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 antenna is an integrated single-band patch antenna which can not be altered without destroying the
device. This device is also professionally installed therefore meeting the requirements of CFR 47 Part
15.203. The antenna gain is 3dBi.

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

7.2.2 Test Results
Results of the test are shown below in and Tables 7.2-1 through 7.2-2.

7.3 Radiated Emissions - (Unintentional Radiation)

7.3.1 Test Methodology
Radiated emissions tests were performed over the frequency range of 30MHz to 10 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 were made with the
Spectrum Analyzer’s resolution bandwidth set to 120 KHz for measurements above 30MHz. Average
measurements are taken with the RBW and VBW were set to 1MHz and 10 Hz respectively for
measurements above 1000MHz.

7.3.2 Test Results
Results represent the worst case data from all models and operating voltages. Results of the test are
given in Tables 7.3-1 and 7.3-2 below:

7.4 Peak Output Power

7.4.1 Test Methodology (Conducted Method)
The 20dB bandwidth of the EUT was within the resolution bandwidth of spectrum analyzer, therefore the
power measurement was made using the spectrum analyzer method. The resolution and video
bandwidth were set to > 20 dB bandwidth of the emission measured. The device employs >50 channels
therefore the power is limited to 1 Watt.

7.5.3.1 Test Methodology
The emission measured centered on the analyzer and the span set to 0 Hz. The RBW was set to 1 MHz
and the VBW to 3 MHz. Sweep time was set to 200 ms to capture the burst duration of the emission.
The marker –delta function of the analyzer was employed to measure the burst duration.

7.5.3.2 Test Results
The duration of the RF transmission is 123 ms. There is a minimum 7.8 second period before the device
transmits on the same channel. Therefore the average time of occupancy on any channel in a 20 second
period is 369ms.

7.5.4 20dB Bandwidth

7.5.4.1 Test Methodology
The spectrum analyzer span was set to 2 to 3 times the estimated 20 dB bandwidth of the emission. The
RBW was to ≥ 1% of the estimated 20 dB bandwidth. 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 span and RBW were examined and re-adjusted if necessary to meet the requirements of 2 to 3 times
the 20 bandwidth for the span and ≥ 1% of the 20 dB bandwidth for the RBW.

7.5.4.2 Test Results
The maximum 20dB bandwidth was found to be a maximum of 148.2kHz. Results are shown below in

7.6 Band-Edge Compliance and Spurious Emissions

7.6.1 Band-Edge Compliance of RF Conducted Emissions

7.6.1.1 Test Methodology
The EUT was investigated at the lowest and highest channel available to determine band-edge
compliance. For each measurement the spectrum analyzer’s RBW was set to 100 kHz, which is ≥ 1% of
the span, and the VBW was set to 300kHz. The hopping function was enabled.

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 Figures 7.6.1-1 and 7.6.2-2

7.6.2 RF Conducted Spurious Emissions

7.6.2.1 Test Methodology
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.

7.6.2.1 Test Results
All emissions found were greater than 20dB down from the fundamental carrier. The RF conducted
spurious emissions were measured in the band of 30MHz to 10GHz. Results are shown below in Figures
7.6.2-1 through 7.6.2-6.

7.6.3 Radiated Spurious Emissions (Transmitter)

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.

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, average measurements were made using an RBW of 1
MHz and a VBW of 10 Hz and peak measurements were made with RBW of 1 MHz and a VBW of 1
MHz.

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

This device contains two transmitters, as described in section 1.0. These transmitters can not operate
simultaneously therefore inter-modulation products where not evaluated.

7.6.3.2 Test Results
Radiated spurious emissions found in the band of 30MHz to 10GHz are reported in Tables 7.6.3-1 and
7.6.3-2. 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.
