POWER LINE CONDUCTED EMISSION MEASUREMENT 5.1. Block Diagram of Test Setup Metal ground plane Test receiver EUT LISN 80cm Metal ground plane AE 80cm 50 LISN LISN: Line Impedance Stabilization Network AE: Associated equipment EUT: Equipment under test 5.2. Limits FCC Part 15.207 Frequency (MHz) 0.15 ~ 0.50 0.50 ~ 5.00 5.00 ~ 30.00 Limit (dBV) Quasi-peak Level Average Level 66.0 ~ 56.0 * 56.0 ~ 46.0 * 56.0 46.0 60.0 50.0 NOTE1-The lower limit shall apply at the transition frequencies. NOTE2-The limit decreases linearly with the logarithm of the frequency in the range 0.15MHz to 0.50MHz. 5.3. 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.

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.

RADIATED EMISSION TEST 6.1. Measurement Procedure 1. The EUT was placed on a turn table which is 0.8m above ground plane. 2. 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.

ANTENNA APPLICATION 7.1. Antenna Requirement Standard FCC CRF Part 15.203 Requirement An intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the provisions of this section. The manufacturer may design the unit so that a broken antenna can be replaced by the user, but the use of a standard antenna jack or electrical connector is prohibited. This requirement does not apply to carrier current devices or to devices operated under the provisions of §15.211, §15.213, §15.217, §15.219, or §15.221. Further, this requirement does not apply to intentional radiators that must be professionally installed, such as perimeter protection systems and some field disturbance sensors, or to other intentional radiators which, in accordance with §15.31(d), must be measured at the installation site. However, the installer shall be responsible for ensuring that the proper antenna is employed so that the limits in this part are not exceeded. For intentional device, according to FCC 47 CFR Section 15.203, an intentional radiator shall be designed to ensure that no antenna other than that furnished by the responsible party shall be used with the device. 7.2. Result PASS. The EUT has 1 antennas: an Inductive Loop Antenna, antenna has a gain of 0 dBi; Note: Antenna use a permanently attached antenna which is not replaceable. Not using a standard antenna jack or electrical connector for antenna replacement The antenna has to be professionally installed (please provide method of installation) which in accordance to section 15.203, please refer to the internal photos. ----------------The end---------------- Address:No.11,WuSongRoad, DongchengDistrict,Dongguan, GuangdongProvince,China523117 Tel: 86-769-22607797 Fax: 86-769-22607907 http://www.cpcteam.com
