7 3. Procedure of measurement Page: 6 of Conducted emissions Configuration of measurement This measurement executed in shield-room and EUT was tested on 0.8m height wooden table located on the floor with 0.1m distance from the reference ground plane. EUT's rear part had a distance from VCP(Vertical Conducted Plane) with 0.4m length and LISN placed on the grounded plane with 1m distance from EUT's side part. Excess power cord and cables fixed in bundle style of 30~40cm length with non-inductive material, and power line was connected to power source through LISN to detect maximum EMI without external RFI from aux. instruments. Measuring equipments and EUT confirmed that warming-up was performed during enough time and calibration of antenna as well as calibration of measuring equipment also completed beforehand. This measurement was performed on condition of worst-case emission Detector function selection and bandwidth During conducted emission measurement, a radio noise meter that has a CISPR quasi-peak detector with 10 khz IF bandwidth of 6 db was utilized Frequency range to be scanned For conducted emissions measurement, frequency range of 150 khz to 30 MHz included, was investigated Line impedance stabilization network (LISN) A LISN with characteristics that conform to the requirements of ANSI C was used for the measurement of conducted power-line radio noise; (50 micro-henries / 50 ohms). Chassis and earth-points for grounding of the LISN were earth-grounded.

8 Page: 7 of Radiated Emissions Configuration of measurement Preliminary measurement was performed in 3 meter semi-anechoic chamber to detect correct EMI frequency. Final measurement was executed at 10 meters OATS(Open Area Test Site) using Quasi-peak detector and TRILOG antenna. EUT was placed on 0.8m height wooden table located on the reference ground plane. Excess power cord and other excess cables fixed in bundle style of 30~40cm length with non-inductive material to detect maximum EMI emission from EUT. The height of the measuring antenna is varied 1 to 4 meters and table was rotated a full revolution in order to obtain maximum electric field intensity. The measurement is made in both the vertical and horizontal polarization, and measurement is performed with a quasi-peak detector. The highest emissions between 1 GHz to 6 GHz were analyzed in details by operating the spectrum analyzer in peak and average mode to determine the precise amplitude of the emissions. At the highest amplitudes observed, the EUT is rotated in the horizontal plane while changing the antenna polarization in the vertical plane to maximize the reading. The interconnecting cables were arranged and moved to get the maximum measurement. Once the maximum reading is obtained, the antenna elevation and polarization will be varied between specified limits to maximize the readings. The highest internal source of an EUT is defined as the highest frequency generated or used within the EUT or on which the EUT operates or tunes. If the highest frequency of the internal sources of the EUT is less than 108 MHz, the measurement shall only be made up to 1 GHz. If the highest frequency of the internal sources of the EUT is between 108 MHz and 500 MHz, the measurement shall only be made up to 2 GHz. If the highest frequency of the internal sources of the EUT is between 500 MHz and 1 GHz, the measurement shall only be made up to 5 GHz. If the highest frequency of the internal sources of the EUT is above 1 GHz, the measurement shall be made up to 5 times the highest frequency or 6 GHz, whichever is less Detector function selection and bandwidth In radiated emissions measurement, a field strength meter that has a CISPR quasi-peak detector was used. The 6 db bandwidth of the detector of instrument is 120 khz over frequency range of 30 to 1000 MHz.

9 Page: 8 of Method of Calculations Unit of Conducted emission measurement Conducted Emission Test results for conducted emissions are reported in micro-volts Unit of Radiated emission measurement Test results of radiated emissions measurement are reported in micro-volts per meter at the specific distance. Using the unit of dbuv on the test instrument, the indication unit was converted to field strength unit of uv/m as following method; F (µv/m) = 10 {(R+CL+AF)/20} (µv/m) F: Field Strength in uv/m, R: Meter Reading Level in db(µv), CL: Cable Loss from antenna to meter in db, AF: Antenna Factor of receiving antenna in db(/m) Sample calculation (Radiated emission) Emission level is calculated as follows; Emission Level(dBµV/m) = Reading Level + Ant. Factor + Cable Loss Amp Gain Margin Level is calculated as follows; Margin(dBµV) = Limit Level Emission Level Example) Standard limit = 40 dbµv/m, Reading Level = 10 dbµv, Ant. Factor = 15 db, Cable Loss= 1 db Emission Level(dBµV/m) = = 26 (dbµv/m) Margin(dBµV) = = 14 (dbµv)

Pressure 1011 hpa 4.2 Measurement uncertainty All measurements, especially EUT's measurement includes uncertain level that can happen for the reason as following; Variation of antenna factor by changes of height,center,polarization,directivity. Uncertainty factor by change of measurement distance, site's imperfection. Radiated emissions measurements: + 4 db Power line conducted emission measurements: + 3 db The measurement uncertainty describes the overall uncertainty of the given measured value during the operation of the EUT in the above mentioned way. The measurement uncertainty was calculated in accordance with NAMAS NIS 81 : The treatment of uncertainty in EMC measurement. The measurement uncertainty was given with a confidence of 95%.
