12 2.6 Measurement Results Explanation Example For all conducted test items: The offset level is set in the spectrum analyzer to compensate the RF cable loss between EUT conducted output port and spectrum analyzer. With the offset compensation, the spectrum analyzer reading level is exactly the EUT RF output level. Example: The spectrum analyzer offset is derived from RF cable loss. Offset = RF cable loss.

Limit of Radiated Band Edges and Spurious Emission In any khz bandwidth outside the intentional radiator frequency band, all harmonics/spurious must be at least 2 db below the highest emission level within the authorized band.

52 3.8.3 Test Procedures. The EUT was placed on a turntable with.8 meter for frequency below GHz and.5 meter for frequency above GHz 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 ntenna tower (from m to 4 m) and turntable (from degree to 36 degrees) to find the maximum reading. 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: () Span shall wide enough to fully capture the emission being measured; (2) Set RBW= khz for f < GHz, RBW=MHz for f>ghz ; VBW RBW; Sweep = auto; Detector function = peak; Trace = max hold for peak (3) For average measurement: use duty cycle correction factor method per 5.35(c). Duty cycle = On time/ milliseconds On time = N *L +N 2 *L N n- *LN n- +N n *L n Where N is number of type pulses, L is length of type pulses, etc. verage Emission Level = Peak Emission Level + 2*log(Duty cycle) 6. Corrected Reading: ntenna Factor + Cable Loss + Read Level - Preamp Factor = Level Note: The average levels were calculated from the peak level corrected with duty cycle correction factor (-24.79dB) derived from 2log (dwell time/ms). 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. Page Number : 52 of 64

55 3.8.6 Duty cycle correction factor for average measurement 3DH5 on time (One Pulse) Plot on Channel 39 3DH5 on time (Count Pulses) Plot on Channel 39 Note:. Worst case Duty cycle = on time/ milliseconds = 2 * 2.88 / = 5.76 % 2. Worst case Duty cycle correction factor = 2*log(Duty cycle) = db 3. 3DH5 has the highest duty cycle worst case and is reported. Sporton International (KunShan) INC. Page Number : 55 of 64

56 Duty Cycle Correction Factor Consideration for FH mode: Bluetooth normal hopping rate is 6Hz and reduced to 8Hz in FH mode; due to the reduced number of hopping frequencies, with the same packet configuration the dwell time in each channel frequency within msec period is longer in FH mode than normal mode. In FH mode, the minimum hopping frequencies are 2, to get the longest dwell time DH5 packet is observed; the period to have DH5 packet completing one hopping sequence is 2.88 ms x 2 channels = 57.6 ms There cannot be 2 complete hopping sequences within ms period, considering the random hopping behavior, maximum 2 hops can be possibly observed within the period. [ms / 57.6ms ] = 2 hops Thus, the maximum possible ON time: 2.88 ms x 2 = 5.76 ms Worst case Duty Cycle Correction factor, which is derived from the maximum possible ON time, 2 x log(5.76 ms/ms) = db Test Result of Radiated Spurious at Band Edges Please refer to ppendix Test Result of Radiated Spurious Emission (3MHz ~ th Harmonic) Please refer to ppendix.

Connect EUT to the power mains through a line impedance stabilization network (LISN). 3. ll the support units are connecting to the other LISN. 4. The LISN provides 5 ohm coupling impedance for the measuring instrument. 5. The FCC states that a 5 ohm, 5 microhenry LISN should be used. 6. Both sides of C line were checked for maximum conducted interference. 7. The frequency range from 5 khz to 3 MHz was searched. 8. Set the test-receiver system to Peak Detect Function and specified bandwidth (IF Bandwidth = 9kHz) with Maximum Hold Mode.
