2.3 Radiated Emissions Test Site Description

2.3.1 Semi-Anechoic Chamber Test Site (Buford Facility)

The Semi-Anechoic Chamber Test Site consists of a 20’ x 30’ x 18’ shielded enclosure. The
chamber is lined with Toyo Ferrite Grid Absorber, model number FFG-1000. The ferrite tile grid is
101 x 101 x 19mm thick and weighs approximately 550 grams. These tiles are mounted on steel
panels and installed directly on the inner walls of the chamber.

The turntable is 150cm in diameter and is located 160cm from the back wall of the chamber. The
chamber is grounded via 1 - 8’ copper ground rod, installed at the center of the back wall, it is
bound to the ground plane using 3/4" stainless steel braided cable.

The turntable is all steel, flush mounted table installed in an all steel frame. The table is remotely
operated from inside the control room located 25’ from the range. The turntable is electrically
bonded to the surrounding ground plane via steel fingers installed on the edge of the turn table.
The steel fingers make constant contact with the ground plane during operation.

Behind the turntable is a 3’ x 6’ x 4’ deep shielded pit used for support equipment if necessary.
The pit is equipped with 1 - 4” PVC chases from the turntable to the pit that allow for cabling to
the EUT if necessary. The underside of the turntable can be accessed from the pit so cables can
be supplied to the EUT from the pit.

2.3.3 Open Area Tests Site (Buford Facility)

The open area test site consists of a 40’ x 66’ concrete pad covered with a perforated electro-
plated galvanized sheet metal. The perforations in the sheet metal are 1/8” holes that are
staggered every 3/16”. The individual sheets are placed to overlap each other by 1/4” and are
riveted together to provide a continuous seam. Rivets are spaced every 3” in a 3 x 20 meter
perimeter around the antenna mast and EUT area. Rivets in the remaining area are spaced as
necessary to properly secure the ground plane and maintain the electrical continuity.

The entire ground plane extends 12’ beyond the turntable edge and 16’ beyond the antenna mast
when set to a 10 meter measurement distance. The ground plane is grounded via 4 - 8’ copper
ground rods, each installed at a corner of the ground plane and bound to the ground plane using
3/4" stainless steel braided cable.

The turntable is an all aluminum 10’ flush mounted table installed in an all aluminum frame. The
table is remotely operated from inside the control room located 40’ from the range. The turntable
is electrically bonded to the surrounding ground plane via steel fingers installed on the edge of
the turn table. The steel fingers make constant contact with the ground plane during operation.

Adjacent to the turntable is a 7’ x 7’ square and 4’ deep concrete pit used for support equipment if
necessary. The pit is equipped with 5 - 4” PVC chases from the pit to the control room that allow
for cabling to the EUT if necessary. The underside of the turntable can be accessed from the pit
so cables can be supplied to the EUT from the pit. The pit is covered with 2 sheets of 1/4"
diamond style re-enforced steel sheets. The sheets are painted to match the perforated steel
ground plane; however the underside edges have been masked off to maintain the electrical
continuity of the ground plane. All reflecting objects are located outside of the ellipse defined in
ANSI C63.4.

2.4 Conducted Emissions Test Site Description

2.4.1 Conducted Emissions Test Site (Buford Facility)

The AC mains conducted EMI site is located in the main EMC lab. It consists of an 8’ x 8’ solid
aluminum horizontal ground reference plane (GRP) bonded every 3” to an 8’ X 8’ vertical ground
plane.

2.4.2 Conducted Emissions Test Site (Buford Facility)

The AC mains conducted EMI site is located in the main EMC lab. It consists of a 12’ x 10’ horizontal
coupling plane(HCP) as well as a 12’x8’ vertical coupling plane(VCP). The HGP is constructed of 4’ x 10’
sheets of particle board sandwiched by galvanized steel sheets. These panels are bonded using 11AWG
1/8” x 2” by 10’ galvanized sheet steel secured to the panels via by screws. The VCP is constructed of
three 4’x8’ sheets of 11AWG solid aluminum.

The HCP and VCP are electrically bonded together using 1”x1” angled aluminum secured with screws.

The site is of sufficient size to test table top and floor standing equipment in accordance with section 6.1.4
of ANSI C63.4:2003 and 2009.

7.5.4 Sample Calculation:

RC = RU + CFT

Where:
CFT = Total Correction Factor (AF+CA+AG)-DC (Average Measurements Only)
RU = Uncorrected Reading
RC = Corrected Level
AF = Antenna Factor
CA = Cable Attenuation
AG = Amplifier Gain
DC = Duty Cycle Correction Factor

Example Calculation: Peak – Fundamental Frequency – ZPOS
Corrected Level: 87.40 - 7.84 = 79.56dBuV
Margin: 95.6dBuV – 79.56dBuV = 16.0dB

Example Calculation: Average – Fundamental Frequency – ZPOS
Corrected Level: 87.40 - 7.84 - 13.86 = 65.71dBuV
Margin: 75.6dBuV – 65.71dBuV = 9.9dB
