8.3 Burst parameter setting
The generation of high voltage bursts and high frequency pulses is part of
the EFT/burst package test required in the international standard EN/IEC
61000-4-4.
The test NSG 3040 generates bursts of interference that simulate the interfer-
ence that is generated when inductively loaded switches are operated. With
their very steep rising and falling edges, these interference pulses spread over
a frequency spectrum of over 300 MHz and may occur wherever electrical
currents are switched off in connection with motors, circuit breakers, relays,
fluorescent lamps, etc. Therefore, nearly all the relevant standards concerning
the testing of electronic equipment require the performance of burst tests.
