    The pulse train generator SGZ 21 generates zero-potential pulse-like interference signals with electrically isolated symmetrical outputs. The current pulse of SGZ 21 can be partly coupled with components, cables, shielding or grounding system; can be injected into the module, or indirectly coupled into the device under test through field source coupling. The SGZ 21 has a built-in pulse density counter that measures the signal generated by the module via the optical input port.

    During burst testing with the S31 sensor mounted on the component, the electrical signal from the component is converted into an optical signal. The pulse rate counter of SGZ 21 detects these light signals. In addition, the MS02 magnetic field probe measures pulsed magnetic fields on components and converts them into optical signals during testing. This measurement procedure is suitable for signal monitoring during burst tests or for controlling EMC steps before and after the measurement. SGZ 21 complies with the following standards: EN 50 081-1/-2 and EN 50 082-1/-2.

  • main feature:

    Apply interference current to the device under test or a part of the device under test;

    Generate an electric field between the device under test and the environment (screen, metal chassis or structural parts);

    Connection of very small field sources (only a few mm²) for precise location of interference-prone areas.
