Below 1000MHz Test Setup Above 1GHz Test Setup Test Procedure 1. The EUT was setup and tested according to ANSI C63.10:2013 2. The EUT is placed on a turn table which is 0.8 meter above ground for below 1 GHz, and 1.5 m for above 1 GHz. The turn table is rotated 360 degrees to determine the position of the maximum emission level. 3. The EUT was set 3 meters from the receiving antenna, which was mounted on the top of a variable height antenna tower. 4. For each suspected emission, the EUT was arranged to its worst case and then tune the Antenna tower (from 1 m to 4 m) and turntable (from 0 degree to 360 degrees) to find the maximum reading. A pre-amp and a high pass filter are used for the test in order to get better signal level to comply with the guidelines. 5. Set to the maximum power setting and enable the EUT transmit continuously. 6. Use the following spectrum analyzer settings (1) Span shall wide enough to fully capture the emission being measured; (2) Below 1 GHz: RBW=120 kHz, VBW=300 kHz, Sweep=auto, Detector function=peak, Trace=max hold; If the emission level of the EUT measured by the peak detector is 3 dB lower than the applicable limit, the peak emission level will be reported. Otherwise, the emission measurement will be repeated using the quasi-peak detector and reported. (3) From 1 GHz to 10 th harmonic: RBW=1MHz, VBW=1MHz Peak detector for Peak value. RBW=1MHz, VBW=10Hz RMS detector for Average value. Page 59 of 97 Report No.: KS2008S00857E KSIGN(Guangdong) Testing Co., Ltd. Test Mode Please refer to the clause 2.3. Test Result 9 KHz~30 MHz and 18GHz~25GHz From 9 KHz~30 MHz and 18GHz~25GHz: Conclusion: PASS Note: 1) Measurement = Reading level + Correct Factor Correct Factor=Antenna Factor + Cable Loss -Preamplifier Factor 2) The peak level is lower than average limit(54 dBuV/m), this data is the too weak instrument of signal is unable to test. 3) The emission levels of other frequencies are very lower than the limit and not show in test report. 4) The amplitude of spurious emissions which are attenuated by more than 20dB below the permissible value has no need to be reported. 5) Pre-scan 802.11b/g/n(HT20/HT40) modulation, and found the 802.11b modulation 2412MHz which it is worse case for 30MHz-1GHz , so only show the test data for worse case. 6) Pre-scan 802.11b/g/n(HT20/HT40) modulation, and found the 802.11b modulation which it is worse case for above 1GHz, so only show the test data for worse case. BELOW 30MHZ No emission found between lowest internal used/generated frequencies to 30MHz.
