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.

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.

Near Field Probes 30 MHz up to 3 GHz
RF2 set
The RF2 near field probe set consists of 4 passive near field probes for measurements in the development phase of the magnetic field in the range from 30 MHz to 3 GHz on electronic assemblies. The probe heads of the RF2 set allow the step by step localization of interference sources of the RF magnetic field on assemblies. From greater distances the electromagnetic interference can be detected by RF-R 400-1 and RF-R 50-1 probes. The RF-B 3-2 and RF-U 5-2 probes with their higher resolution can more precisely detect the interference sources. Field orientation and field distribution on an electronic assembly can be detected through a trained special use of the near field probe. The near field probes are small and handy. They have a sheath current attenuation and are electrically shielded. They can be connected to a spectrum analyzer or an oscilloscope with a 50 Ω input. They do not have an internal terminating resistance.

Inductive Sensors
Inductive Proximity Switches, self contained, depend on the output of an oscillator for their operation. The oscillator resonant circuit uses an open core coil to produce a concentrated high frequency electromagnetic (RF) field, which emerges from the active surface of the sensor. If a metal target (or other electrically conductive material) enters this field, eddy currents will be induced in it, causing the resonating oscillator to be damped.

EM Tracking Products
The strength of the Aurora and 3D Guidance electromagnetic tracking solutions lies in their similarities and their differences. Both can provide unobstructed in-vivo tracking of OEM medical instruments, share exceptional measurement accuracy and reliability and are engineered and manufactured to deliver unparalleled tracking performance. Between them, there are seven different field generators with unique measurement volumes, and 20 standard sensor offerings (plus custom options). While the Aurora has 6DOF and 5DOF sensors, the 3D Guidance solution specializes in 6DOF tracking. 6DOF sensors are usually re-processable; 5DOF can be disposable. Some of our field generators are portable, while others seamlessly integrate into the medical OEM’s procedural cart or operative table. These differences provide near-countless opportunities to customize and integrate the Aurora and 3D Guidance solutions – all while benefiting from a shared foundation of technical excellence and expert product execution.

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.
