4. Description of Tests

4.1 Conducted Emission Measurement
Conducted emissions measurements were made in accordance with section 11, "Measurement of Information Technology
Equipment" of ANSI C63.4-2003. The measurement were performed over the frequency range of 0.15MHz to 30MHz using a
50Ω/50uH LISN as the input transducer to a Spectrum Analyzer or a Field Intensity Meter. The measurements were made
with the detector set for "Peak" amplitude within an bandwidth of 10KHz or for "quasi-peak" within a bandwidth of 9KHz.



The line-conducted emission test is conducted inside a shielded anechoic chamber room with 1m x 1.5m x 0.8m wooden table
which is placed 40cm away from the vertical wall and 1.5m away from the side wall of the chamber room. Two LISNs are
bonded to bottom plane of the shielded room. The EUT is powered from the Com-power LISN and the support equipment is
powered from the another Com-power LISN. Power to the LISNs is filtered by a noise cut power line filters. All electrical
cables are shielded by braided tinned steel tubing with inner φ 1.2cm. If the EUT is a DC-powered device, power will be
derived from the source power supply it normally will be powered from and these supply lines will be connected to the
Com-power LISN. All interconnecting cables more than 1m were shortened by non-inductive bundling(serpentine fashion) to
a 1m length. Sufficient time for the EUT, support equipment, and test equipment was allowed in order for them to warm up to
their normal operating condition. The RF output of the LISN was connected to the PMM9000 Spectrum Analyzer to determine
the frequency producing the max. Emission from the EUT. The frequency producing the max. Level was reexamined using the
detector function set to the CISPR Quasi-Peak mode by manual, after scanned by automatic Peak mode from 0.15 to 30MHz.
The bandwidth of the Spectrum Analyzer was set to 9kHz. The EUT, support equipment, and interconnecting cables were
arranged and manipulated to maximize each emission. Each emission was maximized by switching power lines, varying the
mode of operation or resolution, clock or data exchange speed, if applicable, whichever determined the worst-case emission.
Each emission reported was calibrated using self-calibrating mode.

Photographs of the worst-case emission can be seen in photographs of conducted emission test setup.

4.2 Radiated Emission Measurement
Preliminary measurements were made at indoors 3 meter semi EMC Anechoic Chamber using broadband antennas, broadband
amplifier, and spectrum analyzer to determine the emission frequencies producing the maximum EME.

Appropriate precaution was taken to ensure that all emissions from the EUT were maximized and investigated. The system
configuration, mode of operation, turntable azimuth with respect to the antenna were noted for each frequency found. The
spectrum was scanned from 30 to 1000 MHz using bilog antenna and above 1000 MHz, linearly polarized double ridge horn
antennas were used. Above 1GHz, linearly polarized double ridge horn antennas were used. The measurements were
performed with three frequencies which were selected as bottom, middle and top frequency in the operating band. Emission
level from the EUT with various configurations was examined on the spectrum analyzer connected with the RF amplifier and
plotted graphically.



Final measurements were made outdoors open site at 3-meter test range using bilog antenna. The output from the antenna was
connected, via a pre-selector or a preamplifier, to the input of the EMI Measuring Receiver and Spectrum analyzer(for above 1
GHz). The detector function was set to the quasi-peak or peak mode as appropriate. The measurement bandwidth on the Field
strength receiver was set to at least 120 kHz (1MHz for measurement above 1 GHz), with all post-detector filtering no less
than 10 times the measurement bandwidth. Sufficient time for the EUT, support equipment, and test equipment was allowed in
order for them to warm up to their normal operating condition.



Each frequency found during preliminary measurement was examined and investigated as the same set up and configuration
which produced the maximum emission The EUT, support equipment and interconnecting cables were configured to the set-up
producing the maximum emission for the frequency and were placed on top of a 0.8-meter high non-metallic 1m x 1.5 meter
table. The turntable containing the system was rotated and the antenna height was varied 1 to 4 meters and stopped at the
azimuth or height producing the maximum emission.



Each emission was maximized by varying the mode of operating frequencies of the EUT. The system was tested in all the
three orthogonal planes and changing the polarity of the antenna. The worst case emissions are recorded in the data tables. If
necessary, the radiated emission measurement could be performed at a closer distance to ensure higher accuracy and the
results were extrapolated to the specified distance using an inverse linear distance extrapolation factor(20 dB/decade) as per
section 15.31(f).

Photographs of the worst-case emission test setup can be seen in Appendix 1.

5. Test Condition

5.1 Test Configuration
    The device was configured for testing in a typical fashion (as a customer would normally use it). During the tests, the
    EUT and the supported equipments were installed to meet FCC requirement and operated in a manner which tends to
    maximize its emission level in a typical application.


   Radiated Emission Test
   Preliminary radiated emission tests were performed using the procedure in ANSI C63.4/2003 Clause 8.3 to determine the
   worst operating condition. Final radiated emission tests were conducted at 3 meter open field test site.


5.2 EUT operation
   EUT was tested according to the following operation modes provided by the specifications given by the manufacturer, and
   reported the worst emissions.

    NOTES :
     1.    * H : Horizontal polarization , ** V : Vertical polarization
     2.    Emission Level = Reading + Antenna factor + Cable loss
     3.    Margin value = Limit - Emission Level
     4.    All other emissions not reported were more than 25dB below the permitted limit.
     5.    Measurement uncertainty estimated at ±3.45 dB.
           The measurement uncertainty is given with a confidence of 95 % with the coverage factor, k=2.

7.1 Sample Calculations




                              dBµV = 20 log 10 (µV/m)

                                    µV = 10( dBµV/20)




EX. 1.

                    @ 2.386 MHz Class B limit(Qusi-Peak) = 56.00 dBµV
                    Reading = 41.97 dBµV (calibrated level)
                    AMN factor + Cable Loss = 0.60 dB
                    Total = 42.57 dBµV/m
                    Margin = 42.57 – 56.00 = -13.43
                             13.43 dB ; below limit




EX. 2.

                    @ 480.18 MHz Class B limit = 46.00 dBµV/m
                    Reading = 20.35 dBµV(calibrated level)
                    Antenna factor + Cable Loss = 22.34 dB
                    Total = 42.69 dBµV/m
                    10(43.12/20) =    µV/m
                    Margin = 42.69 – 46.00 = -3.31 dB
                               3.31 dB ; below limit
