Detail

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.
