   5.4.4 Test Results

   The Dwell Time=Burst Width*Total Hops. The detailed calculations are showed as follows:
   The duration for dwell time calculation: 0.4[s]*hopping number=0.4[s]*79[ch] =31.6[s*ch];
   The burst width [ms/hop/ch], which is directly measured, refers to the duration on one channel hop.
   The hops per second for all channels: The selected EUT Conf uses a slot type of 5-Tx&1-Rx and a
   hopping rate of 1600 [ch*hop/s] for all channels. So the final hopping rate for all channels is
   1600/6=266.67 [ch*hop/s]
   The hops per second on one channel: 266.67 [ch*hops/s]/79 [ch] =3.38 [hop/s];
   The total hops for all channels within the dwell time calculation duration: 3.38 [hop/s]*31.6[s*ch]=106.67
   [hop*ch];
   The dwell time for all channels hopping: 106.67 [hop*ch]*Burst Width [ms/hop/ch].


     PASS
     Please refer to Appendix A.5

Remark:
1. Test results including cable loss;
2. Measured at difference Packet Type for each mode and recorded worst case for each mode.

   5.8. Band-edge Measurements for Radiated Emissions

   5.8.1 Standard Applicable

   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 conducted or a radiated measurement,
   provided the transmitter demonstrates compliance with the peak conducted power limits. If the
   transmitter complies 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. In addition, radiated emissions which fall in the restricted bands, as defined in §15.205(a),
   must also comply with the radiated emission limits specified in §15.209(a) (see §15.205(c)).

   5.8.2. Test Setup Layout




   5.8.3. Measuring Instruments and Setting
   Please refer to equipment list in this report. The following table is the setting of Spectrum Analyzer.

   5.8.4. Test Procedures

   According to KDB 412172 section 1.1 Field Strength Approach (linear terms):
   eirp = pt x gt = (E x d)2/30
    Where:
    pt = transmitter output power in watts, 
    gt = numeric gain of the transmitting antenna (unitless), 
    E = electric field strength in V/m, 
    d = measurement distance in meters (m).
    erp = eirp/1.64 = (E x d)2/(30 x 1.64)
    Where all terms are as previously defined.

1. Check the calibration of the measuring instrument using either an internal calibrator or a known signal
   from an external generator.
2. Remove the antenna from the EUT and then connect to a low loss RF cable from the antenna port to an
   EMI test receiver, then turn on the EUT and make it operate in transmitting mode. Then set it to Low
   Channel and High Channel within its operating range, and make sure the instrument is operated in its
   linear range.
3. Set both RBW and VBW of spectrum analyzer to 100 kHz with a convenient frequency span including
   100kHz bandwidth from band edge, for Radiated emissions restricted band RBW=1MHz, VBW=3MHz for
   peak detector and RBW=1MHz, VBW=1/B for Peak detector.
4. Measure the highest amplitude appearing on spectral display and set it as a reference level. Plot the
   graph with marking the highest point and edge frequency.
5. Repeat above procedures until all measured frequencies were complete.
6. Measure the conducted output power (in dBm) using the detector specified by the appropriate regulatory
   agency for guidance regarding measurement procedures for determining quasi-peak, peak, and average
   conducted output power, respectively).

7. Add the maximum transmit antenna gain (in dBi) to the measured output power level to determine the
    EIRP level (see 12.2.5 for guidance on determining the applicable antenna gain)
8. Add the appropriate maximum ground reflection factor to the EIRP level (6 dB for frequencies ≤ 30 MHz,
    4.7 dB for frequencies between 30 MHz and 1000 MHz, inclusive and 0 dB for frequencies > 1000 MHz).
9. For devices with multiple antenna-ports, measure the power of each individual chain and sum the EIRP
    of all chains in linear terms (e.g., Watts, mW).
10. Compare the resultant electric field strength level to the applicable regulatory limit.
11. Perform radiated spurious emission test duress until all measured frequencies were complete.

   5.8.5. Test Results
     PASS
     Please refer to Appendix A.8

Remark:
1. Measured at difference Packet Type for each mode and recorded worst case for each mode.
2. Worst case data at DH5 for GFSK, 2DH5 for π/4DQPSK modulation type;
3. Measured at Hopping and Non-Hopping mode, recorded worst at Non-Hopping mode.
4. The other emission levels were very low against the limit.
5. The average measurement was not performed when the peak measured data under the limit of average
   detection.
6. Detector AV is setting spectrum/receiver. RBW=1MHz/VBW=330Hz/Sweep time=Auto/Detector=Peak;
7. Since the out-of-band characteristics of the EUT transmit antenna will often be unknown, the use of a
   conservative antenna gain value is necessary. Thus, when determining the EIRP based on the measured
   conducted power, the upper bound on antenna gain for a device with a single RF output shall be selected
   as the maximum in-band gain of the antenna across all operating bands, or 2 dBi, whichever is greater.
   However, for devices that operate in multiple frequency bands while using the same transmit antenna,
   the highest gain of the antenna within the operating band nearest in frequency to the restricted band
   emission being measured may be used in lieu of the overall highest gain when the emission is at a
   frequency that is within 20 percent of the nearest band edge frequency, but in no case shall a value less
   than 2 dBi be used.

   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.

   5.9.2 EUT Pseudorandom Frequency Hopping Sequence Requirement

  The pseudorandom frequency hopping sequence may be generated in a nice-stage shift register whose
  5th first stage. The sequence begins with the first one of 9 consecutive ones, for example: the shift
  register is initialized with nine ones.
● Number of shift register stages:9
● Length of pseudo-random sequence:29-1=511 bits
● Longest sequence of zeros:8(non-inverted signal)




   An example of pseudorandom frequency hopping sequence as follows:




    Each frequency used equally one the average by each transmitter.
   The system receiver have input bandwidths that match the hopping channel bandwidths of their
   corresponding transmitter and shift frequencies in synchronization with the transmitted signals.
