CONDUCTED EMISSION TEST 3.1 Block Diagram of Test Setup 3.2 Conducted Power Line Emission Limit According to FCC Part 15.207(a) * Decreasing linearly with the logarithm of the frequency For intentional device, according to §15.207Line Conducted Emission Limit is same as above table. 3.3 Test Procedure 1, The equipment was set up as per the test configuration to simulate typical actual usage per the user’s manual. The EUT is a tabletop system, a wooden table with a height of 0.8 meters is used and is placed on the ground plane as per ANSI C63.10. 2, Support equipment, if needed, was placed as per ANSI C63.10. 3, All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10. 4, If a EUT received DC power from the USB Port of Notebook PC, the PC’s adapter received AC120V/60Hz power through a Line Impedance Stabilization Network (LISN) which supplied power source and was grounded to the ground plane. 5, All support equipments received AC power from a second LISN, if any. 6, The EUT test program was started. Emissions were measured on each current carrying line of the EUT using a spectrum Analyzer / Receiver connected to the LISN powering the EUT. The LISN has two monitoring points: Line 1 (Hot Side) and Line 2 (Neutral Side). Two scans were taken: one with Line 1 connected to Analyzer / Receiver and Line 2 connected to a 50 ohm load; the second scan had Line 1 connected to a 50 ohm load and Line 2 connected to the Analyzer / Receiver. 7, Analyzer / Receiver scanned from 150 KHz to 30MHz for emissions in each of the test modes 3.4 Test Result PASS

Page 18 of 20 Report No.: HK1907231828-1E 6 ANTENNA REQUIREMENT 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. Refer to statement below for compliance. The manufacturer may design the unit so that the user can replace a broken antenna, but the use of a standard antenna jack or electrical connector is prohibited. Further, this requirement does not apply to intentional radiators that must be professionally installed.
