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.

A diagram of the Open Area Test Site is shown in Figure 2.3-2 below:

   7       SUMMARY OF TESTS

   Along with the tabular data shown below, plots were taken of all signals deemed important
   enough to document.

   7.1      Antenna Requirement – FCC: Section 15.203

   The antenna is a monopole with -1.25dBi gain and cannot be removed without permanently
   damaging the device thus meeting the requirements of Section 15.203.

   7.2      Power Line Conducted Emissions – FCC 15.207, IC: RSS-Gen 7.2.4

   7.2.1     Measurement Procedure

   ANSI C63.4 sections 6 and 7 were the guiding documents for this evaluation. Conducted
   emissions were performed from 150kHz to 30MHz with the spectrum analyzer’s resolution
   bandwidth set to 9kHz and the video bandwidth set to 30kHz. The calculation for the conducted
   emissions is as follows:

   Corrected Reading = Analyzer Reading + LISN Loss + Cable Loss
   Margin = Applicable Limit - Corrected Reading

7.4.3     Channel Dwell Time – FCC 15.247(a)(1)(i) IC: RSS-210 A8.1(c)

7.4.3.1 Measurement Procedure

The EUT test mode does not generate a worst case channel dwell time therefore a detailed
engineering analysis is provided in the theory of operation.

As described in the theory of operation, the maximum channel transmitter dwell time is ≤ 400ms
per channel hop with the minimum period of 700ms between hops. Therefore the maximum time
of occupancy on any one channel within a 10s or 20s period is <400ms for all modes of
operation.


7.4.4     20dB / 99% Bandwidth - FCC 15.247(a)(1)(i) IC: RSS-210 A8.1(c)

7.4.4.1 Measurement Procedure

The RF output port of the EUT was directly connected to the input of the spectrum analyzer. The
span of the spectrum analyzer display was set between two times and five times the occupied
bandwidth (OBW) of the emission. The RBW of the spectrum analyzer was set to approximately
1 % to 5 % of the OBW. The trace was set to max hold with a peak detector active. The Delta
function of the analyzer was utilized to determine the 20 dB bandwidth of the emission.

The occupied bandwidth measurement function of the analyzer was used for the 99% bandwidth.
The span of the analyzer shall be set to capture all products of the modulation process, including
the emission skirts. The resolution bandwidth shall be set to as close to 1% of the selected span
as is possible without being below 1%. The video bandwidth was set to 3 times the resolution

7.5.3   Radiated Spurious Emissions - FCC 15.205, 15.209; IC RSS-210 2.2, RSS-Gen 7.2.2

7.5.3.1 Measurement Procedure

Radiated emissions tests were made over the frequency range of 30MHz to 10GHz, 10 times the
highest fundamental frequency.

The EUT was rotated through 360° and the receive antenna height was varied from 1m to 4m so
that the maximum radiated emissions level would be detected. For frequencies below 1000MHz,
quasi-peak measurements were made using a resolution bandwidth RBW of 120 kHz and a video
bandwidth VBW of 300 kHz. For frequencies above 1000MHz, peak and average measurements
were made with RBW and VBW of 1 MHz and 3MHz respectively.

The EUT was caused to generate a continuous modulated carrier on the hopping channel.

Each emission found to be in a restricted band was compared to the applicable radiated emission
limits.

Radiated spurious emissions were evaluated for all combinations of operating modes and data
rates with worst case data provided. Worst case reported was 9.6kbps.

7.5.3.2 Measurement Results

Radiated spurious emissions found in the band of 30MHz to 10GHz are reported in the Table
