   5.6.1. Standard Applicable

    According to §15.247 (d): 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. Attenuation below the general limits specified in Section 15.209(a) is not required. In
    addition, radiated emissions which fall in the restricted bands, as defined in Section 15.205(a), must also
    comply with the radiated emission limits specified in Section 15.209(a) (see Section 15.205(c)).

  5.8. Restrict-band band-edge measurements
   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 558074 D01 for Antenna-port conducted measurement. Antenna-port conducted
   measurements may also be used as an alternative to radiated measurements for demonstrating
   compliance in the restricted frequency bands. If conducted measurements are performed, then proper
   impedance matching must be ensured and an additional radiated test for cabinet/case spurious emissions
   is required.
   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 AV 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 comp lete.
   6). Measure the conducted output power (in dBm) using the detector specified by the appropriate
   regulatory agency (see 12.2.2, 12.2.3, and 12.2.4 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). Convert the resultant EIRP level to an equivalent electric field strength using the following relationship:

   E = EIRP – 20log D + 104.77=EIRP+95.23

   Where:
   E = electric field strength in dBμV/m,
   EIRP = equivalent isotropic radiated power in dBm

   D = specified measurement distance in meters.
   11). 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 f requency that is
   within 20 percent of the nearest band edge frequency, but in no case shall a value less than 2 dBi be used.
   12). Compare the resultant electric field strength level to the applicable regulatory limit.
   13). Perform radiated spurious emission test duress until all measured frequencies were complete.

    3). The average measurement was not performed when the peak measured data under the limit of
    average detection.
    4). Detector AV is setting spectrum/receiver. RBW=1MHz/VBW=10Hz/Sweep time=Auto/Detector=Peak.
    5). 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

    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.

    According to antenna requirement of §15.203.
    An intentional radiator shall be designed to ensure that no antenna other than that furnished by the
    responsible party shall be used with the device. 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 provisions of this Section. The manufacturer may design the unit so that a broken antenna can be
    re-placed by the user, but the use of a standard antenna jack or electrical connector is prohibited. This
    requirement does not apply to carrier current devices or to devices operated under the provisio ns of
    Sections 15.211, 15.213, 15.217, 15.219, or 15.221. Further, this requirement does not apply to
    intentional radiators that must be professionally installed, such as perimeter protection systems and some
    field disturbance sensors, or to other intentional radiators which, in accordance with Section 15.31(d),
    must be measured at the installation site. However, the installer shall be responsible for ensuring that the
    proper antenna is employed so that the limits in this Part are not exceeded.

    And according to §15.247(4)(1), system operating in the 2400-2483.5MHz bands that are used
    exclusively for fixed, point-to-point operations may employ transmitting antennas with directional gain
    greater than 6dBi provided the maximum peak output power of the intentio nal radiator is reduced by 1 dB
    for every 3 dB that the directional gain of the antenna exceeds 6dBi.
