CA EFT KIT

The pulse shape of EFT/burst generators designed as per IEC 61000-4-4 have to be verified both into a 50ohm and a 1,000ohm load at the 50ohm coaxial HV output as well into 50ohm load at the output of the coupling network where the DUT is connected when testing mains supply lines.
The CA EFT kit includes the load resistors and a set of adapter to connect the coaxial matching resistors appropriately to the DUT output port.

Open circuit voltage setting at the EFT/burst generator
(50ohm output): 2,000V

Resulting output voltage across the 50ohm matching resistor: 1,000V

Measuring voltage Vm: 10V

Measured voltage considering the 50ohm input impedance of the oscilloscope: 5V

Resulting attenuation (theoretical): 400:1

Open circuit voltage setting at the EFT generator (50ohm output): 2,000V

Resulting output voltage across the 1,000ohm matching resistor: 1,000V

Measuring voltage Vm: 4V

Measured voltage considering the 50ohm input impedance of the oscilloscope: 2V


Resulting attenuation (theoretical): 1,000:1
