Introduction The measurement procedure described in American National Standard for Methods of Measurement of Radio-Nose Emissions From Low-Voltage Electrical and Electronic Equipment in the Range of 9kHz to 40GHz (ASNI C63.4- 1992) was used in determining radiated and conducted emissions emanating from DONGYANG Electronics Co., Ltd. RF Transmitter (Built in AV Junction Controller Model No.: VC-10T), FCC ID.: RCDVC10T These measurement tests were conducted at Gumi College EMC Center. The site address is 407, Bugok-Dong, Gumi-City, Gyeongsangbuk-Do, Korea` This test site is one of the highest point of Gumi 1 college at about 200 kilometers away from Seoul city and 40 kilometers away from Daege city. It is located in the valley surrounded by mountains in all directions where ambient radio signal conditions are quiet and a favorable area to measure the radio frequency interference on open field test site for the computing and ISM devices manufactures. The detailed description of the measurement facility was found to be in compliance with the requirements of §2.948 according to ANSI C63.4 on…
