Designed for applying the impulse output voltage of the Combination wave/ Ring wave generator to interconnection lines of the equipment under test, acc. to IEC 61000-4-5, Fig9/ IEC 61000-4-12, Fig. 8.
The coupling/decoupling network CDN 504/ 508 U essentially consists of a current compensated decoupling inductor, L1 – L4/L8, and a set of coupling impedances to be inserted in the coupling path.
