   5.6. Conducted Spurious Emissions and Band Edges Test

   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)).

   5.6.2. Measuring Instruments and Setting

     Please refer to equipment list in this report. The following table is the setting of the spectrum analyzer.

  5.7. AC Power Line Conducted Emissions

   5.7.1 Standard Applicable

    According to §15.207 (a): For an intentional radiator which 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 250 microvolts (The limit
    decreases linearly with the logarithm of the frequency in the range 0.15 MHz to 0.50 MHz). The limits at
    specific frequency range are listed as follows:

SHENZHEN LCS COMPLIANCE TESTING LABORATORY LTD.                         FCC ID: 2AC5R-SC-904BTK          Report No.:LCS190812007AEB

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 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.
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.

Remark:
1). Test results including cable loss;
2). “---“means that the fundamental frequency not for 15.209 limits requirement;
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=330Hz/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 highest gain of
the antenna within the operating band nearest in frequency to the restricted band emission being measured

  5.9. Antenna Requirements

   5.9.1 Standard Applicable

    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 provisions 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 intentional radiator is reduced by 1 dB
    for every 3 dB that the directional gain of the antenna exceeds 6dBi.

   5.9.2 Antenna Connected Construction
   5.9.2.1. Standard Applicable

    According to § 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.

   5.9.2.2. Antenna Connector Construction

    The gains of antenna used for transmitting is 0.8 dBi, and the antenna is a Multilayer Chip antenna
    connect to PCB board and no consideration of replacement. Please see EUT photo for details.

   5.9.2.3. Results: Compliance.

    Measurement

    The antenna gain of the complete system is calculated by the difference of radiated power in EIRP and
    the conducted power of the module.
    Conducted power refers ANSI C63.10:2013 Output power test procedure for DTS devices.
    Radiated power refers to ANSI C63.10:2013 Radiated emissions tests.
