FCC EMI TEST REPORT Report No. : FC892505 3. Test Result 3.1. Test of AC Conducted Emission Measurement 3.1.1 Limits of AC Conducted Emission For equipment that is designed to be connected to the public utility (AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency or frequencies within the band 150 kHz to 30 MHz shall not exceed the limits in the following table. Frequency of emission Conducted limit (dBuV) (MHz) 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. 3.1.2 Measuring Instruments Refer a test equipment and calibration data table in this test report. 3.1.3 Test Procedure 1. The EUT was placed 0.4 meter from the conducting wall of the shielding room was kept at least 80 centimeters from any other grounded conducting surface. 2. Connect EUT to the power mains through a line impedance stabilization network (LISN). 3. All the support units are connecting to the other LISN. 4. The LISN provides 50 ohm coupling impedance for the measuring instrument. 5. The FCC states that a 50 ohm, 50 microhenry LISN should be used. 6. Both sides of AC line were checked for maximum conducted interference. 7. The frequency range from 150 kHz to 30 MHz was searched. 8. Set the test-receiver system to Peak Detect Function and specified bandwidth (IF Bandwidth = 9kHz) with Maximum Hold Mode. Then measurement is also conducted by Average Detector and Quasi-Peak Detector Function respectively.

FCC EMI TEST REPORT Report No. : FC892505 3.2. Test of Radiated Emission Measurement 3.2.1. Limit of Radiated Emission The emissions from an unintentional radiator shall not exceed the field strength levels specified in the following table: Frequency Field Strength Measurement Distance (MHz) (microvolts/meter) (meters) 30 – 88 100 3 88 – 216 150 3 216 - 960 200 3 Above 960 500 3 3.2.2. Measuring Instruments Refer a test equipment and calibration data table in this test report. 3.2.3. Test Procedures 1. The EUT was placed on a turntable with 0.8 meter above ground. 2. The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a variable height antenna tower. 3. The table was rotated 360 degrees to determine the position of the highest radiation. 4. The antenna height is adjusted between one to four meters above ground to find the maximum value of the field strength for both horizontal polarization and vertical polarization of the antenna. 5. For each suspected emission, the EUT was arranged to its worst case and then tune the antenna tower (from 1 m to 4 m) and turntable (from 0 degree to 360 degrees) to find the maximum reading. 6. Set the test-receiver system to Peak Detect Function and specified bandwidth with Maximum Hold Mode (RBW=120kHz/VBW=300kHz for frequency below 1GHz; RBW=1MHz VBW=3MHz (Peak), RBW=1MHz/VBW=10Hz (Average) for frequency above 1GHz). 7. If the emission level of the EUT in peak mode was 3 dB lower than the limit specified, peak values of EUT will be reported. Otherwise, the emission will be repeated by using the quasi-peak method and reported. 8. Emission level (dBµV/m) = 20 log Emission level (µV/m) 9.
