Check Text ( C-39646r9_chk )
Check for minimum separation between any RED processor and BLACK equipment IAW the following guidance: A separation distance of 1 meter (39 inches) shall be provided between RED equipment and: 1. BLACK wirelines that connect to RF transmitters; and 2. BLACK equipment with lines that connect to RF transmitters. A separation distance of 30 cm (12 inches) shall be provided between RED Equipment and BLACK wirelines that directly leave the inspectable space. NOTES: 1. This requirement is applicable in a tactical environment. 2. The supporting Certified TEMPEST Technical Authority (CTTA) should always be contacted for specific separation requirements, which may be greater than the distance reflected in this check. 3. Inspectable Space is the three dimensional space surrounding equipment that processes classified and/or sensitive information within which TEMPEST exploitation is not considered practical or where legal authority to identify and remove a potential TEMPEST exploitation exists and is exercised. CTTAs have the authority to define the inspectable space.
