 3.6. Band edge and Spurious Emission (conducted)
LIMIT

FCC CFR Title 47 Part 15 Subpart C Section15.247 (d):
In any 100 kHz bandwidth outside the frequency band in which the spread spectrum 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.

TEST CONFIGURATION




TEST PROCEDURE
1.   Connect the antenna port(s) to the spectrum analyzer input.
2.   Establish a reference level by using the following procedure
     Center frequency=DTS channel center frequency
     The span = 1.5 times the DTS bandwidth.
     RBW = 100 kHz, VBW ≥ 3 x RBW
     Detector = peak, Sweep time = auto couple, Trace mode = max hold
     Allow trace to fully stabilize
     Use the peak marker function to determine the maximum PSD level

     Note: the channel found to contain the maximum PSD level can be used to establish the reference level.
3.   Emission level measurement
     Set the center frequency and span to encompass frequency range to be measured
     RBW = 100 kHz, VBW ≥ 3 x RBW
     Detector = peak, Sweep time = auto couple, Trace mode = max hold
     Allow trace to fully stabilize
     Use the peak marker function to determine the maximum amplitude level.
4.   Place the radio in continuous transmit mode, allow the trace to stabilize, view the transmitter waveform on
     the spectrum analyzer.
5.   Ensure that the amplitude of all unwanted emissions outside of the authorized frequency band excluding
     restricted frequency bands) are attenuated by at least the minimum requirements specified (at least 20 dB
     relative to the maximum in-band peak PSD level in 100 kHz). Report the three highest emissions relative to
     the limit.


TEST MODE:
Please refer to the clause 2.3.

               Note: All restriction bands have been tested, only the worst case is reported.


Test Configuration




Test Procedure

1.   The EUT was setup and tested according to ANSI C63.10:2013 requirements.
2.   The EUT is placed on a turn table which is 0.1 meter above ground. The turn table is rotated 360 degrees to
     determine the position of the maximum emission level.
3.   The EUT was positioned such that the distance from antenna to the EUT was 3 meters.
4.   The antenna is scanned from 1 meter to 4 meters to find out the maximum emission level. This is repeated
     for both horizontal and vertical polarization of the antenna. In order to find the maximum emission, all of the
     interface cables were manipulated according to ANSI C63.10:2013 on radiated measurement.
5.   The receiver set as follow:
     RBW=1MHz, VBW=3MHz PEAK detector for Peak value.
     RBW=1MHz, VBW=10Hz with Average detector for Average Value.

Test Mode
        Please refer to the clause 2.3.


Test Results
     Passed                               Not Applicable

Note:
1) Final level= Read level + Antenna Factor + Cable Loss - Preamp Factor

                                           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 0.1 meter above ground for below 1 GHz, and 0.1m 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 10th harmonic:
     RBW=1MHz, VBW=1MHz Peak detector for Peak value.
     RBW=1MHz, VBW=10Hz RMS detector for Average value.

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: The amplitude of spurious emissions which are attenuated by more than 20dB below the permissible
      value has no need to be reported.
Note:
1) Final Level = Read level + Antenna Factor + Cable Loss -Preamplifier Factor
2)   The emission levels of other frequencies are very lower than the limit and not show in test report.

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.
