The EUT is placed on a turntable, which is 1.5m above the ground plane and worked at highest radiated power. 2. The turntable was rotated for 360 degrees to determine the position of maximum emission level. 3. EUT is set 3m away from the receiving antenna, which is varied from 1m to 4m to find out the highest emission. 4. Set the spectrum analyzer in the following setting in order to capture the lower and upper band-edges of the emission: (a) PEAK: RBW=1MHz; VBW=3MHz; Sweep=AUTO (b) AVERAGE: RBW=1MHz; VBW=10Hz; Sweep=AUTO 6.4.Test Results Pass (The testing data was attached in the next pages.)

RF Cable Hubersuhner SUCOFLEX106 505238/6 Apr.23,18 1 Year 7.2.Limit For direct sequence systems, the minimum 6dB bandwidth shall be at least 500kHz 7.3.Test Procedure Use the test method descried in ANSI C63.10 Section 11.8.2: The automatic bandwidth measurement capability of an instrument may be employed using the X dB bandwidth mode with X set to 6 dB, if the functionality described in 11.8.1 (i.e., RBW = 100 kHz, VBW ≥ 3 × RBW, and peak detector with maximum hold) is implemented by the instrumentation function. When using this capability, care shall be taken so that the bandwidth measurement is not influenced by any intermediate power nulls in the fundamental emission that might be ≥6 dB. Use the test method descried in ANSI C63.10 Section 6.9.2: The occupied bandwidth is the frequency bandwidth such that, below its lower and above its upper frequency limits, the mean powers are each equal to 0.5% of the total mean power of the given emission. The following procedure shall be used for measuring 99% power bandwidth: a) The instrument center frequency is set to the nominal EUT channel center frequency. The frequency span for the spectrum analyzer shall be between 1.5 times and 5.0 times the OBW. b) The nominal IF filter bandwidth (3 dB RBW) shall be in the range of 1% to 5% of the OBW, and VBW shall be approximately three times the RBW, unless otherwise specified by the applicable requirement. c) Set the reference level of the instrument as required, keeping the signal from exceeding the maximum input mixer level for linear operation. In general, the peak of the spectral envelope shall be more than [10 log (OBW/RBW)] below the reference level. Specific guidance is given in 4.1.5.2. d) Step a) through step c) might require iteration to adjust within the specified range. e) Video averaging is not permitted. Where practical, a sample detection and single sweep mode shall be used. Otherwise, peak detection and max hold mode (until the trace stabilizes) shall be used. f) Use the 99% power bandwidth function of the instrument (if available) and report the measured bandwidth. g) If the instrument does not have a 99% power bandwidth function, then the trace data points are recovered and directly summed in linear power terms. The recovered amplitude data points, beginning at the lowest frequency, are placed in a running sum until 0.5% of the total is reached; that frequency is recorded as the lower frequency. The process is repeated until 99.5% of the total is reached; that frequency is recorded as the upper frequency. The 99% power bandwidth is the difference between these two frequencies.

FCC ID:AK8SRSXB402 h) The occupied bandwidth shall be reported by providing plot(s) of the measuring instrument display; the plot axes and the scale units per division shall be clearly labeled.

Maximum Conducted Output Power is defined as the total transmit power delivered to all antennas and antenna elements averaged across all symbols in the signaling alphabet when the transmitter is operating at its maximum power control level. 8.3.Test Procedure 1, Connected the EUT’s antenna port to Spectrum Analyzer. 2, Use the test method descried in ANSI C63.10 clause 11.9.2.2.2: 1) Set span to at least 1.5 times the OBW. 2) Set RBW = 1% to 5% of the OBW, not to exceed 1 MHz. 3) Set VBW ≥ [3 × RBW]. 4) Number of points in sweep ≥ [2 × span / RBW]. (This gives bin-to-bin spacing ≤ RBW / 2, so that narrowband signals are not lost between frequency bins.). 5) Sweep time = auto. 6) Detector = RMS (i.e., power averaging), if available. Otherwise, use sample detector mode. 7) If transmit duty cycle < 98%, use a sweep trigger with the level set to enable triggering only on full power pulses. The transmitter shall operate at the maximum power control level for the entire duration of every sweep. If the EUT transmits continuously (i.e., with no OFF intervals) or at duty cycle ≥ 98%, and if each transmission is entirely at the maximum power control level, then the trigger shall be set to “free run.”. 8) Trace average at least 100 traces in power averaging (rms) mode. 9) Compute power by integrating the spectrum across the OBW of the signal using the instrument’s band power measurement function, with band limits set equal to the OBW band edges. If the instrument does not have a band power function, sum the spectrum levels (in power units) at intervals equal to the RBW extending across the entire OBW of the spectrum. Note: The cable loss and attenuator loss were offset into measure device as an amplitude offset. Audix Technology (Shenzhen) Co., Ltd. Report No. ACS-F19022 Page 61 of 70
