(under construction)


Conducted EMI testing can be challenging due to the wide variety of coupling/decoupling networks that might be required for such a test.

Building these things yourself is actually quite easy once you find a suitable enclosure and know the ferrite stack that meets the impedance requirements. Unfortunately, suitable enclosures seems non-existent, so we designed a custom solution that is tailored for this purpose. We made a design that is particularly suitable for custom builds due to the open frame model and riveted connector panels. This makes machining of custom hole patterns much easier.
