Electrical Fast Transient (EFT)/Burst generators are required for conducted immunity testing standards like IEC/EN 61000-4-4 and others. The EMC Shop stocks all types of EFT/Burst generators for compliance and pre-compliance testing. Rent or buy (EFT)/Burst generators for individual tests or multifunction generators to complete an assortment of tests in a compact solution. Most systems can be easily upgraded to include additional tests as required.

(EFT)/Burst generators are typically benchtop, but heavy equipment. When doing testing on three phase power lines systems usually require much larger coupling/decoupling networks which substantially increase system size. EM test environments with ground planes with connections to earth are required to safely use transient generators.
Common EFT/Burst Generator Tests
A typical burst has a single pulse rise time/duration of 5 ns/50 ns from a source impedance of 50 Ω
Bursts of 15 ms duration with a repetition rate of 5 kHz (or 100 kHz) are applied every 300 ms
The standard defines four basic test levels, all with repetition frequencies 5 or 100 kHz
The level voltage depends on equipment being tested:
Power ports: 0.5 , 1, 2, 4 kV
Signal and control ports: 0.25, 0.5, 1, 2 kV
