 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
  Pass
   Remark:
   1. All modes were tested at AC 120V and 240V, only the worst result of AC 120V was reported.

   reported as below:

   Remark:
   (1) Measuring frequencies from 1 GHz to the 25 GHz.
   (2) “F” denotes fundamental frequency; “H” denotes spurious frequency. “E” denotes band edge
   frequency.
   (3) * denotes emission frequency which appearing within the Restricted Bands specified in provision
   of 15.205, then the general radiated emission limits in 15.209 apply.
   (4) Data of measurement within this frequency range shown “--- ” in the table above means the
   reading of emissions are attenuated more than 20dB below the permissible limits or the field
   strength is too small to be measured.
   (5) The IF bandwidth of EMI Test Receiver between 30MHz to 1GHz was 120KHz, 1 MHz for
   measuring above 1 GHz, below 30MHz was 10KHz. The resolution bandwidth of test
   receiver/spectrum analyzer is 1MHz and video bandwidth is 3MHz for peak measurement with peak
   detector at frequency above 1GHz. The resolution bandwidth of test receiver/spectrum analyzer is
   1MHz and video bandwidth is 10Hz for Average measurement with peak
   detection at frequency above 1GHz.
   (6) When the test results of Peak Detected below the limits of Average Detected, the Average
   Detected is not need completed. For example: Top Channel at Fundamental 73.16dBuV/m(PK
   Value) <93.98(AV Limit), at harmonic 53.20 dBuV/m(PK Value) <54 dBuV/m(AV Limit), the Average
   Detected not need to completed.
   (7) All modes of operation were investigated and the worst-case emissions are reported.

5. BAND EDGE

   5.1 Limits
   FCC PART 15.249(d) Emissions radiated outside of the specified frequency bands, except for harmonics,
   shall be attenuated by at least 50 dB below the level of the fundamental or to the general radiated emission
   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.

   5.3 Test Result

      PASS

9.3 Limit
  In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated
  intentional radiator is operating, the radio frequency power that is produced by the intentional radiator shall
  be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the
  desired power, based on either an RF conducted or a radiated measurement, provided the transmitter
  demonstrates compliance with the peak conducted power limits. If the transmitter complies with the
  conducted power limits based on the use of RMS averaging over a time interval, as permitted under
  paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of
  20dB.

10. SPURIOUS RF CONDUCTED EMISSION

10.1 Test Limit

  1. Below -20dB of the highest emission level in operating band.
  2. Fall in the restricted bands listed in section 15.205. The maximum permitted average field strength is
  listed in section 15.209.
  3.For below 30MHz,For 9KHz-150kHz,150K-10MHz,We use the RBW 1KHz,10KHz, So the limit need to
    calculated by “10lg(BW1/BW2)“. for example For9KHz-150kHz,RBW 1KHz, The Limit= the highest
    emission level-20-10log(100/1)= the highest emission level-40.

10.2 Test Procedure
  The Spurious RF conducted emissions compliance of RF radiated emission should be measured by
   following the guidance in ANSI C63.10-2013, For 9KHz-150kHz, Set RBW=1kHz and VBW= 3KHz;
  For 150KHz-10MHz, Set RBW=10kHz and VBW= 30KHz:For 10MHz-25GHz ,Set RBW=100kHz and
  VBW= 300KHz in order to measure the peak field strength, and mwasure frequeny range from 9KHz
  to 25GHz.
