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.

Drum Core Inductors
-
Drum core inductors are so named as the conductor (round magnet wire) is wound directly onto the ferrite core which is shaped like a drum or spool. The wire is then connected to the core, a plastic base or metal lead frame to form the surface mount termination. Drum core inductors come in unshielded (high saturation current but potentially more EMI) and shielded constructions (lower saturation current but closed magnetic path for lower EMI). The shielded constructions use either a second ferrite core or a magnetic resin epoxy to create the magnetic shield.

EMF Measurements/EM Measurements/Electromagnetic Radiation

Holland Shielding Systems B.V.
Electromagnetic fields cause interference in electronic devices and may affect the health of people close to where the fields are generated. It is important to recognize this at an early stage in a construction process, for instance at a future construction location or while construction is already underway, so that budgets are not exceeded. By means of field-strength measurements one can chart the existing electromagnetic fields and radiation emitted by GSM, UMTS antennas and transformer spaces, to mention a few examples. These measurements can help determine the best location in the new building for rooms where sensitive measurements are to take place, e.g. in hospitals or nano laboratories. And last but not least, field-strength measurements can detect sources of interference and can be part of a scheduled check of existing screened spaces and Faraday cages.

Line Impedance Stablisation Networks (LISN)
Emissions
-
All commercial LISNs include an artificial hand connection and a transient limiter. This adds a 30dB insertion loss. A 30dB pre-amplifier is included which can be connected in the RF output feed to return the insertion loss to 0dB. All bar the heavy current LISNs are constructed in a flanged aluminium enclosure that can be bolted directly down to a ground plane (as required by standards). The underside of the enclosure is left unpainted to ensure good conductivity with the plane. The 16A and military/automotive LISNs have an RF output for each line, thus allowing parallel measurements of the emissions. This facilitates measurement of common mode and differential mode components of the emissions if required.
