2.0          PRODUCT INFORMATION

2.1           Equipment Description
The Equipment Under Test (EUT) is the LG Portable Handset FCC ID: ZNFQ720PS. The test data contained in
this report pertains only to the emissions due to the EUT’s Bluetooth transmitter.
•      This Bluetooth module has been tested by a Bluetooth Qualification Lab, and we confirm the following:
            A) The hopping sequence is pseudorandom
            B) All channels are used equally on average
            C) The receiver input bandwidth equals the transmit bandwidth
            D) The receiver hops in sequence with the transmit signal
•      15.247(g): In accordance with the Bluetooth Industry Standard, the system is designed to comply with all of the
       regulations in Section 15.247 when the transmitter is presented with a continuous data (or information) system.
•      15.247(h): In accordance with the Bluetooth Industry Standard, the system does not coordinate its channels selection/
       hopping sequence with other frequency hopping systems for the express purpose of avoiding the simultaneous
       occupancy of individual hopping frequencies by multiple transmitters.
•      15.247(h): The EUT employs Adaptive Frequency Hopping (AFH) which identifies sources of interference namely devices
       operating in 802.11 WLAN and excludes them from the list of available channels. The process of re-mapping reduces the
       number of test channels from 79 channels to a minimum number of 20 channels.

3.2           Radiated Emissions
The radiated test facilities consisted of an indoor 3 meter semi-anechoic chamber used for final measurements
and exploratory measurements, when necessary. The measurement area is contained within the semi-anechoic
chamber which is shielded from any ambient interference. The test site inside the chamber is a 6m x 5.2m
elliptical, obstruction-free area in accordance with Figure 5.7 of Clause 5 in ANSI C63.4-2014. Absorbers are
arranged on the floor between the turn table and the antenna mast in such a way so as to maximize the reduction
of reflections for measurements above 1GHz. An 80cm tall test table made of Styrodur is placed on top of the turn
table. For measurements above 1GHz, an additional Styrodur pedestal is placed on top of the test table to bring
the total table height to 1.5m.

For all measurements, the spectrum was scanned through all EUT azimuths and from 1 to 4 meter receive
antenna height using a broadband antenna from 30MHz up to the upper frequency shown in 15.33 depending on
the highest frequency generated or used in the device or on which the device operates or tunes. For frequencies
above 1GHz, linearly polarized double ridge horn antennas were used. For frequencies below 30MHz, a
calibrated loop antenna was used. When exploratory measurements were necessary, they were performed at 1
meter test distance inside the semi-anechoic chamber using broadband antennas, broadband amplifiers, and
spectrum analyzers to determine the frequencies and modes producing the maximum emissions. Sufficient time
for the EUT, support equipment, and test equipment was allowed in order for them to warm up to their normal
operating condition. The test set-up was placed on top of the 1 x 1.5 meter table. The EUT, support equipment,
and interconnecting cables were arranged and manipulated to maximize each emission. Appropriate precaution
was taken to ensure that all emissions from the EUT were maximized and investigated. The system configuration,
mode of operation, turntable azimuth, and receive antenna height was noted for each frequency found.

Final measurements were made in the semi-anechoic chamber using calibrated, linearly polarized broadband and
horn antennas. The test setup was configured to the setup that produced the worst case emissions. The spectrum
analyzer was set to investigate all frequencies required for testing to compare the highest radiated disturbances
with respect to the specified limits. The turntable containing the EUT was rotated through 360 degrees and the
height of the receive antenna was varied 1 to 4 meters and stopped at the azimuth and height producing the
maximum emission. Each emission was maximized by changing the orientation of the EUT through three
orthogonal planes and changing the polarity of the receive antenna, whichever produced the worst-case
emissions.

All radiated measurements are performed in a chamber that meets the site requirements per ANSI C63.4-2014.
Additionally, radiated emissions below 30MHz are also validated on an Open Area Test Site to assert correlation
with the chamber measurements per the requirements of KDB 474788 D01.

3.3           Environmental Conditions
The temperature is controlled within range of 15oC to 35oC. The relative humidity is controlled within range of 10%
to 75%. The atmospheric pressure is monitored within the range 86-106kPa (860-1060mbar).

Excerpt from §15.203 of the FCC Rules/Regulations:
“An intentional radiator antenna shall be designed to ensure that no antenna other than that furnished by the
responsible party can 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 antennas of the EUT are permanently attached.

  •      There are no provisions for connection to an external antenna.


Conclusion:
The EUT complies with the requirement of §15.203.

7.2           Radiated Spurious Emission Measurements – Above 1GHz
§15.205 §15.209 §15.247 (d); RSS-Gen [8.9]

Test Overview and Limit

All out of band radiated spurious emissions are measured with a spectrum analyzer connected to a receive
antenna while the EUT is operating at maximum power and at the appropriate frequencies. Only the radiated
emissions of the configuration that produced the worst case emissions are reported in this section.

