Report No.: AGC08506190701FE01 Page 11 of 28 8.3. PROCEDURE OF LINE CONDUCTED EMISSION TEST (1) The equipment was set up as per the test configuration to simulate typical actual usage per the user’s manual. When 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 C63.4 (see Test Facility for the dimensions of the ground plane used). When the EUT is a floor-standing equipment, it is placed on the ground plane which has a 3-12 mm non-conductive covering to insulate the EUT from the ground plane. (2) Support equipment, if needed, was placed as per ANSI C63.4. (3) All I/O cables were positioned to simulate typical actual usage as per ANSI C63.4. (4) The EUT received DC 5V power from PC which received AC120V/60Hz power from a LISN. (5) 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. (6) Analyzer / Receiver scanned from 150 kHz to 30MHz for emissions in each of the test modes. (7) During the above scans, the emissions were maximized by cable manipulation. (8) A scan was taken on both power lines, Line 1 and Line 2, recording at least the six highest emissions. (9) Emission frequency and amplitude were recorded into a computer in which correction factors were used to calculate the emission level and compare reading to the applicable limit. If EUT emission level was less –2dB to the A.V. limit in Peak mode, then the emission signal was re-checked using Q.P and Average detector.

Report No.: AGC08506190701FE01 Page 15 of 28 9.3. PROCEDURE OF RADIATED EMISSION TEST (1) The equipment was set up as per the test configuration to simulate typical actual usage per the user’s manual. When the EUT is a tabletop system, a wooden turntable with a height of 0.8 meters is used which is placed on the ground plane as per ANSI C63.4 (see Test Facility for the dimensions of the ground plane used). When the EUT is floor-standing equipment, it is placed on the ground plane which has a 3-12 mm non-conductive covering to insulate the EUT from the ground plane. (2) Support equipment, if needed, was placed as per ANSI C63.4. (3) All I/O cables were positioned to simulate typical actual usage as per ANSI C63.4. (4) The EUT was connected to PC for charging. All support equipments received AC120V/60Hz power from socket under the turntable, if any. (5) The antenna was placed at 3 meter away from the EUT as stated in FCC Part 15. The antenna connected to the Analyzer via a cable and at times a pre-amplifier would be used. (6) The Analyzer / Receiver quickly scanned from 30MHz to 1000MHz. The EUT test program was started. Emissions were scanned and measured rotating the EUT to 360 degrees and positioning the antenna 1 to 4 meters above the ground plane, in both the vertical and the horizontal polarization, to maximize the emission reading level. (7) The test mode(s) were scanned during the test: (8) Recorded at least the six highest emissions. Emission frequency, amplitude, antenna position, polarization and turntable position were recorded into a computer in which correction factors were used to calculate the emission level and compare reading to the applicable limit and Q.P./Peak reading is presented.
