Option
Loop sensor/radiating loops
Field loops are required to generate magnetic fields. Magnetic fields are measured
with sensor loops. The loops are manufactured according to the definitions in MILSTD 461 and EN 55103.
Helmholtz coil Helmholtz coils are the ideal instruments for generating homogeneous magnetic
fields. The models HCS_50/28 and HCST_50/28 generate field strengths from
1000 A/m to 1 kHz. The MGA 1033 with the optional compensation board is
required for this.
Coupling transformer A coupling transformer is used for testing for conducted immunity on power lines
according to MIL-STD-461, CS 101. Due to the high common-mode voltage on the
mains side, a differential amplifier is built into the coupling transformer, which
enables simple measurement of the coupled differential voltage.
Testing equipement
acc. To EN 55103-2
Annex B of EN 55103-2 describes various test adapters intended for immunity tests
from 50 Hz to 10 kHz.
