3.   CONDUCTED EMISSIONS TEST

 3.1 Conducted Power Line Emission Limit
 For unintentional device, according to § 15.107(a) Line Conducted Emission Limits is as following




 * Decreasing linearly with the logarithm of the frequency
   For intentional device, according to §15.207(a) Line Conducted Emission Limit is same as above table.

 3.2 Test Setup




 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

 Not applicable for device which is DC Power supply.

  (3)Radiated Emission Test-Up Frequency Above 1GHz




4.3 Test Procedure
 1. Below 1GHz measurement the EUT is placed on turntable which is 0.8m above ground plane.
    And above 1GHz measurement EUT was placed on low permittivity and low tangent turn table
    which is 1.5m above ground plane.
 2. The turntable shall be rotated for 360 degrees to determine the position of maximum emission level.
 3. EUT is set 3m away from the receiving antenna, which is varied from 1m to 4m to find out the highest
   emissions.
 4. Maximum procedure was performed on the six highest emissions to ensure EUT compliance.
 5. And also, each emission was to be maximized by changing the polarization of receiving antenna both
   horizontal and vertical.
 6. Repeat above procedures until the measurements for all frequencies are complete.
 7. The test frequency range from 9KHz to 25GHz per FCC PART 15.33(a).

 Note:
 For battery operated equipment, the equipment tests shall be performed using a new battery.

 limits in §15.209, whichever is the lesser attenuation.


 5.2 Test Procedure
 The band edge compliance of RF radiated emission should be measured by following the guidance
 in ANSI C63.10 with respect to maximizing the emission by rotating the EUT, measuring the emission
 while the EUT is situated in three orthogonal planes (if appropriate), adjusting the measurement antenna
 height and polarization etc. Set RBW to 100KHz and VBM to 300KHz to measure the peak field strength
 and set RBW to 1MHz and VBW to 10Hz to measure the average radiated field strength.The conducted
 RF band edge was measured by using a spectrum analyzer. Set span wide enough to capture
 the highest in-band emission and the emission at the band edge. Set RBW to 100 KHz and VBW to
 300 KHz, to measure the conducted peak band edge.
