Report No.: HCT-RF-1806-FC010                                                             FCC ID: ZNFX210JM


   3. TEST METHODOLOGY
   The measurement procedure described in the American National Standard of Procedures for
   Compliance Testing of Unlicensed Wireless Devices (ANSI C63.10-2013) is used in the
   measurement of the test device.


   3.1 EUT CONFIGURATION
   The EUT configuration for testing is installed on RF field strength measurement to meet the
   Commissions requirement and operating in a manner that intends to maximize its emission
   characteristics in a continuous normal application.


   3.2 EUT EXERCISE
   The EUT was operated in the engineering mode to fix the Tx frequency that was for the purpose of
   the measurements. According to its specifications, the EUT must comply with the requirements of
   the Section 15.207, 15.209 and 15.247 under the FCC Rules Part 15 Subpart C.


   3.3 GENERAL TEST PROCEDURES
   Conducted Emissions
   The EUT is placed on the turntable, which is 0.8 m above ground plane. According to the
   requirements in Section 6.2 of ANSI C63.10. (Version :2013) Conducted emissions from the EUT
   measured in the frequency range between 0.15 MHz and 30MHz using CISPR Quasi-peak and
   average detector modes.
   Radiated Emissions
   The EUT is placed on a turn table, which is 0.8 m above ground plane below 1GHz. Above 1GHz
   with 1.5m using absorbers between the EUT and receive antenna. The turntable shall rotate 360
   degrees to determine the position of maximum emission level. EUT is set 3.75 m away from the
   receiving antenna, which varied from 1 m to 4 m to find out the highest emission. And also, each
   emission was to be maximized by changing the polarization of receiving antenna both horizontal
   and vertical. In order to find out the max. emission, the relative positions of this hand-held
   transmitter (EUT) was rotated through three orthogonal axes according to the requirements in
   Section 8 of ANSI C63.10. (Version: 2013). To record the final measurements, the analyzer
   detector function was set to CISPR quasi-peak mode and the bandwidth of the spectrum analyzer
   was set to 120 kHz for frequencies below 1 GHz or 1 MHz for frequencies above 1 GHz. For
   average measurements above 1 GHz, the analyzer was set to peak detector with a reduced VBW
   setting(RBW = 1 MHz, VBW = 1/T Hz, where T = Pulse width).
   Conducted Antenna Terminal
   See Section from 7.8.2 to 7.8.8.(ANSI 63.10-2013)

   9. TEST RESULT
   9.1 PEAK POWER
   LIMIT
   The maximum peak output power of the intentional radiator shall not exceed the following:
   1. For frequency hopping systems operating in the 2400–2483.5 MHz band employing at least 75
     non-overlapping hopping channels, and all frequency hopping systems in the 5725–5850 MHz
     band: 1 W. For all other frequency hopping systems in the 2400-2483.5 MHz band: 0.125 W.
   2. The conducted output power limit specified in paragraph (b) of this section is based on the use
     of antennas with directional gains that do not exceed 6 dBi.


   Test Configuration

        Bluetooth Tester
                                          Spectrum Analyzer




      EUT             Power Splitter




   TEST PROCEDURE
   The transmitter output is connected to the Spectrum Analyzer. The Spectrum Analyzer is set to the
   peak detector mode. This test is performed with hopping off.


   The Spectrum Analyzer is set to (7.8.5 in ANSI 63.10-2013)
     1) Span: approximately 5 times the 20 dB bandwidth, centered on a hopping channel
     2) RBW > the 20 dB bandwidth of the emission being measured
     3) VBW ≥ RBW
     4) Sweep = Auto
     5) Detector = Peak
     6) Trace = Max hold


   SAMPLE CALCULATION
   Output Power = Spectrum Reading Power + Power Splitter loss + Cable loss(2 ea)
                   = 10 dBm + 6 dB + 1.5 dB = 17.5 dBm
   Note :
   1. Spectrum reading values are not plot data. The power results in plot is already including the actual values
     of loss for the splitter and cable combination.
   2. Spectrum offset = Power Splitter loss + Cable loss

   3. We apply to the offset in the 2.4 GHz range that was rounded off to the closest tenth dB. Actual value of
     loss for the splitter and cable combination is 7.36 dB at 2402 MHz and is 7.44 dB at 2480 MHz.
     So, 7.4 dB is offset. And the offset gap in the 2.4 GHz range do not affect the conducted peak power final
     result.

   9.2 BAND EDGES
   LIMIT
   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, provided the transmitter demonstrates compliance with
   the peak conducted power limits.

   9.3 FREQUENCY SEPARATION / OCCUPIED BANDWIDTH (99% BW)
   LIMIT
   According to §15.247(a)(1), 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.


   Test Configuration

        Bluetooth Tester
                                        Spectrum Analyzer
        Test Set (E5515C)




      EUT             Power Splitter




   TEST PROCEDURE
   The Channel Separation test is performed with hopping on. And the 20 dB Bandwidth test is
   performed with hopping off.
   The Spectrum Analyzer is set to (7.8.2 in ANSI 63.10-2013)
     1) Span: Wide enough to capture the peaks of two adjacent channels
     2) RBW: Start with the RBW set to approximately 30% of the channel spacing; adjust as
           necessary to best identify the center of each individual channel.
     3) VBW ≥ RBW
     4) Sweep: Auto
     5) Detector: Peak
     6) Trace: Max hold
     7) All the trace to stabilize.
   Use the marker-delta function to determine the separation between the peaks of the adjacent
   channels. Compliance of an EUT with the appropriate regulatory limit shall be determined. A plot of
   the data shall be included in the test report.


   TEST RESULTS
   No non-compliance noted

       Note : We can not know what use channel in AFH mode. So, we can not test in AFH mode. Also, if the test
       performs some channel in AFH mode, the test result is not different with normal mode.
