“That is where a broadband “white” noise source like an emp would be ideal for finding the weaknesses of a design.”
Best to find out a design has this weakness before it is in some operational system.
That’s what the military does with respect to EMP.
Agreed. Compliance testing at an OATS.
I saw one OTAS that tested for EMP. It was in a huge facility (so that you could park a fighter jet, etc. in it and test it immunity).
Commercial electronics is vulnerable but the design has improved in recent years. I have seen the evolution. Lastly, the physical geometries of the electronics have gotten smaller which would mean that it would require higher and higher frequencies to affect its operation. Higher frequencies can be easier to control. So maybe there is an inherent immunity?
Good EMC design (as you probably know) is not a simple thing.
