Enhancement of accuracy for measuring the susceptibility of integrated circuits to conducted electromagnetic disturbances

An original and reliable prototype injection setup has been developed in order to carry out accurate conducted susceptibility measurements up to 1.5 GHz. The prototype has been proposed as an alternative solution to typical injection setups such as a coupling capacitor, bias tee or cross-talk system, frequently used with the direct power injection standard IEC62132-4. Simple to build and mechanically sound, the prototype injection setup is used to merge continuous conducted electromagnetic disturbances with wanted signals by using merely a semi-rigid coaxial cable. It offers good stability on a wide frequency range. Furthermore, it is neither expensive nor complicated to build.
