Radio frequency isolation filters shall be provided for incoming electrical power lines, including neutrals, and for incoming telephone, signal and fiber optic lines. Filters shall be supported independently of the shielding.

RF Performance Requirements After completion of this effort these efforts, the chamber shielded area and all shielded enclosures that have been modified in any way shall meet the following RF performance requirements:

1. Radio Frequency Interference Attenuation The enclosure shall have the following minimum magnetic, electric, and plane wave attenuation from:

Magnetic - 20 dB at 1 KHz rising to 100 dB at 1 MHz Electric - 70 dB at 1 KHz rising to 100 dB at 10 kHz and 100 dB from 10 kHz to 100 MHz Plane Wave - 100 dB between 100 MHz and 18 GHz The attenuation and shielding effectiveness requirements shall apply to the finished shielded enclosure and enclosure's components when all power line filters are installed and carrying current, ventilation systems are operating, the coaxial connector panels capped, and shielded doors are in normal operating position. The specified shielding effectiveness shall be achieved without using conductive tapes, gaskets, or cement materials.

This requirement shall apply to both enclosure shielding, to wiring and other interfaces utilizing penetrations into the enclosure (e.g., power and communication lines), and to all other penetrations into the enclosure (e.g., doors).

2. Radio Frequency Signal Reflections For signals incident on enclosure walls with RF reflection mitigating treatments, e.g., RAM treatments, reflected RF energy shall be attenuated by 30 dB at 500 MHz rising to 45 dB at 6 GHz an 45 dB from 6 GHz to 18 GHz. This requirement is defined to be for normally incident RF signals.

3. Radiated Emissions Radio frequency emissions (field strength at 1 meter) from all electronics, wiring and other equipment installed into the shielded enclosures shall be no greater than 60 dBuV/m (decibel microvolt per meter) at 10 kHz dropping to 24 dBuV/m at 2 MHz, 24 dBuV/m from 2 MHz to 100 Mhz, and 24 dBuV/m at 100 MHz rising to 69 dBuV/m at 18 GHz. Consult MIL-STD-461 RE-102 for more information on this requirement.

4. Radiated Susceptibility All systems and equipment installed within the chamber shielded enclosure (e.g., radar absorbent material, electronics panels, electronics wiring, and equipment connected to wiring) shall be designed or protected to withstand and operate within the chamber’s typical test RF environment. For this effort, these systems and equipment shall withstand an incident field strength of 3850 w/sq-m (watts per square meter).

Performance Test Requirements

1. Seam Leak Detection Testing Continuously test welds during fabrication using the SELDS, commonly known as a "sniffer." Upon completion of basic shielded enclosures, existing and new, before applying any metal primer or installing any accessories, test the entire shielded enclosure with the SELDS. Install terminal points on the shielding exterior and permanently attach test leads on two sets of diagonally opposing corners during construction for use with SELDS. Continuously probe seams with the test receiver set to detect abrupt changes of shielding level greater than 10 dB on the "shielding unit" scale. Clearly mark points having change greater than 10 dB and repair the weld to meet the specified requirement. Retest each repaired point until there are no points on seams which fail test.

2. Attenuation Testing The test procedures, locations, and equipment shall be as specified in IEEE Std 299, at the frequencies specified below. Perform testing as soon as possible after completion of modifications to the shielded enclosure, including installation of doors, equipment, services, power/telephone/signal lines, and RF filters. Conduct test with doors closed and the filters under normal load conditions.

Attenuation testing shall be conducted at the following frequencies: 1 Mhz, 10 Mhz, 100 Mhz, 400 MHz, 1 GHz, 10 GHz, 18 GHz Measure additional test points beyond those specified in IEEE Std 299. Test points shall include sprinkler locations, the periphery of doors and covers, handles, latches, power filter penetrations, air vent filters, telephone and control line filter penetrations, and points of penetration by pipes, tubes, and bolts.

3. RF Signal Reflections and Radiated Emissions Testing Testing of these characteristics will be performed by the Government. Radiated emissions testing will be conducted across the entire specified frequency range.

4. Radiated Susceptibility Testing Qualification of these requirements shall be by contractor-performed analysis.
