RF Exposure evaluation According to 447498 D01 General RF Exposure Guidance v05 The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√ f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR, where  f(GHz) is the RF channel transmit frequency in GHz  Power and distance are rounded to the nearest mW and mm before calculation  The result is rounded to one decimal place for comparison Worse case is as below: [2441 MHz 1.29 dBm（ 1.34 6 mW）output power] (1.34 6 mW /5mm) ·[√2.441 (GHz)]= 0.42 <3.0 for 1-g SAR Then SAR evaluation is not required

Set Span = approximately 5 times the 20 dB bandwidth, centered on a hopping channel. Set the RBW = 100 kHz. Set the VBW ≥ 3 x RBW. Set Detector = peak. Set Sweep time = auto couple. Set Trace mode = max hold. Allow trace to fully stabilize. Use the peak marker function to determine the maximum Maximumconducetedlevel. Note that the channel found to contain the maximum conduceted level can be used to establish the reference level.  Band-edge Compliance of RF Conducted Emissions Use the following spectrum analyzer settings: Span = wide enough to capture the peak level of the emission operating on the channel closest to the band-edge, as well as any modulation products which fall outside of the authorized band of operation Set RBW  1% of the span=100kHzSet VBW  RBW Set Sweep = autoSetDetector function = peakSetTrace = max hold Allow the trace to stabilize. Set the marker on the emission at the bandedge, or on the highest modulation product outside of the band, if this level is greater than that at the bandedge. Enable the marker-delta function, then use the marker-to-peak function to move the marker to the peak of the in-band emission. The marker-delta value now displayed must comply with the limit specified in this Section. Now, using the same instrument settings, enable the hopping function of the EUT. Allow the trace to stabilize.

It must be performed with the highest gain of each type of antenna proposed for use with the EUT. Use the following spectrum analyzer settings: The EUT was placed on a turn table which is 0.8m above ground plane. Maximum procedure was performed on the highest emissions to ensure EUT compliance. Span = wide enough to fully capture the emission being measured RBW = 1 MHz for f  1 GHz(1GHz to 25GHz), 100 kHz for f < 1 GHz(30MHz to 1GHz) VBW  RBW Sweep = auto Report No. ES200415023W Page 49 of 63 Ver.1.0 Detector function = peak Trace = max hold Follow the guidelines in ANSI C63.10-2013 respect to maximizing the emission by rotating the EUT, measuring the emission while the EUT is situated in three orthogonal planes (if appropriate), adjusting the measurement antenna height and polarization, etc. A pre-amp and a high pass filter are required for this test, in order to provide the measuring system with sufficient sensitivity. Allow the trace to stabilize. The peak reading of the emission, after being corrected by the antenna factor, cable loss, pre-amp gain, etc., is the peak field strength, which must comply with the limit specified in Section 15.35(b). Submit this data. Now set the VBW to 10 Hz, while maintaining all of the other instrument settings. This peak level, once corrected, must comply with the limit specified in Section 15.209. If the dwell time per channel of the hopping signal is less than 100 ms, then the reading obtained with the 10 Hz VBW may be further adjusted by a “duty cycle correction factor”, derived from 20log(dwell time/100 ms), in an effort to demonstrate compliance with the 15.209 limit. Submit this data. Repeat above procedures until all frequency measured was complete. 9.7.5 Test Results  Spurious Emission below 30MHz(9KHz to 30MHz) Temperature: 27°C Test Date: May 14, 2020 Humidity: 43 % Test By: XW Test mode: TX Mode Freq.
