Possibilities for analysis at a free field

TEM Cell and µ-TEM Cell

Other measurement technologies:

Electro-optical field sensor system up to 3 GHz
ILS-VOR receiver for analysis
Impedance Analyzer (4 Point-Bridge Circuit) from 40 Hz to 110 MHz including BIAS-Tee for Bias-Currents up to 1kA
Bit Error Rate Tester (BERT)
Power Quality measuring device technology incl. transient acquisition

Software:

Numerical programs for field computation based on MoM (Concept) and FEM with time domain and frequency domain solver (CST-Microwave Studio)
In order to control the meters needed in our projects we develop demand-actuated software using mainly LabView and MATLAB. Part of the gathered data is immediately analysed and saved applying EXCEL. Thus automatized measurements are realised fast and securely.

Other Equipments:

Two measurement vehicles for external measuring campaigns; one of them is equipped with a 10 kW three-phase generator in order to implement measurments autonomously from access to a power grid.

Further activities:

Consulting : Advisory activities embrace problems arising during development as well as production processes. The extent of those activities varies since they are applied individually.

Expert opinions: concerning the whole field of EMC can be furnished (e.g. problems with displays under magnetic field exposure, ESD, grounding, shielding, radiated EMC).

Cooperation in committees for EMC standardisation: DKE, CISPR, IEC, EUROCAE
