My first job (after retiring from the Army) was production EMC testing,
but TEMPEST was a government program that required it. Wang Labs had at

number of problems in the few years I was there.
Observation since has me suspecting that industry's current custom and
practice is to test as little as possible and wait for prosecutors to
discover problems.

to EMC requirements for products that are in production for a long
time? I assume that over time, the construction of e.g. capacitors
may change -- leading to
