Page 7 of 12 SKT SKTOS-00137 FCC ID : NTHESL1225 5. EMISSION Test 5.1 Conducted Emissions Result: Pass The line-conducted facility is located inside a 2.0M x 3.6M x 7.2M shielded enclosure. The shielding effectiveness of the shielded room is in accordance with MIL-Std-285 or NSA 604-05. A 1m x 1.5m wooden table 40cm. high is placed 40cm. away from the vertical wall and 1.5m away from the side wall of the shielded room. Kyoritsu Model KNW-407 (10kHz-30MHz) 50ohm/50 uH Line-Impedance Stabilization Networks(LISNs) are bonded to the shielded room. The EUT is powered from the Kyoritsu LISN and the support equipment is powered from the Kyoritsu LISN. Power to the LISNs are filtered by a high-current high-insertion loss Lindgren enclosures power line filters (100dB 14kHz-10GHz). The purpose of the filter is to attenuate am…
