Power Line Conducted Emissions 10.1. Block Diagram of Test Setup 10.2. Limit Maximum RF Line Voltage Frequency Quasi-Peak Level dB(μV) Average Level dB(μV) 150kHz ~ 500kHz 66 ~ 56* 56 ~ 46* 500kHz ~ 5MHz 56 46 5MHz ~ 30MHz 60 50 Notes: 1. * Decreasing linearly with logarithm of frequency. 2. The lower limit shall apply at the transition frequencies. 10.3. Test Procedure (1) The EUT was placed on a non-metallic table, 80cm above the ground plane. (2) Setup the EUT and simulator as shown in 10.1 (3) The EUT Power connected to the power mains through a power adapter and a line impedance stabilization network (L.I.S.N1). The other peripheral devices power cord connected to the power mains through a line impedance stabilization network (L.I.S.N2), this provided a 50-ohm coupling impedance for the EUT (Please refer to the block diagram of the test setup and photographs). Both sides of power line were checked for maximum conducted interference. In order to find the maximum emission, the relative positions of equipments and all of the interface cables were changed according to ANSI C63.4 2003 on conducted Emission test. (4) The bandwidth of test receiver is set at 10KHz. (5) The frequency range from 150 KHz to 30MHz is checked. 10.4. Test Result PASS.

Antenna Requirements Standard requirement: FCC Part15 C Section 15.203 /247(c) 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, 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. 15.247(c) (1)(i) requirement: (i) Systems operating in the 2400-2483.5 MHz band that is used exclusively for fixed. Point-to-point operations may employ transmitting antennas with directional gain greater than 6dBi provided the maximum conducted output power of the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna exceeds 6dBi. E.U.T Antenna: The antenna is PCB antenna, which permanently attached, and the best case gain of the antenna is 0 dBi. BT Antenna
