System configuration and Equipment setup are shown on Section 6 and Section 10.

8.1.1.1 Table-Top Equipment
EUT is placed on the wooden table raised 0.8meter above the metal ground plane.

8.1.1.2 Interconnecting Cables
Excess part of the interconnecting cables longer than 1 meter are bundled in the
center. Cables that hang closer than 40 cm to the ground plane is folded back and
forth forming bundle 30 to 40 cm long, hanging approx, in the middle between
ground plane and table.

8.1.1.3 AC Power Cord
AC power cord for EUT is connected to one LISN which is placed on top of ground
plane. The LISN is placed in 80 cm from the nearest part of EUT chassis.
The excess power cable is bundled in the center, or shortened to appropriate length.
AC cables except from the EUT are connected second LISN.

8.1.2 Measuring Instruments

(Resolution bandwidth : 10 kHz) built in test receiver is used for final measurement.
The test receiver is complied with the specification of the CISPR publication 16.

8.1.2.3 LISN
The 50µH/50Ω LISN is used. The chassis of the LISN is bonded to the ground plane
by the copper blade.
The lead to be tested is selectable by switch, and the terminals which are not
connected to the EUT are terminated in 50Ω resistor termination.

Akzo Kashima Report No. AKL-199374 FCC ID : BBP7080A Page 13 of 25 pages

8.1.3 Test Procedure

8.1.3.1 Preliminary Measurement
EUT is tested on all operating conditions.
The spectrum analyzer is controlled by the computer program to sweep regulation
frequency, then spectrum chart are plotted out to detect the worst conditions in
operating mode and/or configuration for the final test.
All leads other than safety ground are tested.

8.1.3.2 Final Measurement
The EUT is operated in the worst condition where maximum emission is detected
by the preliminary test. The equipment and cables are arranged or manipulated
within the range of the test standard in the above condition.
The each spectrum to be tested are measured in quasi-peak using the test receiver.
When the value in the quasi-peak mode is higher than the limit in the standard, the
measurement in the average mode is done to compare to the value in the quasi-peak
mode. If the value in the quasi-peak mode exceeds the value in the average mode by
more than 6 dB, the value reducing 13 dB from the value in the quasi mode is used
to compare to the limit.

8.2.3 Test Procedure

8.2.3.1 Preliminary Measurement
EUT is tested on all operating conditions.
The spectrum analyzer is set max-hold mode and swept during turntable was
rotated 0 to 360 degree. Then spectrum chart are plotted out to detect the worst
conditions in configuration, operating mode, or ambient noise notation.

8.2.3.2 Final Measurement
The EUT operated in the condition where maximum emission is detected in the
preliminary test.
The turntable azimuth(EUT direction) and antenna height are adjusted the
position so that maximum field strength is obtained for each frequency spectrum to
be measured. The equipment and cables are arranged or manipulated within the
range of the test standard in the above condition.
When the uncertain result was obtained, the measurement is retried by using the
half wave dipole antenna instead of the broadband antenna.

9.3 Sample Calculations

9.3.1 Conducted Emission

Example @ 5.1980 MHz

Emission Level = Meter Reading 29.1 dBuV
+ Factor + 6.8 dB
= 35.9 dBuV

Margin = Limit 48.0 dBuV
- Emission Level - 35.9 dBuV
= 12.1 dB

Factor = LISN Factor + Cable Loss + Pad Loss

9.3.2 Radiated Emission

Example @ 801.86 MHz

Emission Level = Meter Reading 36.5 dBuV
+ Factor + 5.5 dB
= 42.0 dBuV/m

- Emission Level - 42.0 dBuV/m
= 4.0 dB

Factor = Antenna Factor + Cable Loss - Amplifier Gain + Pad Loss
– Distance Conversion Factor

SECTION 12
12. UNCERTAINTY OF MEASUREMENT

Uncertainty of measurement

The uncertainty of the measurements performed for this report lies:
Radiated emission at 3m
30 MHz – 1000 MHz ……………… +/- 3.6 dB
Above 1 GHz ………………………. +/- 3.9 dB

Conducted emission
9 kHz – 30 MHz …………………… +/- 1.8 dB

These figures indicate the uncertainty of the measurements when the same staff
performs the test with the same testing equipment and facility.
The uncertainty of the measurements when a different staff with different equipment
and facility are under study.

Please note that these uncertainty are not reflected to the compliance judgement of
the test results in this report.

SECTION 14
14. DESCRIPTION OF TEST LABORATORY

14.1 Outline of Akzo Kashima Limited, EMC Division

Akzo Kashima Ltd. was established in 1975 for manufacturing specialty chemicals.
The shares are owned by Akzo Nobel KK (70%), the country organization in Japan for
Akzo Novel nv., and TOSOH Corporation (30%), one of the leading petrochemical
manufacturers in Japan. Akzo Nobel, headquartered in the Netherlands, is one of the
world’s leading companies in selected areas of chemicals, coatings, healthcare products
and fibers with work force of approximately 70,000 people in over 50 countries.
In 1984, in order to respond to the growing testing demand, in particular, for FCC
filing, Akzo Kashima started EMI testing business, installing the first open air test site
in Kashima, Ibaraki prefecture. Further the business has been expanded by installing
additional testing facilities not only in Kashima but also in other areas such as
Shizuoka, Nagano, Kanagawa and Tochigi. As results, Akzo Kashima has now 16 open
air test sites and 4 anechoic chambers for EMI/EMC testing. As the largest EMC
testing laboratory in number of testing facilities and staffs, EMC Division has been
organized separately in the company and independently operated in conformity with
the requirements of ISO Guide 25 (EN 45000) for its competency as a testing
laboratory.
Akzo Kashima EMC Division is the first foreign private laboratory accredited by
NVLAP, National Voluntary Laboratory Accreditation Program-NIST, USA. The
division has been certified, authorized and/or filed as a competent testing laboratory by
various testing organizations/authorities as described below.
