Transmitting mode with modulation Test Procedure:
1. The testing follows the guidelines in Spurious Radiated Emissions of ANSI C63.10:2013 Measurement Guidelines. 2. For the radiated emission test below 1GHz:
The EUT was placed on a turntable with 0.8 meter above ground. The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a variable height antenna tower. 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. For the radiated emission test above 1GHz:
Place the measurement antenna on a turntable with 1.5 meter above ground, which is away from each area of the EUT determined to be a source of emissions at the specified measurement distance, while keeping the measurement antenna aimed at the source of emissions at each frequency of significant emissions, with polarization oriented for maximum response. The measurement antenna may have to be higher or lower than the EUT, depending on the radiation pattern of the emission Hotline: 400-6611-140 Tel: 86-755-27673339 Fax: 86-755-27673332 http://www.tct-lab.com Page 41 of 60 Report No.: TCT190703E026 and staying aimed at the emission source for receiving the maximum signal. The final measurement antenna elevation shall be that which maximizes the emissions. The measurement antenna elevation for maximum emissions shall be restricted to a range of heights of from 1 m to 4 m above the ground or reference ground plane. 3. Set to the maximum power setting and enable the EUT transmit continuously. 4. Use the following spectrum analyzer settings:
(1) Span shall wide enough to fully capture the emission being measured;
(2) Set RBW=120 kHz for f < 1 GHz, RBW=1MHz for f>1GHz ; VBWRBW;
Sweep = auto; Detector function = peak; Trace
= max hold for peak
(3) For average measurement: use duty cycle correction factor method per 15.35(c). Duty cycle = On time/100 milliseconds On time =N1*L1+N2*L2+...+Nn-1*LNn-1+Nn*Ln Where N1 is number of type 1 pulses, L1 is length of type 1 pulses, etc. Average Emission Level = Peak Emission Level + 20*log(Duty cycle) Corrected Reading: Antenna Factor + Cable Loss + Read Level - Preamp Factor = Level Test results:

Test Data Duty cycle correction factor for average measurement 2DH5 on time (One Pulse) Plot on Channel 39 2DH5 on time (Count Pulses) Plot on Channel 39 Note:
1. Worst case Duty cycle = on time/100 milliseconds = (2.982*27+2.336)/100=0.8285 2. Worst case Duty cycle correction factor = 20*log (Duty cycle) = -1.64dB 3. 2DH5 has the highest duty cycle worst case and is reported. 4. The average levels were calculated from the peak level corrected with duty cycle correction factor (-1.64dB) derived from 20log (dwell time/100ms). This correction is only for signals that hop with the fundamental signal, such as band-edge and harmonic. Other spurious signals that are independent of the hopping signal would not use this correction.

Note:
1. Emission Level=Peak Reading + Correction Factor; Correction Factor= Antenna Factor + Cable loss Pre-amplifier 2. Margin (dB) = Emission Level (Peak) (dBV/m)-Average limit (dBV/m) 3. The emission levels of other frequencies are very lower than the limit and not show in test report. 4. Measurements were conducted from 1 GHz to the 10th harmonic of highest fundamental frequency. 5. Data of measurement shown ---in the above table mean that the reading of emissions is attenuated more than 20 dB below the limits or the field strength is too small to be measured. 6. Measurements were conducted in all two modulation (GFSK, Pi/4DQPSK), and the worst case Mode (Pi/4DQPSK) was submitted only. 7.
