FCC RF Test Report Report No. : FR8D2801A 3.8.3 Test Procedures 1. The EUT was placed on a turntable with 0.8 meter for frequency below 1GHz and 1.5 meter for frequency above 1GHz respectively above ground. 2. The EUT was set 3 meters from the interference receiving antenna, which was mounted on the top of a variable height antenna tower. 3. 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. 4. Set to the maximum power setting and enable the EUT transmit continuously. 5. Use the following spectrum analyzer settings: (1) Span shall wide enough to fully capture the emission being measured; (2) Set RBW=100 kHz for f < 1 GHz, RBW=1MHz for f>1GHz ; VBW  RBW; 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) 6. Corrected Reading: Antenna Factor + Cable Loss + Read Level - Preamp Factor = Level 7. For testing below 1GHz, if the emission level of the EUT in peak mode was 3 dB lower than the limit specified, then peak values of EUT will be reported, otherwise, the emissions will be repeated one by one using the CISPR quasi-peak method and reported. 8. For testing above 1GHz, the emission level of the EUT in peak mode was 20dB lower than average limit (that means the emission level in average mode also complies with the limit in average mode), then peak values of EUT will be reported, otherwise, the emissions will be measured in average mode again and reported. Note: The average levels were calculated from the peak level corrected with duty cycle correction factor (-24.79dB) 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. Sporton International (Kunshan) Inc.

FCC RF Test Report Report No. : FR8D2801A 3.9 AC Conducted Emission Measurement 3.9.1 Limit of AC Conducted Emission For equipment that is designed to be connected to the public utility (AC) power line, the radio frequency voltage that is conducted back onto the AC power line on any frequency or frequencies within the band 150 kHz to 30 MHz shall not exceed the limits in the following table. Conducted limit (dBμV) Frequency of emission (MHz) Quasi-peak Average 0.15-0.5 66 to 56* 56 to 46* 0.5-5 56 46 5-30 60 50 *Decreases with the logarithm of the frequency. 3.9.2 Measuring Instruments The measuring equipment is listed in the section 4 of this test report. 3.9.3 Test Procedures 1. The EUT was placed 0.4 meter from the conducting wall of the shielding room was kept at least 80 centimeters from any other grounded conducting surface. 2. Connect EUT to the power mains through a line impedance stabilization network (LISN). 3. All the support units are connecting to the other LISN. 4. The LISN provides 50 ohm coupling impedance for the measuring instrument. 5. The FCC states that a 50 ohm, 50 microhenry LISN should be used. 6. Both sides of AC line were checked for maximum conducted interference. 7. The frequency range from 150 kHz to 30 MHz was searched. 8. Set the test-receiver system to Peak Detect Function and specified bandwidth (IF Bandwidth = 9kHz) with Maximum Hold Mode. Then measurement is also conducted by Average Detector and Quasi-Peak Detector Function respectively. Sporton International (Kunshan) Inc.

FCC RF Test Report Report No. : FR8D2801A 3.10 Antenna Requirements 3.10.1 Standard Applicable If directional gain of transmitting antennas is greater than 6dBi, the power shall be reduced by the same level in dB comparing to gain minus 6dBi. The use of a permanently attached antenna or of an antenna that uses a unique coupling to the intentional radiator shall be considered sufficient to comply with the rule. 3.10.2 Antenna Anti-Replacement Construction An embedded-in antenna design is used. 3.10.3 Antenna Gain The antenna peak gain of EUT is less than 6 dBi. Therefore, it is not necessary to reduce maximum peak output power limit. Sporton International (Kunshan) Inc.

Level(dBμV/m) = Antenna Factor(dB/m) + Cable Loss(dB) + Read Level(dBμV) - Preamp Factor(dB) 2. Over Limit(dB) = Level(dBμV/m) – Limit Line(dBμV/m) For Peak Limit @ 2390MHz: 1. Level(dBμV/m) = Antenna Factor(dB/m) + Cable Loss(dB) + Read Level(dBμV) - Preamp Factor(dB) = 32.22(dB/m) + 4.58(dB) + 54.51(dBμV) – 35.86 (dB) = 55.45 (dBμV/m) 2. Over Limit(dB) = Level(dBμV/m) – Limit Line(dBμV/m) = 55.45(dBμV/m) – 74(dBμV/m) = -18.55(dB) For Average Limit @ 2390MHz: 1. Level(dBμV/m) = Antenna Factor(dB/m) + Cable Loss(dB) + Read Level(dBμV) - Preamp Factor(dB) = 32.22(dB/m) + 4.58(dB) + 42.6(dBμV) – 35.86 (dB) = 43.54 (dBμV/m) 2. Over Limit(dB) = Level(dBμV/m) – Limit Line(dBμV/m) = 43.54(dBμV/m) – 54(dBμV/m) = -10.46(dB) Both peak and average measured complies with the limit line, so test result is “PASS”.

FCC RF Test Report Report No. : FR8D2801A Appendix C. Duty Cycle Plots DH5 on time (One Pulse) Plot on Channel 39 DH5 on time (Count Pulses) Plot on Channel 39 Note: 1. Worst case Duty cycle = on time/100 milliseconds = 2 * 2.88 / 100 = 5.76 % 2. Worst case Duty cycle correction factor = 20*log(Duty cycle) = -24.79 dB 3. DH5 has the highest duty cycle worst case and is reported. Sporton International (Kunshan) Inc.
