Check Text ( C-49187r769928_chk )
Check that unless separated by a metal distribution system such as conduit or enclosed cable tray, a minimum separation distance of 5 cm (2 inches) or (15 cm (6 inches) for parallel cable lengths over 30 meters (98.4 feet)) is provided between any RED wire line and BLACK wire lines that exit the inspectable space or are connected to an RF transmitter, or BLACK power lines, or a digital switch (such as a computerized telephone switch or network router) that is contained within the inspectable space. NOTES: 1. This requirement is applicable in a tactical environment. 2. The supporting 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.
