Radiating Loops
FESP 5139 - Radiating Loop
The magnetic, handheld coil FESP 5139 was designed to generate defined mag-netic fieldstrength in the frequency range from DC up to 5 (7) MHz. The main application is immunity testing against magnetic fields according to IEC 61000-4-39.
Depending on the current source char-acteristics magnetic fields up to 360 A/m can be generated for a short time. The generated magnetic fieldstrength is pro-portional to the coil current. A distance ring allows a precise spacing of 50 mm between coil and EUT surface. Other distance rings can be used to scale the current-fieldstrength ratio. The highest fieldstrength levels can be achieved using the shortest ring. There are further rings available on request in order to provide a certain scaling between coil current and magnetic fieldstrength (e.g. 1 A coil current = 20 A/m fieldstrength).
Application as Sensor for Magnetic Fields:
The FESP 5139 can also be used to measure existing magnetic fields. For this purpose the FESP 5139 is connected to a frequency selective 50 Ohm measuring instrument e.g. a spectrum analyzer or a measuring receiver.

FESP 5210-1 - Square Induction Coil
The square induction coil FESP 5210-1 is used to generate magnetic fields for immunity testing according to IEC 61000-4-8, IEC 61000-4-9 and IEC 61000-4-10. The edge length of the square shaped coil is 1 m. The coil comes with wing terminals, which allow a versatile and simple connection to the current source.
Operation as Helmholtz Coil:
Two square induction coil FESP 5210-1 can be combined to form a Helmholtz coil pair. The main advantages of a Helmholtz coil pair is an increase of fieldstrength and a significant improve- ment of field uniformity. For this purpose the coil planes are aligned in parallel. Electrically the coils have to be wired in series, keeping in mind that the current through the coils must flow in the same direction. This is very important to obtain the wanted addition of both fieldstrength contributions in the volume between the coils.

MFPO 9760 - Current Transformer and Pulse Generator
The MFPO 9760 is a current transformer for the typical mains frequencies of 50 Hz / 60 Hz. It is used to feed the 1 m square induction coil FESP 5410-1. This coil can reach magnetic field strengths of 1000 A/m for short time and 360 A/m continuously in its center. As this coil has only one turn it has relatively low inductance and can be used for fast signals in the time domain. On the other hand a one turn coil has a low coil factor and needs to be driven with hundreds of Ampere to reach the fields expected by IEC 61000-4-8.
The pulse generator which is built into MFPO 9760 allows defined “ON intervals” of 0.5…5.0 seconds. Other time intervals can be set by manually holding the start button longer. Alternatively the interval can be set usiing the remote input.
