                          NOTE1: The lower limit shall apply at the transition frequencies.
                          NOTE2: The limit decreases linearly with the logarithm of the frequency in the
                                 range 0.15MHz to 0.50MHz.


                    4.4.Configuration of EUT on Measurement
                          The equipments are installed on Power Line Conducted Emission Measurement
                          to meet the commission requirement and operating regulations in a manner,
                          which tends to maximize its emission characteristics in a normal application.


                    4.5.Operating Condition of EUT
                              4.5.1.Setup the EUT and simulator as shown as Section 4.1.

                              4.5.2.Turn on the power of all equipment.

                              4.5.3.Let the EUT work in test mode and measure it.


                    4.6.Measurement Uncertainty
                          All measurements involve certain levels of uncertainties, especially in field of
                          EMC. The factors contributing to uncertainties are spectrum analyzer, cable loss,
                          and LISN.

                          The Treatment of Uncertainty in EMC Measurements, the best estimate of the
                          uncertainty of any conducted emissions measurement at ATC is +2.23dB.


                    4.7.Test Procedure
                          The EUT is put on the plane 0.8m high above the ground by insulating support
                          and is connected to the power mains through a line impedance stabilization
                          network (L.I.S.N.). This provides a 50ohm coupling impedance for the EUT
                          system. Please refer the block diagram of the test setup and photographs. Both
                          sides of AC lines are checked to find out the maximum conducted emission. In
                          order to find the maximum emission levels, the relative positions of equipment
                          and all of the interface cables shall be changed according to ANSI C63.4: 2014
                          on Conducted Emission Measurement.
                          The bandwidth of test receiver (R & S ESCS30) is set at 9kHz.

                          The frequency range from 150kHz to 30MHz is checked.

                    5.4.Operating Condition of EUT
                              5.4.1.Setup the EUT and simulator as shown as Section 5.1.

                              5.4.2.Turn on the power of all equipment.

                              5.4.3.Let the EUT work in test mode and measure it.


                    5.5.Test Procedure
                          The EUT and its simulators are placed on a turntable, which is 0.8 meter high
                          above ground. The turntable can rotate 360 degrees to determine the position
                          of the maximum emission level. EUT is set 3.0 meters away from the receiving
                          antenna, which is mounted on an antenna tower. The antenna can be moved up
                          and down between 1.0 meter and 4 meters to find out the maximum emission
                          level. Broadband antenna (calibrated bilog antenna) is used as receiving
                          antenna. Both horizontal and vertical polarizations of the antenna are set on
                          measurement. In order to find the maximum emission levels, all of the interface
                          cables must be manipulated according to ANSI C63.4: 2014 on radiated
                          emission measurement.

                          The bandwidth of the EMI test receiver (R&S ESCS30) is set at 120kHz.

                          The frequency range from 9kHz to 12750MHz is checked.

                          Note: The EUT highest operating frequency provided by Manufacturer is
                          2438MHz, the radiated emission measurement shall be made up to 12.75GHz.

                         Frequency(MHz) = Emission frequency in MHz
                         Reading(dBv) = Uncorrected Analyzer/Receiver reading
                         Factor (dB/m)= Antenna factor + Cable Loss – Amplifier gain
                         Result(dBv/m) = Reading + Factor
                         Limit (dBv/m)= Limit stated in standard

                         Margin (dB) = Result(dBv/m) - Limit (dBv/m)

                         Calculation Formula:

                         Margin(dB) = Result (dBv/m)–Limit(dBv/m)
                         Result(dBv/m)= Reading(dBv)+ Factor(dB/m)

                         The “Margin” column of the following data tables indicates the degree of
                         compliance with the applicable limit. For example, a margin of -7dB means the
                         emission is 7dB below the limit.


                    5.7.Radiated Emission Noise Measurement Result

                          PASS.

                          The frequency range from 9kHz to 12750MHz is investigated.

                          The radiation emissions from 9kHz-30MHz is not reported, because the test
                          values lower than the limits of 20dB.

                          The spectral diagrams are attached as below.
