I'm trying to understand the meaning of
8 x 20-µs and 10 x 1000-µs
standardized transient impulses (or sometimes it's called a waveform). But what does it actually mean. Why is there a multiplier in front of the time unit?
The quoted line above is constantly mentioned in surge testing document. But no where in the document does it mention what is the meaning of it.
Most Google search results point to Datasheet values. Maybe I'm searching for the wrong search term.
