2.3 Radiated Emissions Test Site Description

2.3.1 Semi-Anechoic Chamber Test Site

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.

A diagram of the Semi-Anechoic Chamber Test Site is shown in Figure 2.3-1 below:

2.3.2 Open Area Tests Site (OATS)

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.

7.6.2 RF Conducted Spurious Emissions

7.6.2.1 Measurement Procedure

The RF output port of the EUT was directly connected to the input of the spectrum analyzer. The
EUT was investigated for conducted spurious emissions from 30MHz to 10GHz, 10 times the
highest fundamental frequency. Measurements were made at the low, center and high channels
of the EUT. For each measurement, the spectrum analyzer’s RBW was set to 100kHz. A peak
detector function was used with the trace set to max hold.

RF conducted spurious emissions were evaluated for all available data rates.

7.6.2.2 Measurement Results
