3. Antenna Requirements

3.1. Standard Applicable
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.

And according to FCC 47 CFR Section 15.247 (b), if transmitting antennas of directional gain
greater than 6dBi are used, the power shall be reduced by the amount in dB that the directional gain
of the antenna exceeds 6dBi.

3.2. Antenna Construction and Directional Gain
Antenna type : The antenna is designed to be permanently on PCB, No

Consideration of replacement

Antenna Gain: 0 dBi

4. Test of Conducted Emission

4.1. Test Limit

Conducted Emissions were measured from 150 kHz to 30 MHz with a bandwidth of 9 KHz on the 115
VAC power and return leads of the EUT according to the methods defined in ANSI C63.4-1992
Section 3.1. The EUT was placed on a nonmetallic stand in a shielded room 0.8 meters above the
ground plane as shown in section 2.2. The interface cables and equipment positioning were varied
within limits of reasonable applications to determine the position produced maximum conducted
emissions.

Frequency Quasi Peak Average
(MHz) (dB µ V) (dB µ V)
0.15 – 0.5 66-56* 56-46*
0.5 – 5.0 56 46
5.0 – 30.0 60 50

4.2. Test Procedures

a. 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.
b. Connect EUT to the power mains through a line impedance stabilization network (LISN).
c. All the support units are connecting to the other LISN.
d. The LISN provides 50 ohm coupling impedance for the measuring instrument.
e. The FCC states that a 50 ohm, 50 micro-henry LISN should be used.
f. Both sides of AC line were checked for maximum conducted interference.
g. The frequency range from 150 kHz to 30 MHz was searched.
h. Set the test-receiver system to Peak Detect Function and Specified Bandwidth with Maximum
Hold Mode.
