Maxim Instruments offers a wide range of Combination Wave generators with different output voltage ranges for various test requirements.

Surge pulses occur due to direct or indirect lightning strokes to an external (outdoor) circuit. This leads to currents or electromagnetic fields causing high voltage or current transients. 

Another source for surge pulses is switching transients originating from switching disturbances and systems faults. 

Due to the characteristic of the phenomenon nearly every electrical device may suffer from such lightning events which justify the necessity of surge tests being widely performed. Surge voltage can reach several thousands of volts and surge current is seen to reach several thousands of amps.
