Test Procedure The EUT was placed on a desk 0.8 m height from the metal ground plane and 0.4 m from the conducting wall of the shielding room and it was kept at least 0.8 m from any other grounded conducting surface. The size of the table will nominally be 1.5 m x1.0 m. The rear of the arrangement shall be flush with the back of the supporting tabletop unless that would not be possible or typical of normal use. All units of equipment forming the system under test (includes the EUT as well as connected peripherals and associated equipment or devices) shall be arranged such that a nominal 0.1 m separation is achieved between the neighboring units. Connect EUT to the power mains through a line impedance stabilization network (LISN). Where the mains cable supplied by the manufacturer is longer than 1 m, the excess should be folded at the centre into a bundle no longer than 0.4 m, so that its length is shortened to 1 m. All the support units are connecting to the other LISN. The LISN provides 50 ohm coupling impedance for the measuring instrument. TRF NO. FCC Part 15C Page 11 of 27 Report No.: ES190617076W01 Ver.1.0 Both sides of AC line were checked for maximum conducted interference. The frequency range from 150 kHz to 30 MHz was sweep. Set the test-receiver system to quasi peak detect function and average detect function, and to measure the conducted emissions values. Test results were obtained from the following equation:
Emission Level (dBV) = LISN Factor (dB) + Cable Loss (dB) + Reading (dBV) Margin (dB) = Emission Level (dBV) - Limit (dBV) 5.4. Measuring Results PASS. TRF NO.

Maximum procedure was performed on the six highest emissions to ensure EUT compliance. 3. And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical. 4. Repeat above procedures until all frequency measured were complete. 5. Use the following receiver/spectrum analyzer settings:
Span = wide enough to fully capture the emission being measured RBW=200Hz for 9KHz to 150KHz, RBW=9kHz for 150KHz to 30MHz, RBW=120KHz for 30MHz to 1GHz VBW 3*RBW Sweep = auto Detector function = QP Trace = max hold 6.2. Test SET-UP (Block Diagram of Configuration)
