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.

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.

7.0 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
The Cellnet 1-Way Repeater uses N-Type connectors but is a non-consumer device which is professional
installed by trained licensed technicians.

7.2 Power Line Conducted Emissions

7.2.1 Test Methodology
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

7.3 Radiated Emissions - Unintentional Radiation

7.3.1 Test Methodology
Radiated emissions tests were performed over the frequency range of 30MHz to 5 GHz. Measurements
of the radiated field strength were made at a distance of 3m from the boundary of the equipment under
test (EUT) and the receiving antenna. The antenna height was varied from 1m to 4m so that the
maximum radiated emissions level would be detected. Radiated measurements above 30MHz and below
1GHz were made with the Spectrum Analyzer’s resolution bandwidth set to 120 KHz using a Quasi-peak
detector. Above 1GHz, average measurements are taken with the Spectrum Analyzer’s resolution and
video bandwidths set to 1MHz and 10 Hz respectively. Measurements using a peak detector were also
taken above 1 GHz with Spectrum Analyzer’s resolution and video bandwidths set to 1MHz and 3MHz
respectively.

7.6 Band-Edge Compliance and Spurious Emissions

7.6.1 Band-Edge Compliance of RF Emissions

7.6.1.1 Test Methodology
The EUT was investigated at the lowest and highest channel available to determine band-edge
compliance. For this measurement the spectrum analyzer’s RBW and VBW was set to 100 kHz.

7.6.1.2 Test Results
In a 100 kHz bandwidth at the lower and upper band-edge, the radio frequency power that was produced
by the EUT is at least 20 dB below that in the 100 kHz bandwidth within the band that contains the
highest level of desired power. Band-edge compliance is displayed in Figure 7.6.1.2-1.

7.6.2 RF Conducted Spurious Emissions
The RF Conducted Spurious Emissions were measured in accordance with the FCC KDB Publication No.
558074 “Guidance on Measurements for Digital Transmission Systems (47 CFR 15.247)”. The RF output
of the equipment under test 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. For each measurement, the spectrum analyzer’s RBW was set to 100 kHz and
the VBW was set to 300 kHz. The peak detector and Max Hold function of the analyzer were utilized.

7.6.2.2 Test Results
In a 100 kHz bandwidth, the radio frequency power that was produced by the EUT emissions is at least
20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of desired
power. RF Conducted Emissions are displayed in Figures 7.6.2.2-1 through 7.6.2.2-2.

7.6.3 Radiated Spurious Emissions – Intentional Radiation (Restricted Bands)

7.6.3.1 Test Methodology
Radiated emissions tests were made over the frequency range of 30MHz to 10GHz, 10 times the highest
fundamental frequency, using the procedures set forth in the FCC KDB Publication No. 558074
“Guidance on Measurements for Digital Transmission Systems (47 CFR 15.247)”. Each emission found
to be in a restricted band as defined by section 15.205, was compared to the radiated emission limits as
defined in section 15.209.

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 measurements were made with RBW and VBW of 1
MHz. The EUT could not be placed in to a continuous transmit mode of operation there average
measurements could not be made. Peak measurements were compared to the average limits.

7.6.3.2 Test Results
Radiated spurious emissions found in the band of 30MHz to 10GHz are reported in Table 7.6.3.2-1.

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
Corrected Level: 49.91 - 0.18 = 49.73dBuV/m
Margin: 74dBuV/m – 49.73dBuV/m = 24.27dB

Example Calculation: Average
Corrected Level: 49.91 - 0.18 -0= 49.73dBuV
Margin: 54dBuV – 49.73dBuV = 4.27dB
