Signal generators for CW, AM and FM signals up to 20 GHz
Arbitrary waveform generator with maximum sampling rate of 65 GSA/s
Amplifier technology for Electromagnetic Immunity Measurements over 200 V/m up to 8 GHz

HF measurement technology

Vector Network Analysers from 10 Hz to 24 GHz, 2 and 4 port
EMI Test Receiver / Spectrum Analyser up to 40 GHz
Oscilloscope to 6 GHz
Time Domain Reflectometer (TDR)

Available measurement environments

Shielded room (fieldvariable chamber respectively electromagnetic reverberation chamber) in the dimensions 11,0 x 7,6 x 7,1 m³ for electromagnetic immunity measurments at high field strengths (200 V/m, higher field strength possible if required)
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 1000 A
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 opinion

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
