6.7.1. Test Specification

  Test Requirement:               FCC Part15 C Section 15.247 (d)

  Test Method:                    KDB558074
                                  In any 100 kHz bandwidth outside of the authorized
                                  frequency band, the emissions which fall in the
                                  non-restricted bands shall be attenuated at least 20 dB /
                                  30dB relative to the maximum PSD level in 100 kHz by
  Limit:
                                  RF conducted measurement and radiated emissions
                                  which fall in the restricted bands, as defined in Section
                                  15.205(a), must also comply with the radiated emission
                                  limits specified in Section 15.209(a).


  Test Setup:


  Test Mode:                      Transmitting mode with modulation
                                  1. The testing follows FCC KDB Publication No. 558074
                                      D01 15.247 Meas Guidance v05 v05r01.
                                  2. The RF output of EUT was connected to the spectrum
                                      analyzer by RF cable and attenuator. The path loss
                                      was compensated to the results for each
                                      measurement.
                                  3. Set to the maximum power setting and enable the
                                      EUT transmit continuously.
                                  4. Set RBW = 100 kHz, VBW=300 kHz, Peak Detector.
                                      Unwanted Emissions measured in any 100 kHz
                                      bandwidth outside of the authorized frequency band
  Test Procedure:
                                      shall be attenuated by at least 20 dB relative to the
                                      maximum in-band peak PSD level in 100 kHz when
                                      maximum peak conducted output power procedure is
                                      used. If the transmitter complies with the conducted
                                      power limits based on the use of RMS averaging over
                                      a time interval, the attenuation required under this
                                      paragraph shall be 30 dB instead of 20 dB per
                                      15.247(d).
                                  5. Measure and record the results in the test report.
                                  6. The RF fundamental frequency should be excluded
                                      against the limit line in the operating frequency band.
  Test Result:                    PASS

 Note: 1. 802.11b/802.11g is SISO, transimitte signal from two antenna is completely uncorrelated.
         802.11n(H20)/802.11n(H40) is MIMO, transimitte signal from two antenna is correlated.
       2. The calibration interval of the above test instruments is 12 months and the calibrations are traceable to
       international system unit (SI).
