Amund: In TEMPEST testing, both the limits and the data were considered classified information.
Don: The conflation of TEMPEST and 461 probably arose from the fact that most all equipment requiring TEMPEST compliance was being bought by DoD agencies, and they also required 461 compliance. As an example, back in the late 80’s, I did the 461 compliance testing for the SINCGARS radio system, while a TEMPEST certified engineer worked in my lab doing a parallel TEMPEST compliance test. The customer was the same, but the two efforts were on separate contracts. OTOH, I recall another job, this one commercial, where the customer only asked us to do TEMPEST on a high-speed computer line-printer; there was no requirement for 461. The customer’s plan was to sell TEMPEST ready printers to non-governmental custoers.

They were not considered overlapping requirements, and the TEMPEST engineer is looking for other things that the MIL-STD-461 engineer is not.

The EMC requirements are driven by how the item will be used. A TEMPEST qualified PC to be used around some secure data center in a plant or office building will have those sports of CISPR EMC qualifications. If the device is going to be used on a military vehicle of some sort, then MIL-STD-461 is required. But these statements stand on their own – they are independent of the TEMPEST qualification.