All out of band emissions appearing in a restricted band as specified in Section 15.205 of the Title 47 CFR
and Table 6 of RSS-Gen (8.10) must not exceed the limits shown in Table 7-2 per Section 15.209 and RSS-
Gen (8.9).

Test Notes

1. All emissions lying in restricted bands specified in §15.205 and Section 8.10 of RSS-Gen are below the limit
      shown in Table 7-2.
2. No significant radiated emissions were found in the 2310 - 2390MHz restricted band.
3. The antenna is manipulated through typical positions, polarity and length during the tests. The EUT is
      manipulated through three orthogonal planes.
4. This unit was tested with its standard battery.
5. The spectrum is measured from 9kHz to the 10th harmonic and the worst-case emissions are reported.
6. The duty cycle correction factor was not applied to noise floor measurements.
7. The wide spectrum spurious emissions plots shown on the following pages are used only for the purpose of
      emission identification. Any emissions found to be within 20dB of the limit are fully investigated and the results
      are shown in this section.
8. The "-" shown in the following RSE tables are used to denote a noise floor measurement.

Sample Calculation

       o     Field Strength Level [dBV/m] = Analyzer Level [dBm] + 107 + AFCL [dB/m] + Duty Cycle Correction [dB]
       o     AFCL [dB/m] = Antenna Factor [dB/m] + Cable Loss [dB]
       o     Margin [dB] = Field Strength Level [dBV/m] – Limit [dBV/m]

Duty Cycle Correction Factor Calculation
       o     Channel hop rate = 800 hops/second (AFH Mode)
       o      Adjusted channel hop rate for DH5 mode = 133.33 hops/second
       o      Time per channel hop = 1 / 133.33 hops/second = 7.50 ms
       o      Time to cycle through all channels = 7.50 x 20 channels = 150 ms
       o      Number of times transmitter hits on one channel = 100 ms / 150 ms = 1 time(s)
       o      Worst case dwell time = 7.5 ms
       o      Duty cycle correction factor = 20log10(7.5ms/100ms) = -22.5 dB

7.3           Radiated Restricted Band Edge Measurements
§15.205 §15.209 §15.247 (d); RSS-Gen [8.9]

The radiated restricted band edge measurements are measured with an EMI test receiver connected to the
receive antenna while the EUT is transmitting. Two different amplitude offsets were used depending on whether
peak or average measurements were measured. The average measurements use a duty cycle correction factor
(DCCF).

The amplitude offset shown in the following plots for average measurements was calculated using the formula:

Offset (dB) = (Antenna Factor + Cable Loss + Attenuator) – Preamplifier Gain + DCCF

Worst Case Mode:                                 Bluetooth

7.4           Radiated Spurious Emissions Measurements – Below 1GHz
§15.209; RSS-Gen [8.9]

Test Overview and Limit

All out of band radiated spurious emissions are measured with a spectrum analyzer connected to a receive
antenna while the EUT is operating at its maximum duty cycle, at maximum power, and at the appropriate
frequencies. All data rates and modes were investigated for radiated spurious emissions. Only the radiated
emissions of the configuration that produced the worst case emissions are reported in this section.

All out of band emissions appearing in a restricted band as specified in Section 15.205 of the Title 47 CFR
and Table 6 of RSS-Gen (8.10) must not exceed the limits shown in Table 7-7 per Section 15.209 and RSS-
Gen (8.9).

Test Notes

      1. All emissions lying in restricted bands specified in §15.205 and RSS-Gen (8.10) are below the limit shown
             in Table 7-7.
      2. The broadband receive antenna is manipulated through vertical and horizontal polarizations during the
             tests. The EUT is manipulated through three orthogonal planes.
      3. This unit was tested with its standard battery.
      4. The spectrum is investigated using a peak detector and final measurements are recorded using CISPR
             quasi peak detector. The worst-case emissions are reported however emissions whose levels were not
             within 20dB of the respective limits were not reported.
      5. Emissions were measured at a 3 meter test distance.
      6. Emissions are investigated while operating on the center channel of the mode, band, and modulation that
             produced the worst case results during the transmitter spurious emissions testing.
      7. No spurious emissions were detected within 20dB of the limit below 30MHz.
      8. The results recorded using the broadband antenna is known to correlate with the results obtained by
             using a tuned dipole with an acceptable degree of accuracy. The VSWR for the measurement antenna
             was found to be less than 2:1.
      9. The wide spectrum spurious emissions plots shown on the following pages are used only for the purpose
             of emission identification. There were no emissions detected in the 30MHz – 1GHz frequency range, as
             shown in the subsequent plots.
