Test level with Burst as per IEC 61000-4-4 Ed.2.
Burst generators, which comply with the specifications of IEC 61000-4-4 Ed2: 2004, have a limitation of the
maximum output voltage. Then the maximum test level is limited by the number of coupling on several lines.
Please see the following limits:

Decoupling inductors for surge pulse
To prevent unwanted voltage drops in the coupling/decoupling networks, the value of the decoupling element
generally must be reduced for coupling/decoupling networks rated at >25 A. The Table below shows the reduced
inductor values per line in function of the rated current.
Rated current
Inductance per line
16 A
1.5 mH
32 A
0.75mH
63 A
0.6mH
100 A
0.6mH
200 A
0.3mH
For this case, the “time to half value” of the open-circuit voltage waveform may be reduced in accordance with
Tables 6 and 7 in standard IEC 61000-4-5.
