Page7 of 24 Report Number: SZ0801001-E May 12, 2008 7 7.1 7.1.1 TEST RESULTS LINE CONDUCTED MEASUREMENT PROCEDURE PRELIMINARY 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 EN55022 (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 EN55022. 3) All I/O cables were positioned to simulate typical actual usage as per EN55022. 4) The EUT received power from PC, and PC received AC230V/50Hz power through a Line Impedance Stabilization Network (LISN) which supplied power source and was grounded to the ground plane. 5) All support equipments received power from a second LISN supplying power of AC 230V/50Hz, 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 150kHz to 30MHz for emissions in each of the test modes. 8) During the above scans, the emissions were maximized by cable manipulation. 9) The following test mode(s) were scanned during the preliminary test: Preliminary Conducted Emission Test Frequency Range Investigated Mode of operation 150KHz TO 30 MHz Date Data Report No. Worst Mode Then, the EUT configuration and cable configuration of the above highest emission level were recorded for reference of final testing. Note: According to this case, this test item needs not to be carried out. SEC Engineering Service Co., Ltd. Page8 of 24 Report Number: SZ0801001-E May 12, 2008 7.1.2 FINAL LINE CONDUCTED EMISSION TEST 1) EUT and support equipment was set up on the test bench as per step 9 of the preliminary test. 2) A scan was taken on both power lines, Line 1 and Line 2, recording at least the six highest emissions. 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 an Average detector. 3) The test data of the worst case condition(s) was reported on the Summary Data page.

Page9 of 24 Report Number: SZ0801001-E May 12, 2008 7.2 RADIATED MEASUREMENT PROCEDURE 7.2.1 PRELIMINARY 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 EN 55022 (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 EN55022. 3) All I/O cables were positioned to simulate typical actual usage as per EN55022. 4) The EUT received DC power from PC, and PC received AC 230V/50Hz through the outlet socket under the turntable. All support equipments received AC 230V/50Hz power from socket under the turntable, if any. 5) The antenna was placed at 3 meter away from the EUT as stated in EN55022. 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 following test mode(s) were scanned during the preliminary test: Preliminary Radiated Emission Test Frequency Range Investigated 30 MHz TO 1000 MHz Mode of operation Date Data Report No. Working 01/07/2008 MSX8PRO _0(V,H) Worst Mode Then, the EUT and cable configuration, antenna position, polarization and turntable position of the above highest emission level were recorded for final testing. SEC Engineering Service Co., Ltd. Page10 of 24 Report Number: SZ0801001-E May 12, 2008 7.2.2 FINAL RADIATED EMISSION TEST 1) EUT and support equipment were set up on the turntable as per step 7 of the preliminary test. 2) The Analyzer / Receiver scanned from 30MHz to 1000MHz. Emissions were scanned and measured rotating the EUT to 360 degrees, varying cable placement 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. 3) 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. 4) The test data of the worst case condition(s) was reported on the Summary Data page.
