NOTE 3 The conversion factor between voltage limits and current limits is 20log =44 db. 3.4 Test Procedures The measuring process is according to VCCI Class B and laboratory internal procedure TKC For AC Mains Port In the conducted emission measurement, the EUT and all peripheral devices were set up on a non-metallic table which was 0.8 meters height above the ground plane, and 0.4 meters far away from the vertical plane. The EUT was powered by AC mains through Artificial Main Network (A.M.N), other peripheral devices were powered by AC mains through the second Line Impedance Stabilization Network (L.I.S.N). For the measurement, the A.M.N measuring port was terminated by a 50Ω measuring equipment and the second L.I.S.N measuring port was terminated by a 50Ω resistive load. All measurements were done on the phase and neutral line of the EUT s power cord. All cables or wires placement were verified to find maximum emission For Telecommunication Port The setup is the same as conduction besides this, connecting between AE and telecommunication port through ISN. Each phase of telecommunication wire is measured to evaluate the maximum conducted emission in accordance to VCCI Class B. The resolution bandwidth of measuring receiver was set at 9 khz.

16 Page 16 of 37 The frequency range (0.15 MHz ~ 30 MHz) was pre-scanned with a peak detector; the final measurement was measured with quasi-peak detector and average detector. (If the average limit is met when using a quasi-peak detector, the average detector is unnecessary). The emission level is calculated automatically by the test system which uses the following equation: Emission Level (dbμv) = Meter-Reading (dbμv) + A.M.N /I.S.N factor (db) + Cable Loss (db) (Cable Loss include pulse limiter loss) 3.5 Measurement Results PASSED (All the emissions not reported below are too low against the prescribed limits.)

NOTE 2 - Distance refers to the distance in meters between the measuring instrument antenna and the closed point of any part of the device or system Radiated Emission Limit (1GHz~6GHz, VCCI Class B) Frequency (GHz) Distance (m) Average Limit (dbμv/m) Peak Limit (dbμv/m) 1 ~ ~ NOTE - The lower limit applies at the transition frequency

26 Page 26 of Test Procedures The measuring process is according to VCCI Class B and laboratory internal procedure TKC In the radiated disturbance measurement, the EUT and all simulators were set up on a non-metallic turn table which was 0.8 meters above the ground plane. Measurement distance between EUT and receiving antennas was set at 10 meters at 30MHz~1000MHz and 3 meters at 1000MHz~6000MHz. The specified distance is the distance between the antennas and the closest periphery of EUT. During the radiated measurement, the EUT was rotated 360 and receiving antennas were moved from 1 ~ 4 meters for pre-test with peak detector. QP detector was used for final measurement to find maximum emission. Two receiving antennas were used for both horizontal and vertical polarization detection for 30MHz~1GHz, One receiving antennas was used for both horizontal and vertical polarization detection for 1GHz~6GHz (the absorbing material was added when testing of 1GHz~6GHz was done). All cables or wires placement were verified to find out the maximum emission. The bandwidth of measuring receiver (or spectrum analyzer) was set to: RBW (120 khz), VBW (300kHz) for QP detector below 1GHz RBW (1 MHz), VBW (1MHz) for Peak detector above 1GHz RBW (1 MHz), VBW (10 Hz) for Average detector above 1GHz Which is defined against CISPR section. The required frequency band (30 MHz ~ 6000 MHz) was pre-scanned with peak detector; all final measurements were measured with quasi-peak detector below 1GHz measured with average detector and peak detector above 1GHz. The emission level is calculated automatically by the test system which uses the following equation: 1.For MHz measurement: Emission Level (dbμv/m) = Meter-Reading (dbμv)+antenna Factor (db/m)+cable Loss (db) 2.For MHz measurement: Emission Level (dbμv/m) = Meter-Reading (dbμv)+antenna Factor (db/m)+cable Loss(dB) -Pre-amplifier factor (db) In chapter the standard CISPR requires to include the values of w in the test report: w: The dimension of the line tangent to the EUT formed by Ө 3dB at the measurement distance d. Equation (10) shall be used to calculate w for each actual antenna and measurement distance used. The values of w hall be included in the test report. This calculation may be based on the manufacturer-provided receive-antenna beamwidth specifications: w=2 d tan (0,5 Ө 3dB ) Frequency 3115 Horn GHz Ө 3dB d=3m ( ) w (M) The values of w. are greater than chapter of Table 2, the minimum dimension of w. (Wmin) requirements.
