Introduction：
The FESP 5133-9 Circular Shielded Radiating Loop Antenna is a test instrument manufactured by Schwarzbeck, Germany and distributed by EUTTEST that generates magnetic fields up to 400 A/m in a short period of time. It is designed to generate defined magnetic field strengths in the audio frequency range up to 3 MHz. The main test standard is the immunity test for magnetic fields, e.g. VG 95377 Part 13.
It can also be used to measure the magnetic field around the equipment installed in the field, open-circuit output voltage is proportional to the magnetic field strength (at a fixed frequency) or proportional to the frequency (at a constant magnetic field strength), and should be connected to the 50 Ω spectrometer and receiver when measuring the magnetic field.
