction can vary based on the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest. Also impacting the effectiveness of the shielding is the size, shape and orientation or apertures in a shield to an incident electromagnetic field. Electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as RF Shielding.
