Ring Wave Immunity 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.

Ring Wave Immunity Generator Tests

For compliance, the ring wave has a measured 0.5 us rise time and 100 kHz oscillation frequency This impulse is commonly used for applications related to power distribution and railway environments.
