Tempest Specification

A good unclassified source of info is "Compliance Engineering" a
publication by Dash, Straus + Goodhue, 629 Mass Ave., Boxborough MA.  They
are an FCC/Tempest advice house, and publish an annual "how-to" guide.
The guide is wonderful reading, giving many amazing numbers.  For example,
in the '89 issue page 338 starts the article which gives the typical E vs.
time and I vs. time curves for nuke bursts (50kv/m in a 5-10 nanosecond
pulse!!!).  Basically you can kiss most of your non-shielded electronic
equipment goodby if this ever happens.
