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 ANT-2.45-CHP-x is a ¼ wave omni-directional a 0.5dBi gain antenna chip.

7.2 Power Line Conducted Emissions
The Fluke-5 Bluetooth FHSS module receives its power from the robot host battery. No Power Line
Conducted Tests were performed.

7.3 Radiated Emissions - Unintentional Radiation

7.3.1 Test Methodology
Radiated emissions tests were performed over the frequency range of 30MHz to 12.5GHz.
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 from 30 - 1000MHz. For
measurement above 1000MHz both peak and average measurements were taken. Peak measurements
were taken with the RBW and VBW set 1MHz. Average measurements are taken with the RBW and
VBW set to 1MHz and 10 Hz respectively.

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 RF output port of the EUT was
directly connected to the input of the spectrum analyzer. 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 Channel Dwell Time

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 10 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 2.9 ms. Bluetooth uses 3 different packet types for data
transmission. The worst case dwell time will occur with the longest packet type, DH5. A DH5 packet
occupies 5 time slots (each 625 usecs) to transmit and then 1 time slot in receive mode. Bluetooth uses
79 different channels, thus it hops approximately 267 times a second. Thus, the same channel is visited
3.38 times a second, and over 31.6 seconds (0.4ms * 79 channels) it is visited 107 times. The TX time on
one channel for the largest packet, the DH5 packet, was measured to be 2.9 milliseconds.

Therefore the dwell time for a 31.6 second window is 107 * 2.9 = 310.3 milliseconds

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 approximately 884kHz. Results are shown below in
Table 7.5.4-1 and Figures 7.5.4-1 through 7.5.4-3.

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 low and high channels of operation to determine band-edge compliance.
All antenna types were evaluated. Because the upper band-edge coincides with a restricted band, band-
edge compliance for the upper band-edge was determined using the radiated mark-delta method as
outlined in FCC DA 00-705. The radiated field strength of the fundamental emission was first determined
and then the mark-delta method was used to determine the field strength of the band-edge emissions.

The lower band-edge compliance was determined using the marker-delta method in which the radio
frequency power that is 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.

For average measurements the duty cycle correction detailed in section 7.6.3.2 was applied.

7.6.1.2 Test Results
Band-edge compliance is displayed in Table 7.6.1.2-1 and Figures 7.6.1.2-1 – 7.6.1.2-2.

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 26GHz, 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 7.6.2.2-6.

7.6.3 Radiated Spurious Emissions – Intentional Radiation

7.6.3.1 Test Methodology
Radiated emissions tests were made over the frequency range of 30MHz to 25GHz, 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, measurements were made using an RBW of 1 MHz and a
VBW of 3 MHz.

7.6.3.2 Duty Cycle Correction
For average radiated measurements in restricted bands, the measured peak level was reduced by a
factor 30.75dB to account for the duty cycle of the EUT. The EUT transmits for 2.9ms on a channel and
does not return to the same channel for over 229 ms. Therefore the duty cycle is 2.9%. The duty cycle
correction factor is determined using the formula: 20log (0.029) = - 30.75dB.

7.6.3.3 Test Results
Radiated spurious emissions found in the band of 30MHz to 25GHz are reported in Table 7.6.3-1.

7.6.3.4 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:
Corrected Level: 57.96 + 5.04 = 63.00dBuV
Margin: 74dBuV – 63.00dBuV = 11.00dB

AVERAGE:
Corrected Level: 57.96 + 5.04 - 30.75 = 32.25dBuV
Margin: 54dBuV – 32.25dBuV = 21.75dB

8.0 CONCLUSION
In the opinion of ACS, Inc. the Fluke-5, provided by the Georgia Institute of Technology meets the
requirements of FCC Part 15 subpart C.
