The pulse shape of fast damped oscillatory generator designed as per IEC 61000-4-18 have to be verified both into a 0.1ohm and a 1,000ohm load at the 50ohm coaxial HV output as well into 0.1ohm load at the output of the coupling network. The CA OCCS F kit includes the load resistors and a set of adapter to connect the coaxial matching resistors appropriately to the DUT output port.
