Frequency Separation Limit Frequency hopping systems shall have hopping channel carrier frequencies separated by minimum of 25 KHz or the 2/3*20dB bandwidth of the hopping channel, whichever is greater. Test Procedure The transmitter output was connected to the spectrum analyzer through an attenuator. The bandwidth of the fundamental frequency was measured by spectrum analyzer with 300 KHz RBW and 1000 KHz VBW.

Number of Hopping Frequency Limit Frequency hopping systems in the 2400–2483.5 MHz band shall use at least 15 channels. Test Procedure The transmitter output was connected to the spectrum analyzer through an attenuator. Set spectrum analyzer start 2400MHz to 2483.5MHz.

Time of Occupancy (Dwell Time) Limit The average time of occupancy on any channel shall not be greater than 0.4 seconds within a period of 0.4 seconds multiplied by the number of hopping channels employed. Test Procedure The transmitter output was connected to the spectrum analyzer through an attenuator. Set center frequency of spectrum analyzer=operating frequency with 1MHz RBW and 3MHz VBW, Span 0Hz.

Out-of-Band Emissions Limit In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated 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 con-ducted or a radiated measurement, pro-vided the transmitter demonstrates compliance with the peak conducted power limits. If the transmitter com-plies with the conducted power limits based on the use of RMS averaging over a time interval, as permitted under paragraph (b)(3) of this section, the attenuation required under this paragraph shall be 30 dB instead of 20 dB. Attenuation below the general limits specified in §15.209(a) is not required. Test Procedure Connect the transmitter output to spectrum analyzer using a low loss RF cable, and set the spectrum analyzer to RBW=100 kHz, VBW= 300 kHz, peak detector , and max hold. Measurements utilizing these setting are made of the in-band reference level, band edge and out-of-band emissions. Test Configuration EUT SPECTRUM ANALYZER Test Results Remark: The measurement frequency range is from 30MHz to the 10th harmonic of the fundamental frequency. The lowest, middle and highest channels are tested to verify the spurious emissions and bandage measurement data. We measured all conditions (DH1, DH3, DH5) and recorded worst case at DH5 and 2DH5 Test plot as follows: Page 35 of 45 Report No.: HK2608070804-E GFSK CH00 CH39 Page 36 of 45 Report No.: HK2608070804-E CH78 Page 37 of 45 Report No.: HK2608070804-E Left Band edge hoping off Right Band edge hoping off Left Band edge hoping on Right Band edge hoping on Page 38 of 45 Report No.: HK2608070804-E π/4DQPSK CH00 CH39 Page 39 of 45 Report No.: HK2608070804-E CH78 Page 40 of 45 Report No.: HK2608070804-E Left Band edge hoping off Right Band edge hoping off Left Band edge hoping on Right Band edge hoping on Page 41 of 45 Report No.: HK2608070804-E 3.9. Pseudorandom Frequency Hopping Sequence Test Applicable For 47 CFR Part 15C section 15.247 (a) (1): Frequency hopping systems shall have hopping channel carrier frequencies separated by a minimum of 25 kHz or the 20 dB bandwidth of the hop-ping channel, whichever is greater. Alternatively, frequency hopping systems operating in the 2400–2483.5 MHz band may have hopping channel carrier frequencies that are separated by 25 kHz or two-thirds of the 20 dB bandwidth of the hopping channel, whichever is greater, provided the systems operate with an output power no greater than 125 mW. The system shall hop to channel frequencies that are selected at the system hopping rate from a pseudo randomly ordered list of hopping frequencies. Each frequency must be used equally on the average by each transmitter. The system receivers shall have input bandwidths that match the hop-ping channel bandwidths of their corresponding transmitters and shall shift frequencies in synchronization with the transmitted signals. EUT Pseudorandom Frequency Hopping Sequence Requirement The pseudorandom frequency hopping sequence may be generated in a nice-stage shift register whose 5 th and 9 th stage outputs are added in a modulo-two addition stage.
