The EUT is a tabletop system, a wooden table with a height of 0.8 meters is used and is placed on the ground plane as per ANSI C63.10-2013. 2 Support equipment, if needed, was placed as per ANSI C63.10-2013 3 All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10-2013 4 The EUT received power from adapter, the adapter received AC120V/60Hz and AC 240V/60Hz power through a Line Impedance Stabilization Network (LISN) which supplied power source and was grounded to the ground plane. 5 All support equipments received AC power from a second LISN, if any. 6 The EUT test program was started. Emissions were measured on each current carrying line of the EUT using a spectrum Analyzer / Receiver connected to the LISN powering the EUT.The LISN has two monitoring points: Line 1 (Hot Side) and Line 2 (Neutral Side). Two scans were taken: one with Line 1 connected to Analyzer / Receiver and Line 2 connected to a 50 ohm load; the second scan had Line 1 connected to a 50 ohm load and Line 2 connected to the Analyzer / Receiver. 7 Analyzer / Receiver scanned from 150 KHz to 30MHz for emissions in each of the test modes. 8 During the above scans, the emissions were maximized by cable manipulation. AC Power Conducted Emission Limit For intentional device, according to § 15.207(a) AC Power Conducted Emission Limits is as following Frequency range (MHz) Limit (dBuV) Quasi-peak Average 0.15-0.5 66 to 56* 56 to 46* 0.5-5 56 46 5-30 60 50 * Decreases with the logarithm of the frequency.

The EUT was placed on a turn table which is 0.8m above ground plane when testing frequency range 9 KHz 1GHz;the EUT was placed on a turn table which is 1.5m above ground plane when testing frequency range 1GHz 25GHz. 2. Maximum procedure was performed by raising the receiving antenna from 1m to 4m and rotating the turn table from 0° to 360° to acquire the highest emissions from EUT. 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 measurements have been completed. 5. Radiated emission test frequency band from 9KHz to 25GHz. 6. The distance between test antenna and EUT as following table states: Test Frequency range Test Antenna Type Test Distance 9KHz-30MHz Active Loop Antenna 3 30MHz-1GHz Ultra-Broadband Antenna 3 1GHz-18GHz Double Ridged Horn Antenna 3 18GHz-25GHz Horn Anternna 1 7. Setting test receiver/spectrum as following table states: Test Frequency range Test Receiver/Spectrum Setting Detector 9KHz-150KHz RBW=200Hz/VBW=3KHz,Sweep time=Auto QP 150KHz-30MHz RBW=9KHz/VBW=100KHz,Sweep time=Auto QP 30MHz-1GHz RBW=120KHz/VBW=1000KHz,Sweep time=Auto QP Peak Value: RBW=1MHz/VBW=3MHz, 1GHz-40GHz Sweep time=Auto Average Value: RBW=1MHz/VBW=10Hz, Peak Sweep time=Auto Field Strength Calculation The field strength is calculated by adding the Antenna Factor and Cable Factor and subtracting the Amplifier Gain and Duty Cycle Correction Factor(if any) from the measured reading. The basic equation with a sample calculation is as follows: FS = RA + AF + CL - AG Where FS = Field Strength RA = Reading Amplitude AF = Antenna Factor CL = Cable Attenuation Factor (Cable Loss) AG = Amplifier Gain Transd=AF +CL-AG RADIATION LIMIT For intentional device, according to § 15.209(a), the general requirement of field strength of radiated emission from intentional radiators at a distance of 3 meters shall not exceed the following table. According to § 15.247(d), in any 100kHz bandwidth outside the frequency band in which the EUT is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20dB below that in the100kHz bandwidth within the band that contains the highest level of desired power. The pre-test have done for the EUT in three axes and found the worst emission at position shown in test setup photos.

If the transmitter com-plies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in §15.209(a) is not required. Test Procedure Connect the transmitter output to spectrum analyzer using a low loss RF cable, and set the spectrum analyzer to RBW=100 kHz, VBW= 300 kHz, peak detector , and max hold. Measurements utilizing these setting are made of the in-band reference level, bandedge and out-of-band emissions.
