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 users 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 PCs 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 9 of 20 Report No.: HK1907231828-1E Remark: We tested all mode, the worst(Wireless Output voltage DC9V ) case was recorded.

Occupied Bandwidth 4.1 Block Diagram of Test Setup 4.2 Rules and specifications CFR 47 Part 15.215(c) ANSI C63.10-2013 4.3 Test Procedure Intentional radiators operating under the alternative provisions to the general emission limits, as contained in 15.217 through 15.257 and in subpart E of this part, must be designed to ensure that 20dB bandwidth of the emission, or whatever bandwidth may otherwise be specified in the specific rule section under which the equip compliance with the 20dB attenuation specification may base on measurement at the intentional radiators antenna output terminal unless the intentional radiator uses a permanently attached antenna, in which case compliance shall be.deomonstrated by measuring the radiated emissions. 4.4 Test Result PASS Mode Tx Mode Freq

Measurements below 1000MHz are performed with a peak detector and compared to average limits, Measurements with an average detector are not required. Note:
For battery operated equipment, the equipment tests shall be performed using a new battery. 5.4 Test Result PASS For 9KHz-30MHz Remark: We tested 3 ANTENNAS and the voltage in 5VDC and 9VDC, the worst case ANTENNA 3 (5VDC) was recorded. Please refer to following diagram for individual Freq.

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.
