the Censors allow:

6.2.2 (U) Signal Measurement Standards

              6.2.2.1 (U) AM Generators

                    6.2.2.1.1 (U) Requirements
                    6.2.2.1.2 (U) Calibration

               6.2.2.2 (U) FM Generators

                    6.2.2.2.1 (U) Requirements
                    6.2.2.2.2 (U) Calibration

7.6.2 (S) Specific RED Equipment Operation During AM and FM Tests

               7.6.2.1 (S) Test for Plain-Text Emanations
               7.6.2.2 (S) Test for Key or Keying Variable Emanations


I think 7.6.2 (and the rest of the doc) support the hypothesis that
NONSTOP
compliance means that a device does not leak when you inject (external,
RF) signals
into it, esp. during operation.  This would be in addition to TEMPEST
compliance
which assures only that the device in isolation does not spill the
beans.

As usual, the truly classified stuff would be the details ---how many
watts,
how much FM mod, etc.

NONSTOP would seem to be related to the tests that RNG builders
put themselves through, trying to see how big that White Van must be
to mess with their RNG.

Together TEMPEST/NONSTOP seem to be a crypto slant on the
FCC's "accept all evil", "emit no evil" rules for interference in
consumer devices.
