TEST PROCEDURE
1. The EUT was setup and tested according to ANSI C63.10:2013 for compliance to FCC 47CFR 15.247
requirements.
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.
th
(3) From 1 GHz to 10 harmonic:
RBW=1MHz, VBW=3MHz Peak detector for Peak value.
RBW=1MHz, VBW=3MHz RMS detector for Average value.

TEST MODE:
Please refer to the clause 3.3

TEST RESULTS

Passed Not Applicable

Note:
1) Above 1GHz Final Level =Receiver 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.

 9 kHz ~ 30 MHz
The EUT was pre-scanned the frequency band (9 kHz ~ 30 MHz), found the radiated level lower than the
limit, so don’t show on the report.

 30 MHz ~ 1000 MHz
Have pre-scan all modulation mode, found the BT-BLE mode CH39 which it was worst case, so only the
worst case’s data on the test report.

Remark:
1. Final Level =Receiver Read level + Antenna Factor + Cable Loss – Preamplifier Factor
2. The peak level is lower than average limit(54dBuV/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.
