AC Power Conducted Emission TEST CONFIGURATION 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 C63.10-2013. 2 Support equipment, if needed, was placed as per ANSI C63.10-2013 3 All I/O cables were positioned to simulate typical actual usage as per ANSI C63.10-2013 4 The EUT received DC5V power, the 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. 8 During the above scans, the emissions were maximized by cable manipulation. AC Power Conducted Emission Limit For unintentional device, according to RSS Gen 8.8 and 15.207(a) Line Conducted Emission Limits is as following:

Frequency range (MHz) 0.15-0.5 0.5-5 5-30 Limit (dBuV) Quasi-peak 66 to 56*

56 60 Average 56 to 46*

The EUT was placed on a turn table which is 0.8m above ground plane when testing frequency range 9 KHz 1GHz;the EUT was placed on a turn table which is 1.5m above ground plane when testing frequency range 1GHz 25GHz. 2. Maximum procedure was performed by raising the receiving antenna from 1m to 4m and rotating the turn table from 0 to 360 to acquire the highest emissions from EUT. 3. And also, each emission was to be maximized by changing the polarization of receiving antenna both horizontal and vertical. 4. Repeat above procedures until all frequency measurements have been completed. 5. The EUT minimum operation frequency was 32.768KHz and maximum operation frequency was 2480MHz.so radiated emission test frequency band from 9KHz to 25GHz. 6. The distance between test antenna and EUT as following table states:

The basic equation with a sample calculation is as follows:

FS = RA + AF + CL - AG Where FS = Field Strength RA = Reading Amplitude AF = Antenna Factor CL = Cable Attenuation Factor (Cable Loss) AG = Amplifier Gain Transd=AF +CL-AG RADIATION LIMIT For intentional device, according to 15.209(a), the general requirement of field strength of radiated emission out of authorized band shall not exceed the following table at a 3 meters measurement distance. In addition, radiated emissions which fall in the restricted bands, as defined in 15.205(a), must also comply with the radiated emission limits specified in 15.209(a) Except when the requirements applicable to a given device state otherwise, emissions from licenceexempt transmitters shall comply with the field strength limits shown in table below. Additionally, the level of any transmitter emission shall not exceed the level of the transmitters fundamental emission Unwanted emissions that fall into restricted bands shall comply with the limits specified in RSS-Gen; and Unwanted emissions that do not fall within the restricted frequency bands shall comply either with the limits specified in the applicable RSS or with those specified in this RSS-Gen.

[Where F is the frequency in MHz, the formulas for calculating the maximum permitted fundamental field strengths are as follows: for the band 260-470 MHz, V/m at 3 meters = (41.6667 x f)-7083.3333. The maximum permitted unwanted emission level is 20 dB below the maximum permitted fundamental level.]
